FC-TSRO-08UNI | Honeywell | Relay Output Field Termination Assembly

The Honeywell FC-TSRO-08UNI is an 8-channel relay output field termination assembly designed for digital output signal processing in industrial automation systems. It interfaces controller output signals with higher-voltage or higher-current field devices while providing electrical isolation and output circuit protection.

Input Control and Switching Thresholds

The module operates at a nominal input control voltage of 24 Vdc, supporting a maximum input rating of 36 Vdc. The internal relays activate at a pick-up voltage threshold of 19.2 Vdc, ensuring positive contact switching and preventing unwanted actuation caused by control signal volt drops or floating inputs.

Output Contact Ratings and Protection

Equipped with 8 output channels, each output contact can switch loads up to 250 Vac or 250 Vdc. Each channel is individually fused to handle a maximum output current of 2 A, while supporting a minimum output switching threshold of 1 mA at 5 V for reliable low-power signaling.

Frequently Asked Questions

Q: What are the primary input activation limits for the FC-TSRO-08UNI?

A: The assembly operates at a nominal input voltage of 24 Vdc with a maximum voltage limit of 36 Vdc, and the relay pick-up voltage triggers reliably at 19.2 Vdc.

Q: What contact load capacity does each output channel support?

A: Each output channel handles up to 250 Vac or 250 Vdc with a fused maximum current of 2 A, and can switch low-level signals down to 1 mA at 5 V.
