ABB GJR5252300R3101 07AC91H Analog Input/Output Module

ABB GJR5252300R3101 07AC91H Analog Input/Output Module

Product core positioning

This module is a configurable analog input/output unit launched by ABB for the industrial automation field. The model number GJR5252300R3101 is the internal material code, and 07AC91H is the series identifier. It is a key component of the AC 31 series module. Its core function is to achieve bidirectional interaction between on-site analog signals (such as temperature and pressure) and control systems. It can convert sensor signals into digital signals for PLC/upper computer processing, and also output analog commands to drive actuators (such as valves and frequency converters).

Key technical parameters

Total number of channels: 16 configurable channels, supporting input/output function switching

Mode configuration:

12 bit mode: 8 inputs+8 outputs, each can be independently set to ± 10V, 0~10V voltage, or 0~20mA current signal

8-bit mode: 16 channel paired configuration, only supports 0~10V/0~20mA signal types

Accuracy and Response: Resolution 8/12 bit optional, measurement accuracy ± 0.1%, response time ≤ 1ms

2. System and electrical characteristics

Communication interface: Supports CS31 system bus (remote module role), some versions integrate RS485 interface compatible with Modbus protocol

Power supply and protection: 24VDC power supply, power consumption only 2W; protection level IP20, suitable for industrial environments

Environmental adaptability: Operating temperature range -40 ° C to 70 ° C, able to withstand harsh industrial temperature and humidity conditions

3. Physical and installation parameters

Size: approximately 100mm x 70mm x 35mm, weight 0.81kg

Installation method: DIN rail or screw fixation, compatible with standard industrial control cabinet layout

Core functions and features

Dual mode flexible switching: Select 8-bit/12 bit mode through DIL switch, balancing channel quantity and accuracy requirements. For example, the 12 bit mode is suitable for high-precision temperature control of chemical reaction vessels, while the 8-bit mode can meet the simple pressure monitoring of multiple points on the assembly line.
