Honeywell CC-TDOR01 51308376-175 Digital Output Relay Module

Overview

Configured for discrete relay output switching in Honeywell process control I/O systems, the Honeywell CC-TDOR01 51308376-175 (CC-TDOR01 Digital Output Relay Module) provides direct electrical switching between a 24 VDC control circuit and external relay loads. The module is rated for 0.5 A operation and provides electrical isolation up to 1500 VAC RMS or +/-1500 VDC.

Hardware Specifications

Process I/O Relay Isolation and Switching

The CC-TDOR01 switches discrete electrical loads through a relay output interface. Its specified 250 VAC RMS maximum load voltage and 125 VDC maximum load voltage define the upper load-voltage limits.

The module accepts loads down to 12 VDC and 100 mA minimum load current. Therefore, connected field devices should remain within the stated relay operating range.

The relay permits up to 10 A inrush current for 4 s at a 10% duty cycle. This specification applies to transient load conditions and should not be treated as the continuous 0.5 A operating rating.

The 1500 VAC RMS or +/-1500 VDC isolation specification separates the module’s control-side and load-side electrical domains. Consequently, installation should maintain appropriate wiring separation between control circuits and externally powered relay loads.

The 20 ms maximum turn-on and turn-off times define the relay switching response. Applications that require faster discrete switching should account for this hardware response before assigning timing limits in the control logic.

Frequently Asked Questions (FAQ)

Q: What is the maximum continuous output rating specified for the CC-TDOR01?

A: The supplied data identifies the module as a 0.5 A, 24 VDC digital output relay module. The maximum load voltage is 250 VAC RMS or 125 VDC.

Q: Can the relay handle an inrush current above 0.5 A?

A: Yes. The supplied specification permits a maximum inrush current of 10 A for 4 s at a 10% duty cycle. This does not replace the stated 0.5 A operating rating.

Q: What switching response does the module provide?

A: The specified maximum turn-on time is 20 ms, while the specified maximum turn-off time is also 20 ms.

Field Installation Guidelines

• Verify the module model and order number before installation: CC-TDOR01 51308376-175.
• Confirm that the connected load voltage remains within 250 VAC RMS or 125 VDC.
• Confirm that the field load meets the specified minimum load voltage of 12 VDC and minimum load current of 100 mA where applicable.
• Keep relay load wiring physically separated from low-level analog and communication wiring to reduce unwanted electrical coupling.
• Maintain appropriate insulation and clearance practices for circuits operating at different voltage levels.
• Route externally powered relay circuits according to the applicable cabinet wiring and electrical safety requirements.
• Check the connected load’s startup or inrush current against the specified 10 A maximum transient condition.
• Do not use the 0.5 A module rating as a basis for continuous operation above the stated output rating.
• Verify terminal identification and polarity against the applicable Honeywell system documentation before energizing the circuit.
• Inspect wiring and termination points before applying field power.
