ABB Advant® Master S100 I/O system

ABB Advant® Master S100 I/O system

The S100 I/O process interface modules for Advant Controller 400 series process controllers come with connection units, simplifying cable termination and keeping noise and destructive spikes away from the central electronics.

with the host controller, it is the right choice for centralized I/O systems and high-speed applications.

The range of process I/O modules is complete, consisting of general purpose digital and analog inputs and outputs and special interfaces for special tasks. 

These specials include pulse counting, frequency measuring, positioning, motor speed control and communication with other controllers. 

All I/O modules provide simple interfacing, accurate - yet fast - control, and easy integration of individual loops into a comprehensive plant-wide control and supervision system.

The interface modules connect to the process through screw terminals on connection units normally installed inside, at the back of the cabinet.

This solution keeps noise and destructive voltage spikes away from the central electronics and provides a neat and tidy process interface that is easy to maintain.

Prefabricated cables interconnect modules with connection units. 

The cables come in different lengths, permitting termination and marshalling in controller cabinets, in adjacent cabinets, or in cabinets a greater distance away.

There are connection units that support signaloriented or device-oriented field wiring. 

The former means that field wires with the same electrical characteristics (e.g. all 24 V d.c. inputs) are grouped and terminated together, the latter that field wires to/from the same field devices are grouped and terminated together. 

The combination means maximum installation flexibility.

On-board processing capabilities

The process I/O modules are “intelligent” in the sense that module-related signal and data processing is performed on board as opposed to centrally, by the CPU of the host controller. 

Time tagging of events, filtering and gain control are some examples of board-level tasks. 

This functional distribution improves real-time performance and reliability of the system as a whole and maintains processing capacity when the system is expanded.

High disturbance immunity

All modules conform to the highest standards of electromagnetic noise immunity and satisfy the requirements of the EU directives 2014/30/EU and 2014/35/EU. 

For the above reasons, S100 I/O is likely to be the best help you can get for putting your control system in touch with your field devices.

Specification

Analogue Input Module

DSAI 130A: 16-channel, differential input method, supports ±10 V/±20 mA input signal. The resolution is 12 bits + sign, common mode voltage (CMV) ≤ 50 V, 

common mode rejection ratio (CMRR) at 50 Hz is more than 100 dB, which can effectively suppress the common mode interference and ensure high-precision analogue signal input.

DSAI 133A1: 32-channel, single-ended input, can receive signals of 0...+10 V/0...+20 mA, with 12-bit resolution, suitable for scenarios requiring a high number of channels and relatively moderate signal accuracy.

DSAI 146: 31 measurement channels and 1 reference channel for temperature measurements from - 100...+320/-200...+640°C with Pt100 sensor and 3-wire connection with 12 bit resolution + symbols for specific requirements in temperature measurement.

DSAI 155A: 14 measurement channels, 2 reference channels and 1 compensation channel for thermocouple signals B, C, E, J, K, R, S and T. 

The output signal can be grounded or floated and has a resolution of 12/13 bits + symbols, a CMV of ≤ 16 V, and a CMRR of > 100 dB at 50 Hz for thermocouple signal measurement and processing.

Digital Input Modules

Multiple voltage specifications: 

Supports a wide range of input voltages such as 24 V d.c., 24/48 V d.c., 48 V d.c., 110 V d.c., or 120 V a.c., 230 V a.c., etc.

General characteristics: all 32 channels, divided into 4 groups, using optical isolation technology, can be read by scanning or interrupting the signal,

can effectively isolate the external electrical interference, to ensure the accurate input of digital signals.
