Honeywell CC-TDOB01 51308371-175 Digital Output Module
Configured for discrete control execution in Honeywell Experion Series C I/O backplane platforms, the Honeywell CC-TDOB01 (51308371-175 Digital Output Module) provides direct physical/electrical execution. The module manages discrete state switching across 32 independent output channels to actuate solenoid valves, pumps, motor starters, and field indicators. Integrated relay contacts translate high-level system logic commands into physical circuit switching while maintaining a 1500 V isolation barrier to prevent field noise, inductive spikes, and electrical transients from entering host backplane logic circuits.

Channel-to-Channel Isolation & Backplane Protection
The CC-TDOB01 features robust channel-to-logic isolation rated at 1500 V to isolate internal microprocessors from field load disturbances. Dry contact SPDT relays maintain galvanic separation between external power sources and host Experion backplane communication lines. This isolation suppresses common-mode voltage offsets, ground potential loops, and high-voltage transients generated by switching inductive field loads. Integrated channel-level protection ensures continuous execution across dense I/O configurations without signal cross-talk or logic reset events.
Frequently Asked Questions
Q: What contact configuration is provided on each of the 32 discrete output channels?
A: Each channel provides an independent Form C single-pole double-throw (SPDT) dry contact relay capable of switching external 24 VDC loads up to 0.5 A.
Q: How is logic power supplied to the CC-TDOB01 module?
A: Operating power for internal logic and relay coil activation is drawn directly from the 24 VDC Experion Series C backplane carrier upon insertion.
Q: What grounding precautions must be observed during field wiring termination?
A: Cable shields must be terminated at a single earth ground point on the cabinet enclosure bus bar to prevent high-frequency noise coupling onto discrete switching control lines.
Field Installation Guidelines
- Mount the CC-TDOB01 I/O carrier directly onto standard DIN rail, ensuring the locking mechanisms click firmly into place.
- Align the module rear edge connector pins with the carrier receptacle and press evenly until the locking latches engage.
- Wire field device loads to the Form C terminal blocks, verifying that continuous current draw does not exceed 0.5 A per point at 24 VDC.
- Route field output cables away from high-power AC distribution lines by a minimum of 20 cm to mitigate inductive coupling.
- Apply 24 VDC backplane power and perform functional channel toggling via system software to verify output relay coil switching states.
