FC-TSRO-08UNI Honeywell Field Termination Aassembly (FTA) Module

Overview

The TSRO-08UNI is a field termination assembly (FTA) module designed for safe common external power relay output in SIL3 applications. It acts as an interface between the system interconnection cable (SICC-0001/Lx) and the external field wiring via screw terminals, featuring eight relay-based safe output channels. This module meets the safety requirements for applications up to SIL3 as defined in IEC 61508, without the need for fault exclusions.

Features

• Eight Relay-Based Safe Output Channels: Each channel includes three relays and a fused normally open (NO) field contact (2 A, slow-acting).
• Status Indication LED: Indicates the energized relay state.
• High Load Switching Capability: Capable of switching loads up to 115/230 V AC, providing reliable outputs for Safety Manager in SIL3 applications.
• Safety Compliance: Suitable for use in safety requirement classes up to SIL3.
