FC-TSGASH-1624P V1.0 Field Termination Assembly | Honeywell

The Honeywell FC-TSGASH-1624P V1.0, also cataloged as the FC-TSGASH-1624P Field Termination Assembly, operates as a dedicated hardware component for 16-channel analog signal routing and power distribution within Honeywell Safety Manager platforms.

Hardware Specifications

4-20 mA HART Loop Protocol & Channel Isolation

The termination assembly conditions and channels 16 independent 0-20 mA analog signals while providing physical line interfaces for HART digital communication pass-through. Built-in channel-to-channel isolation circuits prevent potential ground loop shifts, cross-channel interference, and field line transients from propagating back to the safety processor. High-frequency filtering maintains analog loop integrity without attenuating bi-directional HART carrier signals overlaying the 4-20 mA current loops.

Frequently Asked Questions

Q: Does the FC-TSGASH-1624P V1.0 module require external power connections for field loops?

A: Yes, primary loop power is supplied through the onboard 24 VDC 2-pole connector to power connected 2-wire transmitters across all 16 channels.

Q: How is physical grounding established on the FC-TSGASH-1624P V1.0 terminal assembly?

A: Dedicated screw terminals are provided directly on the board assembly to connect field wire shield drains to the cabinet safety ground rail.

Q: Can HART communicators interface directly across the 0-20 mA channels?

A: Yes, all 16 analog input channels feature frequency-transparent impedance paths designed to support HART digital protocol communication.

Field Installation Guidelines

1. Snap the assembly firmly onto the DIN EN mounting rail until the retention clips engage securely.
2. Connect the main 24 VDC supply wiring to the 2-pole power connector with correct polarity.
3. Wire field loop conductors to the assigned screw terminal blocks according to the loop schematic.
4. Separate low-voltage analog cables from high-voltage AC conductors inside control panel wireways.
5. Secure all individual shield drain wires directly to the ground screw terminals to ensure full EMI noise rejection.
