EMAIL WHATSAPP
01 - FUNCTION
Logic-to-Load Relay Interface
The MC-TDOR12 51309148-175 is a conformally coated field termination assembly for 16 relay digital outputs. It provides compression-terminal field wiring for 120 VAC or 125 VDC switching in the Honeywell process I/O architecture.

It belongs to a coordinated output path: the compatible output processor, cable, FTA and field load must remain aligned.

TECHNICAL BUYER FAQ

MC-TDOR12 51309148-175 Questions

01 - Can MC-TDOR12 51309148-175 replace MC-TDOR52 51309148-275?

The relay class is related, but the field termination differs: TDOR12 uses compression terminals and TDOR52 uses screw terminals. Wiring hardware and cabinet practice determine whether conversion is acceptable.
02 - Is MC-TDOR12 51309148-175 the same as 51304443-150?

They share the MC-TDOR12 functional designation, but 51309148-175 is the CE part-number variant and 51304443-150 is the non-CE variant. Preserve the required approval status.
03 - Can MC-TDOR12 51309148-175 replace a solid-state output FTA?

No direct equivalence should be assumed. Relay and solid-state outputs differ in leakage, switching behavior, lifetime, fault mode and load compatibility.
04 - Why does contact duty matter for MC-TDOR12 51309148-175?

The 120 VAC / 125 VDC designation identifies the voltage class, not unlimited switching capability. Resistive, inductive and inrush loads impose different stress on relay contacts.
05 - Can MC-TDOR12 51309148-175 drive a 240 VAC field circuit?
MC-TDOR12 belongs to the 120 VAC / 125 VDC class. Honeywell identifies MC-TDOR22 and MC-TDOR62 as the 240 VAC / 125 VDC relay-output variants, so a 240 VAC application requires the correct architecture.
