The ABB GJR5251600R0101 (Type: ICDT 08 B5) is a versatile 8-channel Analog Input Module belonging to the Procontic CS31 remote I/O family. This module acts as a remote station on the CS31 system bus, allowing for high-resolution data acquisition across long distances. It is designed for maximum flexibility, offering 12-bit resolution and channels that are configurable in pairs to support voltage, current, and temperature sensors (RTDs and Thermocouples), making it a comprehensive solution for complex process monitoring.
The ICDT 08 B5 features an advanced internal control circuit that performs cyclic self-calibration to ensure long-term measurement stability. Configuration of the input types and the CS31 bus address is performed locally via DIL switches. The module utilizes one address in the word input range, with each of the eight channels occupying 16 bits. To ensure system integrity, the CS31 system bus connection is electrically isolated from the internal module electronics and power supply.
| Parameter | Specification Details |
|---|---|
| Order Code | GJR5251600R0101 / GJR5251666R1001 |
| Type Designation | ICDT 08 B5 (ICDT08B5) |
| Number of Inputs | 8 Channels (Configurable in pairs) |
| Resolution | 12 Bits |
| Voltage Ranges | ± 10V, ± 5V, ± 500mV, ± 50mV |
| Current Ranges | 0...20 mA, 4...20 mA (via external 250 Ω shunt) |
| Temperature Sensors | Pt100, Pt1000, Thermocouples (Types J, K, S) |
| Power Supply | 24 V DC |
| Bus Connection | CS31 System Bus (Electrically Isolated) |
| Conversion Time | 1355 μs |
The module is equipped with an intuitive diagnostic interface on the front panel:
Channel LEDs: 8 green LEDs used for channel selection and detailed diagnosis, plus 8 green LEDs providing a rough visual representation of analog values.
Error Indicators: A dedicated Red LED for immediate error notification.
Test Function: A front-mounted Test Button used to cycle through diagnostic information.
Reference List: A printed list of diagnostic codes located on the front panel for quick troubleshooting of sensor or bus faults.
Sensor Compatibility: Only electrically isolated sensors may be used with the ICDT 08 B5. If using non-isolated sensors, external signal isolators must be installed to prevent ground loops that could damage the 12-bit conversion circuitry.
Current Measurement: To measure 0...20 mA or 4...20 mA signals, the module must be configured for the 5V range and an external 250 Ω precision shunt must be installed across the input terminals.
Mounting: The unit is designed for industrial flexibility; it can be snapped onto a 15-mm-high DIN rail or fastened directly to a mounting plate using four screws.
Configuration: Before commissioning, verify that the DIL switches match the intended sensor types for each pair of channels. Changing DIL switch settings typically requires a module power cycle to register the new configuration.
The ABB ICDT 08 B5 provides a high-density, multifunctional analog interface that reduces the need for multiple specialized modules. Its built-in linearization for Pt100/Pt1000 and standard thermocouples simplifies PLC programming by providing direct, scaled values to the CS31 master. For B2B procurement and maintenance, the GJR5251600R0101 is a critical component for maintaining the accuracy and reliability of legacy Procontic CS31 installations, offering a robust bridge between field instrumentation and the central control system.
