ABB GJR5251600R0202 07AIC91-AD:Analog Input module 16AI
Why Choose the ABB 07AI91 AC31 Analog Input Module [07AI91-AD]?
The ABB 07AI91 (order code 07AI91-AD, ABB part number GJR5251600R0202) is an analog input module for the Advant Controller 31 (AC31) range, connecting to the CS31 system bus. It is designed for accurate measurement of temperature, voltage and current signals in industrial automation.
The input channels can be configured in pairs for a wide range of sensors, including ±10 V / ±5 V / ±500 mV / ±50 mV voltage, 4–20 mA current (with an external 250 Ω resistor), Pt100 / Pt1000 RTDs with linearisation, and thermocouple types J, K and S with linearisation. The CS31 bus connection is electrically isolated for dependable signal integrity.
