Overview
The 3BHE029153R0101 UNS0119A-P,V101 is a digital input submodule for ABB Advant OCS and Advant-800xA systems. It acquires field signals, conditions their states, and transfers the results to the controller. This module operates with a 5 V DC back-plane supply and a 24 V DC field-loop supply, making it suitable for direct connection to dry contacts or DC proximity switches.
Signal Characteristics and Thresholds
The submodule accepts 24 V DC field-loop power and draws 4 mA at 24 V. It recognizes an ON state at 15 V or higher and an OFF state at 5 V or lower. A 2 V hysteresis band prevents chatter from signal noise. Furthermore, the 200 µs minimum pulse width captures short-duration events reliably without external pulse-stretching circuitry.
Electrical Isolation and Power Dissipation
The module provides 500 V AC isolation between channels and the back-plane, which protects the controller from field-side transients. Total power dissipation stays low, with a typical value of 2 W and a maximum of 3 W. The back-plane draws 5 V DC at 250 mA, while the field loop uses 24 V DC at 30 mA.
Environmental and Mechanical Data
For horizontal rail mounting, the submodule operates from -10 to +60 °C and stores from -20 to +70 °C. In addition, it tolerates 10 to 90 % relative humidity non-condensing. These specifications allow deployment in standard industrial enclosures without extra climate control.

Frequently Asked Questions
Q: What field signal types can the 3BHE029153R0101 UNS0119A-P,V101 accept?
A: It works with 24 V DC digital inputs, such as dry contact closures or DC proximity switch outputs. The 4 mA input current and 15 V turn-on threshold match standard industrial sensors.
Q: Can I install this submodule without powering down the rack?
A: The documentation does not confirm hot-swap support. Therefore, always follow the Advant OCS system manual for power-down and ESD precautions during installation or removal.
