ABB DI825 Module

Core Performance & Industrial Application

The ABB DI825 (3BSE036373R1) is an 8-channel 125 VDC current-sinking digital input module for the S800 I/O system of System 800xA / Freelance DCS.

Input "1" range 71-156 V; "0" range 0-20 V; 3.0 mA at 125 V; 41.5 kΩ input impedance; channels individually optically isolated.

SOE event recording with 0.4 ms resolution; selectable digital filter 0-100 ms; channel 1/8 can supervise process voltage for channel groups; front Fault/Run/Warning and channel LEDs.

It mounts on TU811/TU813/TU831/TU839/TU851 termination units as spare replacement.
