ODOT CT-2754 4-Channel Relay Output Module – 3A/30VDC/90W (with RC & Flyback Diode)


Key Features

  • 4-channel relay normally on output
  • 4 LED channel indicators
  • Low on resistance (≤100mΩ)
  • With isolation between channels
  • Built-in unidirectional (freewheel diode) FWD, built-in RC circuit
  • Resistive and inductive loads can be connected


The ODOT CT-2754 is a 4-Channel Normally Open Relay Output Module with 4 LED channel indicator lights. It features low on-state resistance (≤100mΩ), isolation between channels, built-in unidirectional freewheeling diodes, and an internal RC circuit. This module shares similar functionalities with the CT-2738 model, designed for use with a 24VDC voltage specification. Like the CT-2738, it cannot be connected to alternating current (AC). However, in addressing the CT-2738′s moderate load capacity, this module reduces the number of channels to four and selects higher-rated relay contacts, achieving a load capacity of 3A, suitable for the majority of 24VDC driving requirements.

The ODOT CT-2754 can be easy integrate with SCADA, PLC, PAC and PC based software systems for a wide range of industrial automation, measurement and process control applications.
