FC-TSRO-0824 | Honeywell | Digital Output Field Termination Assembly

Description:

Field termination assembly module TSRO-0824 is the interface between system interconnection cable SICC-0001/Lx and the external field wiring (screw terminals). It has eight relay-based potential-free safe output channels suitable for applications up to and including SIL3 without the use of fault exclusions. TSRO-0824 complies with safety requirements for general use in safety requirement classes SIL3 as defined in IEC 61508.

The TSRO-0824 has floating, non-commoned, output contacts that can be wired independently. Each output channel consists of:

• Three relays
• A fused NO field contact (5 AT, slow-acting)
• A status indication LED
