Technical Description & Instructions
The module functions as a “sink” input, meaning the field device must provide the voltage. It includes status LEDs on the front panel for each channel, allowing for rapid onsite troubleshooting.
- Mounting: The module is “hot-swappable” and plugs into a ModuleBus terminal base (e.g., TU810 or TU812).
- Configuration: Filter times and channel settings are defined via the ABB Engineering Suite (Control Builder).
- Safety: The module incorporates current-limiting circuitry to protect internal components from field surges.
