07KT98 H4 GJR5253100R3262 ABB Analog I/O / Controller Module

Description

Product Role & System Fit

In ABB’s automation ecosystems—particularly in the Advant / AC31 / Advant OCS lines—the 07KT98 H4 GJR5253100R3262 functions as a hybrid analog I/O module. Rather than being purely an input or output board, it carries both measurement and output capabilities, enabling signal acquisition and actuator control from the same unit (within the limits of its channel architecture). According to listings, it is intended for use in I/O racks where the module communicates over ABB’s CS31 or equivalent bus, feeding data to a central controller.

When designing a system with multiple I/O zones, you can deploy 07KT98 modules in strategic positions where you need mixed signal handling—say, sensing temperature or pressure and also driving proportional valves. Their flexibility reduces the number of module types to stock and simplifies wiring. In many legacy installations, engineers place such modules close to the field devices (to minimize analog wiring distance) and rely on the bus to carry digitized data back to the CPU. Because the same module handles input and output, wiring and cable trays are optimized.

As a module within an ABB control architecture, 07KT98 H4 must align with the bus protocol, addressing, mapping in the I/O table, and compatibility with the surrounding modules (e.g. digital I/O, power supply, termination modules). Its place is not as a standalone controller, but as a peripheral module in a modular control system.

Product Model: 07KT98 H4 / GJR5253100R3262
Product Brand: ABB
Product Family / Series: Advant Controller / AC31 / Advant OCS I/O Modules
Key Features:

• Combined analog input and output module for ABB’s Advant / AC31 systems.
• Supports multiple input ranges (0–5 V, ±5 V, 0–10 V, ±10 V, 4–20 mA, etc.), and output channels with configurable ranges
• Designed for integration with CS31 bus architectures and rack-based I/O systems.
• Durable operating range (–20 °C to +70 °C) and IP20 protection rating per seller data

Technical Features & Benefits

Based on vendor descriptions, the 07KT98 H4 / GJR5253100R3262 brings several useful technical features:

• Analog Input & Output Support
  The module reportedly supports 8 analog input channels and 4 analog output channels, with input ranges like 0–5 V, ±5 V, 0–10 V, ±10 V, 4–20 mA, and even PT100 sensors (2- or 3-wire).  Outputs are configurable (e.g. 0–10 V, ±10 V, 0–20 mA).
• 12-bit Resolution
  The module uses 12-bit signed resolution for analog channels, giving decent granularity for control loops.
• Bus Compatibility & Interface
  It is built to interface with the CS31 system bus (or equivalent) common in ABB Advant systems.
• Operating Conditions
  The working temperature range is available in data: –20 °C to +70 °C is quoted from supplier data. It also has an IP20 protection rating under normal mounting conditions.
• Power & Current Specs (Inferred)
  Some sources list input current as 15 mA and output current up to 3 A. These values seem small for analog output, so they might relate to internal module bias or auxiliary supply rather than full load outputs.
• Diagnostics & Reliability
  Though less described publicly, modern ABB I/O modules typically include diagnostics for channel faults (open circuit, overrange), bus errors, and self-check routines. Use of galvanic isolation or buffered analog front ends helps shield against noise. The apt operating range also helps in harsh plant environments.
