Process Control & Channel Isolation
The Honeywell FTA-T-20 provides physical interface termination between control system output cards and field devices. Designed for process control installations, the assembly incorporates channel-to-channel isolation to prevent electrical interference and ground loops across signal paths. Operating at 220 VAC with signal processing capabilities up to 30 kHz, the board maintains clean output transmission across discrete control loops.Frequently Asked Questions
Q: What is the main physical purpose of the FTA-T-20 assembly?A: The board functions as a Field Termination Assembly (FTA) to interface logic controller output channels directly with field wiring field devices.Q: How does channel-to-channel isolation benefit the field wiring connections?A: Channel-to-channel isolation prevents electrical cross-talk, common-mode noise, and transient voltage spikes from propagating between individual output loops or back into the main system rack.Field Installation Guidelines
- Mount the module onto the dedicated DIN rail or cabinet termination rack using the integral retaining latches.
- Verify that field supply power is de-energized before connecting high-voltage wiring to the terminal blocks.
- Strip field wires to the specified length and torque terminal screws according to standard cabinet wiring practices.
- Ensure signal cable shielding is grounded at a single common earth ground point to minimize electro-magnetic interference.
- Check line continuity and load impedance before applying the 220 VAC system operating power.
