Honeywell MU-TDOR22 51304427-100 | Digital Output Relay Module 16-Channel

Product Description

The MU-TDOR22 (51304427-100) is a high-density digital output assembly designed for the Honeywell Process Manager (PM), Advanced Process Manager (APM), and High-Performance Process Manager (HPM) families. This module provides 16 isolated channels, each capable of being independently configured via physical jumpers to operate as either Form A (Normally Open) or Form B (Normally Closed) contacts.

Utilizing premium silver alloy contact material, the MU-TDOR22 (51304427-100) ensures long-term switching reliability in demanding industrial control loops. The hardware architecture is specifically engineered for high-voltage isolation, protecting the system backbone from field-side transients.

Application Scenarios

The MU-TDOR22 (51304427-100) is typically deployed for heavy-duty switching tasks where standard electronic outputs lack sufficient current capacity or isolation. Common use cases include:

• Interfacing with motor starters and solenoid valves.

• Integrating non-standard field voltage signals into the DCS.

• Emergency shutdown (ESD) auxiliary signaling.

• Pilot light and alarm annunciator control.

Frequently Asked Questions

How is the contact logic changed from NO to NC?

The logic for each channel on the MU-TDOR22 (51304427-100) is determined by the physical position of the onboard jumpers. This must be configured prior to installation to match the field device requirements.

Does this module support inductive loads?

Yes, it is rated for 1/8 HP; however, for highly inductive DC loads, external surge suppression (such as a flyback diode) is recommended to maximize the lifespan of the silver alloy contacts.
