Honeywell TC-ODJ161 Experion Digital Output Module

The Honeywell TC-ODJ161, also cataloged as the TC-ODJ161 Digital Output Modules, operates as a dedicated hardware component for discrete high-current load switching within Experion PKS system architecture platforms.

Hardware Specifications

Channel Isolation & High-Density DC Switching Performance

The TC-ODJ161 utilizes individual galvanic barriers to isolate each of its 16 output channels up to 1500 VAC RMS relative to the chassis backplane. Designed for high-density 24 VDC discrete switching, the unit delivers up to 2.0 A per point at 30 deg C while maintaining off-to-on response times under 1.0 ms. The integrated solid-state output architecture prevents ground loop coupling and protects adjacent controller logic circuits from field-side inductive kickback voltage transients during heavy solenoid or relay coil de-energization.

Frequently Asked Questions

Q: Can individual channels on the TC-ODJ161 be hot-swapped without interrupting adjacent I/O modules?

A: The module supports removal and insertion under power on compatible active backplanes provided local cabinet hazardous area regulations and site safety procedures are followed.

Q: How does operating temperature affect the maximum current rating of the TC-ODJ161?

A: Per-point current rating derates linearly from 2.0 A at 30 deg C down to 1.0 A at 60 deg C, while total module capacity derates from 8.0 A down to 4.0 A.

Q: What terminal block assembly is required to connect field wiring to the TC-ODJ161?

A: Field connections attach via the dedicated TC-TBCH 36-position removable terminal block, allowing module exchange without disconnecting individual wire leads.

Field Installation Guidelines

1. Align the TC-ODJ161 module side guides with the chassis slot and push until the mechanical retention latch clicks firmly into position.
2. Mount the 36-position TC-TBCH terminal block onto the front module header assembly and verify secure latching.
3. Terminate 24 VDC field power and output load wiring to the TC-TBCH screw terminals, adhering to specified wire gauge and torque limits.
4. Route field conductors in separate wiring trunks away from sensitive communication lines and connect cable shields to the cabinet ground bar at a single point.
