07 AI 91 07AI91 GJR5251600R0202 ABB Advant OCS Analog I/O module

Description

Product Overview

The ABB 07-AI-91 analog input module provides versatile signal acquisition for industrial automation systems via the CS31 system bus. Featuring 8 configurable input channels (paired for flexibility), it supports diverse sensors, including ±10 V, ±5 V, ±500 mV, ±50 mV voltage inputs, 4…20 mA current loops (with a 250 Ω shunt), and linearized Pt100/Pt1000 or thermocouples (J/K/S). Designed for electrically isolated sensors, it ensures reliable performance with self-calibration, LED diagnostics, and DIL-switch configuration.
