Honeywell TC-ODJ161 | 16-Channel Isolated Digital Output Module 24VDC

Product Description

The TC-ODJ161 is a high-capacity discrete output module designed for the Honeywell Experion PKS and PlantScape controller platforms. This module provides 16 isolated output points, allowing for the independent switching of 24VDC field loads. Engineered for high-demand industrial environments, it features robust electrical isolation to protect the internal controller backplane from field-side voltage spikes and electrical noise, ensuring consistent uptime in mission-critical applications.

Implementation and Load Management

The TC-ODJ161 is frequently utilized for driving high-current field devices such as solenoid valves, motor starters, and large relays. While individual channels can handle peak currents up to 2.0 Amps, system designers must ensure that the simultaneous activation of multiple outputs does not exceed the aggregate 8.0 Amp module limit. Proper heat dissipation within the enclosure is recommended when operating at high current densities.

Frequently Asked Questions

• What is the benefit of the isolated channel design?

  Isolation ensures that a fault or short circuit on one field device does not propagate to other channels or damage the sensitive electronics of the PLC backplane.

• Can this module drive AC loads?

  No, the TC-ODJ161 is specifically designed for DC current switching. For AC applications, a dedicated relay or Triac output module should be used.
