Honeywell FTA-T-08 Fail-Safe Digital Output Relay FTA

Product Description

Configured for 24 V input control and four-channel relay switching, the Honeywell FTA-T-08 (FTA-T-08 Fail-Safe Digital Output Relay FTA) provides direct electrical execution for field devices. Each channel uses two relays from different manufacturers, a fused normally open field contact, and a status LED. The assembly supports 115/230 VAC relay output applications.

Hardware Specifications

Honeywell Process Control and Fail-Safe Relay Characteristics

The FTA-T-08 accepts a nominal 24 V input signal and actuates relay contacts for the corresponding field output. The specified relay cut-in voltage is 19 V, while the maximum input voltage is 31 V.

Each of the four channels uses two relays from different manufacturers. The channel also includes a fused normally open field contact rated with a 3.15 AT fuse and a status indicator LED. This arrangement provides a defined relay-contact path and local channel indication.

The associated FTA-E-08 provides the ELCO FTA interface, while the SIC-C-02 cable carries four signals in a 4/4 configuration. The terminal FTA designation is 1x4F.

The supplied data identifies 115/230 VAC relay output operation. Therefore, the external load circuit must match the applicable contact rating and installation requirements for the specific system configuration.

Frequently Asked Questions

Q: What input voltage does the FTA-T-08 use?
A: The nominal input voltage is 24 V. The specified maximum input voltage is 31 V, and the relay cut-in voltage is 19 V.

Q: How many output channels does the FTA-T-08 provide?
A: The module provides four independent digital output channels. Each channel uses two relays from different manufacturers.

Q: What cable connects the FTA-E-08 interface?
A: The supplied configuration specifies the SIC-C-02 cable, with four signals per SIC cable in a 4/4 arrangement.

Field Installation Guidelines

Mount the FTA assembly according to the mechanical requirements of the host Honeywell system. Secure the module and terminal connections before applying field power.

Verify the 24 V control supply against the specified input range before connecting the output circuits. Do not apply a voltage above the stated 31 V maximum input value.

Route control wiring separately from high-current or high-noise conductors where the cabinet design permits. Maintain secure terminal connections and prevent mechanical stress on the cable assembly.

Connect the SIC-C-02 cable according to the designated FTA-E-08 and terminal FTA configuration. Confirm channel identification before energizing the field circuits.

For the relay outputs, verify the external load voltage and current against the applicable relay-contact specification for the installed configuration. Check the 3.15 AT fused normally open field-contact path before commissioning.

Inspect the channel status LEDs during functional testing. Confirm that the commanded relay state corresponds to the intended field-device state before placing the circuit into service.
