Honeywell MC-GDOD12 51304642-175 Digital Output Field Terminal Assembly

The 51304642-175 (cataloged as the MC-GDOD12 Digital Output Field Terminal Assembly) is a dedicated hardware component manufactured by Honeywell for 24 VDC discrete output signal distribution and field-wiring termination. Designed for integration within Honeywell control architectures, this Size B terminal assembly provides 16 discrete output channels to link system controllers with field actuators securely.

Signal Distribution and Circuit Protection

The assembly features a conformally coated printed circuit board designed to withstand corrosive industrial atmospheres while maintaining channel-to-channel isolation across all 16 output loops. It interfaces with 24 VDC control loops to prevent ground potential migration between field devices and system backplane logic, utilizing robust trace routing to safeguard switching signals against inductive kickback.

Frequently Asked Questions

Q: Can the 51304642-175 terminal assembly be wired while cabinet power is active?

A: No. Power must be isolated and locked out from associated output cards and field actuators before connecting or disconnecting wires at the compression terminals.

Q: How many output channels does this terminal assembly support?

A: It supports 16 discrete output channels for 24 VDC signal distribution.
