Overview of Hesman MICE MS20/MS30 Series Switches

The Husman MICE (Modular Industrial Communication Equipment) series switches are high reliability network devices designed specifically for harsh industrial environments. MS20 and MS30, as the core products of this series, are ideal choices for building industrial automation networks due to their unique modular architecture, powerful redundancy functions, and extensive certification. This installation manual provides users with comprehensive guidance from unboxing inspection, safety precautions, mechanical and electrical installation to basic configuration.

These devices are designed to meet the special needs of industrial automation, comply with relevant industry standards, provide extremely high operational reliability even under extreme conditions, and ensure long-term stability and flexibility. This series of switches supports fanless design, can be installed on DIN rails, and provides multiple management methods, including web browsers, Telnet, V.24 interfaces, and network management software such as Industrial HiVision.

Core architecture and model analysis

2.1 Modular design concept

The core of MS20 and MS30 series switches is a basic module that includes all functional units such as switching, management, redundancy, display control, power connections, and media module slots. By inserting different media modules, users can flexibly select the required transmission medium (such as twisted pair or fiber optic) for each port, achieving true on-demand configuration. In addition, two additional media module slots can be added to specific models through the MB20 expansion module to further increase port density.

2.2 Comparison between MS20 and MS30 Series

The main difference between the two series lies in their support for gigabit ports:

MS20 series: Focused on providing a large number of 100Mbps ports. According to different models (MS20-0800, MS20-1600, MS20-2400), 2, 4, and 6 media module slots are provided respectively, which can support up to 8, 16, and 24 100Mbps ports.

MS30 series: In addition to providing 100Mbps ports, two additional Gigabit port slots have been added. Models such as MS30-0802, MS30-1602, and MS30-2402 provide the same number of 100Mbps ports as MS20, as well as 2 Gigabit ports to meet the demand for higher bandwidth.

2.3 Product Code and Model Identification

Husman's products identify device characteristics through a precise coding system. Each position in the product code represents a specific attribute, for example:

Position 1-4 (MS20/MS30): Identify the product series.

Position 6-9: Identify the number of 10/100 Mbit/s ports (e.g. 0800, 1600, 2400).

Position 10: Identify the operating temperature range (S: standard 0 ° C to+60 ° C; T/E: extended -40 ° C to+70 ° C).

Position 11: Identify the voltage range (A: 18-32V DC; C/E: 18-60V DC).

Position 12: Identify certification types (such as A, B, H, S, etc.), covering multiple standards such as CE, UL, ATEX, IEC 61850, etc.

Safety regulations and compliance

As a product aimed at industrial and potentially hazardous areas, the manual emphasizes safety operating procedures in a large amount of space and provides detailed information on various international certifications.

3.1 General Safety Warning

The manual uses three-level warning symbols of "Danger", "Warning", and "Caution" to remind users to pay attention to personal safety and the risk of equipment damage. Key warnings include:

Electric shock risk: It is strictly prohibited to insert sharp objects into the equipment or connection terminals, and do not touch the connection terminals during operation.

Fire risk: When connecting a power source that does not meet the requirements of Limited Power Source or NEC Class 2 and the output power exceeds 100W, the equipment must be installed in a cabinet or fire-resistant enclosure that meets the V-1 fire rating.

Overheating risk: During installation, it is necessary to ensure that all ventilation ducts are unobstructed and that there is at least 10cm of space in front of the equipment.

Equipment overheating: During installation, it is necessary to ensure that all ventilation ducts are unobstructed.

3.2 Hazardous Locations Use Certification

The MS20/MS30 series has passed strict hazardous area use certifications, including ATEX (EU), IECEx (International), and UKEX (UK) certifications, and is suitable for Class I, Division 2, Groups A, B, C, and D hazardous environments.

Authentication identification: The device is marked with an authentication code, such as II 3G Ex ec nC IIC T4 Gc.

Usage restrictions: When used in potentially explosive environments, the equipment must be installed in a casing that meets the IP54 protection level.

Power requirements: Measures must be taken to prevent transient interference at the voltage input port from exceeding 119V.

Connection restrictions: USB and V.24 interfaces are only used for temporary connections during maintenance, and connection or disconnection operations are strictly prohibited in hazardous environments.

Relay output: If a signal contact relay is used, the current must be limited to 100mA (resistive load).

3.3 Power Supply and Grounding

SELV/PELV power supply: The equipment is designed to use safe ultra-low voltage power supply and must be connected to SELV/PELV circuits that comply with IEC 60950-1 or IEC/EN 62368-1 standards.

Grounding: The lower panel of the equipment can be grounded through DIN rails or through independent grounding screws. The manual specifically warns that when supplying DC power, the negative terminal of the voltage input must be grounded.

Installation and Debugging Guide

The manual provides a detailed step-by-step installation guide to ensure that the equipment can be put into operation correctly and safely.

4.1 Mechanical Installation

DIN rail installation: The device can be easily installed on a 35mm DIN rail (compliant with DIN EN 60715 standard). When installing, hang the card slot on the upper part of the device into the guide rail, use a screwdriver to pull down the guide rail lock slider, press the lower part of the device against the guide rail, and then release the slider to lock it into place.

Media module installation: The media module supports hot swapping and can be installed or removed while the device is running. Insert the module into the slot from left to right and tighten the screws at the four corners during installation.

4.2 Electrical Connections

Power supply and signal contacts: Depending on different voltage ranges, the equipment is equipped with 4-pin or 6-pin pluggable terminal blocks for connecting the main power supply (supporting redundant power supply) and signal relay contacts. The signal contact is a passive relay contact that can be used for remote diagnosis. When there is a power failure, equipment failure, or link interruption, the contact opens and sends an alarm signal.

PoE power supply: For PoE media modules (such as MM22-T1T1T1), an external 48V DC power supply (recommended to use Husman RPS 60/48V EEC power supply) needs to be connected through a 3-pin terminal block to power the connected PD devices.

4.3 DIP switch configuration

The DIP switch at the bottom of the device is used to quickly configure critical redundant functions without entering the software interface.

4-pin DIP switch (standard type): configurable with RM (redundant manager) function, HIPER Ring ring port, and Stand by (backup coupling) function.

3-pin DIP switch (... E... model): Similar in function, but with slightly different definitions of ring network ports, and can achieve more complex combinations of redundant modes.

4.4 Data Cable Connection

Twisted pair port: It is recommended to use shielded cables in strong electromagnetic interference environments and ensure that power and data cables are routed separately, ideally at a 90 degree angle.

Fiber optic ports: When connecting, it is necessary to ensure that the port type matches (such as LH to LH, SX to SX), and pay attention to the attenuation and bandwidth length product of the optical cable.
