Honeywell Expert Series-C I/O Module

Honeywell Expert Series-C I/O Module

Basic Information

Document ID: EP03-490-520, Release 520, Version 1.5

Scope of application: Expert Series-C I/O modules and C300 controllers, supported since the Expert R300 version

Core component definition:

IOTA (Input Output Termination Assembly): A component that integrates I/O module fixation and on-site wiring functions. The module is directly plugged into IOTA without the need for an additional chassis

IOM (Input Output Module): A module equipped with core electronic components to achieve specific I/O functions and obtain power from IOTA

Core functions and design highlights

1. Universal design advantages

Compact integrated architecture: IOM and field terminals are integrated into IOTA, eliminating the need for independent electronic component chassis, significantly reducing device size, and improving cabinet space utilization

Convenient wiring and maintenance: using two-level "separable" terminals, convenient for on-site wiring installation and later maintenance; Supports up to 12AWG (2.5mm ²) multi strand wire access

Simplified power supply and redundancy: The on-site power supply is provided through IOTA, eliminating the need for additional power and manual wiring; Redundant configuration only requires adding a second IOM on IOTA, without the need for external cables or control devices

Efficient heat dissipation and layout:

Vertical installation design: Suitable for scenarios where on-site wiring is connected from the top/bottom of the cabinet

Tilted structure: optimizes air circulation inside the cabinet, improves heat dissipation efficiency, and adapts to high-density installation requirements

Information Ring "Identification: Quickly guide maintenance personnel to view equipment status information

Built in protection mechanism: Input/output circuits have short-circuit protection, no need to connect fuses in series, reducing installation and maintenance costs

2. IOTA multifunctional integration

IOTA serves as the core carrier, integrating multiple functions and reducing external component dependencies

Support switching between single module and redundant module configurations

Built in process signal termination and signal conditioning functions

Directly connect to networks such as FTE, I/O LINK, etc

Realize on-site power distribution without the need for external wiring grouping

Provide stable power supply for the inserted IOM

Module Classification and Key Specifications

The Series-C I/O module covers 8 major categories of signal processing requirements, with different modules focusing on parameters such as channel quantity, input/output range, and accuracy. The core classifications and representative module specifications are as follows:

1. Analog input module (AI)

Mainly used to receive current/voltage signals from transmitters or sensors, with some supporting the HART protocol for device configuration and status monitoring.

Module model, core function, channel number, input type/range, key characteristics

CC-PAIH01/02 with HART protocol 16 current (4-20mA), voltage (0-5V/1-5V/0.4-2V) 12 single ended+4 differential channels, supports open circuit detection, Class 1 Div 2 non flammable power supply

CC-PAIH51 with HART protocol 16 current only (4-20mA, 200 Ω load) full single ended channel, no voltage/differential input, supports HART device configuration

CC-PAIX01/02 does not have HART protocol. The current (4-20mA) and voltage (0-5V/1-5V/0.4-2V) are consistent with the parameters of CC-PAIH01/02 and do not have HART function

CC-PAIN01 without HART protocol 16 only current (4-20mA, 200 Ω load) full single ended channel, non flammable power supply, suitable for basic current signal acquisition

2. Temperature input module

Specially designed for thermocouples (TC) and thermistors (RTD), supporting low-temperature drift and high-precision temperature measurement.

Module model, core function, number of channels, support for sensor types, key characteristics

CC-PAIM01 (LLMUX) temperature multiplexing 64 (16 channels/FTU) TC (J/K/E/T/B/S/R, etc.), RTD (Pt100/Ni120/Cu10) need to be matched with PMIO FTA, support remote cold end compensation, 1-second scanning cycle

CC-PAIL51 low-level temperature input 16 TC/RTD (configurable per channel) directly integrated into Series-C IOTA, no external FTA required, operating temperature from -40 to+70 ℃

3. Pulse Input Module (PI)

Used for processing pulse generation equipment signals, suitable for measurement and trade handover scenarios, supporting high-precision frequency and cycle measurements.

Module model CC-PPIX01

Number of channels: 8 single channels/4 dual channels (can be mixed configuration)

Frequency range: Single channel 0-100kHz, dual channel 0-10kHz

Accuracy within the range of 0.5Hz-100kHz, ± 0.001% reading error

Key features support MeterSuite trade handover application, compliant with ISO 6551 standard, with "quick cut-off" function (1ms delay)

4. Analog Output Module (AO)

Output stable current signals to actuators and recorders, with partial support for HART protocol and configurable fault safety status.
