TC-ODK161 | 16-Channel 120/220 VAC Digital Output Module | Honeywell

Product Description

The TC-ODK161 is a high-density discrete AC output interface engineered for the Honeywell Experion PKS and legacy PLC rack systems. This module provides 16 independent points for switching alternating current loads, such as motor starters, solenoids, and industrial indicators. Designed to operate across a broad voltage range of 120 to 220 VAC, it offers robust switching capabilities for process-critical field devices while maintaining electrical isolation between the high-voltage field side and the sensitive controller backplane.

Load Management and Implementation

The TC-ODK161 is frequently utilized in legacy power distribution cabinets where high-voltage AC switching is required directly from the PLC. Its 2 Amp rating per point allows for the direct driving of many small-to-medium inductive loads without the need for interposing relays, thereby saving cabinet space and reducing wiring complexity. For optimal performance, users should ensure that the aggregate current across all 16 points does not exceed the thermal dissipation limits of the rack enclosure, especially when operating at the upper 220 VAC limit.

Frequently Asked Questions

• Can this module switch DC loads?

  No, the TC-ODK161 is specifically designed with Triac or similar AC switching components that require a zero-crossing or alternating current to function. For DC loads, a module like the TC-ODJ161 should be used.

• Is there fuse protection for individual channels?

  Most Honeywell digital output modules of this series incorporate internal protection; however, it is highly recommended to use external terminal block fusing to simplify maintenance and protect the module circuitry from field-side short circuits.
