Honeywell TK-ODJ161 Discrete DC Output Module
The Honeywell TK-ODJ161, also cataloged as the TK-ODJ161 DC Discrete Output Module, serves as the primary TK-ODJ161 Product Type utilized to execute discrete 24 VDC output distribution across Experion PKS, TPS, and TDC 3000 platforms. The hardware switches digital control commands into 16 discrete channels to actuate external relays, solenoids, alarms, and field instruments directly.
Suffix Breakdown & Model Matrix
The internal electronic layout remains identical across the family architecture, but physical installation footprints require selection between two distinct housing form factors:
- Variant 1: Standard compact mechanical block measuring 38 x 57 x 78 mm, optimized for specialized spacing.
- Variant 2: Elongated card assembly measuring 263 x 58 x 28 mm, designed to latch into standard chassis slots.

Process Control & Channel-to-Channel Isolation
The module incorporates channel-to-channel isolation networks that physically decouple field wiring faults from the inner processing logic, preventing electrical noise propagation into the system backplane. The discrete output paths handle inductive load spikes using embedded clamping diodes. This specific matrix configuration ensures that active 24 VDC loops do not induce cross-talk or voltage ripples into adjacent 4-20 mA HART loop protocol architectures or sensitive analog networks within the shared marshaling environment.
Frequently Asked Questions
Q: What is the maximum continuous current rating permitted on an individual output channel?
A: Each of the 16 discrete channels handles up to 1 A of continuous current, assuming overall thermal parameters do not exceed structural limits.
Q: Does the unit support live extraction or hot-swapping during standard operation?
A: The upstream active controller sub-rack power must be isolated prior to removing or inserting this module to prevent inductive voltage transients across the pins.
Q: How does the unit protect internal logic circuits against short circuits in field solenoids?
A: The internal printed circuit board features galvanic isolation barriers that prevent high-voltage surges and field-side grounding issues from affecting the core logic processing layer.
Field Installation Guidelines
- Isolate the main 24 VDC power supply bus before installing or removing the module enclosure.
- Secure the hardware inside a sealed, dust-resistant industrial enclosure to maintain protection against moisture and airborne particles.
- Ground all field cable shields at a single low-impedance master ground rail inside the marshaling cabinet.
- Route the discrete 24 VDC output cables away from low-level communication links to block high-frequency switching interference.
