Selection Suggestions
-
Choose for ABB System 800xA applications requiring 16 inputs and 16 outputs in one slot for 24–48VDC field devices.
-
If higher voltage (125VDC/240VAC) is required, use the UFC760BE142 variant.
-
For SIL 2 applications, use with external voting logic and periodic proof-testing (every 24 months).
-
Pair with matching ABB TU810 or TU830 termination unit.
Precautions
-
Output Grouping – All outputs share a common return. Ensure all outputs are powered from the same voltage source.
-
Output Current Limit – Total output current limited to 16A. Do not exceed this limit.
-
Wetting Current – For dry contacts, enable wetting current (5–15mA) for reliable switching.
-
Surge Current – Repetitive surge cycling may reduce module life; use external relays for frequent high-inrush loads.
-
Power Supply – The module draws 400mA from 24V aux plus output load. Ensure adequate capacity.
-
Firmware – Requires ABB firmware version compatible with System 800xA 6.0 or higher.
-
ESD Handling – Use ESD-safe practices when handling the module.
