EATON control relay EASY-E4-DC-12TCX1 24 VDC, 8 outputs (4 changeover) model 197214

EATON EASY-E4-DC-12TCX1 is a control relay module designed for industrial automation and control panels. The unit operates from a 24 VDC supply and provides eight outputs, including four changeover (SPDT) contacts, enabling flexible switching of control circuits and signal distribution between low-voltage logic and field devices. The compact module is intended for panel mounting and integration into relay logic, machine control and safety-related switching tasks where reliable contact switching and clear channel separation are required.

Advantages

The module offers a standardized 24 VDC coil voltage and mixed output configuration with both normally open/normally closed capability on four outputs, which simplifies wiring for multi-function control applications. Its design supports straightforward panel integration and reduces space requirements compared with discrete relays. The product provides deterministic mechanical switching behavior, clear electrical isolation between coil and contacts, and compatibility with common industrial control voltages and wiring practices.

Suitable for (tasks / use cases)

• Relay logic and ladder control circuits in machine panels
• Signal interfacing between PLC outputs and field actuators or indicators
• Distribution and switching of control circuits requiring multiple contact types
• Replacement or expansion of electromechanical relay functions in control cabinets

Key specifications

• Supply voltage: 24 VDC coil operation
• Outputs: 8 switching outputs with 4 changeover (SPDT) contacts
• Contact configuration: mixed NO/NC capability on changeover outputs
• Mounting: panel mounting suitable for industrial control enclosures
• Function: control relay for switching and signal distribution in automation systems

How to use

Install the relay module in the control panel according to local mounting and wiring standards, ensuring the 24 VDC supply is connected to the coil terminals and that load circuits are wired to the appropriate output contacts. Verify contact ratings and load types before applying power. Use the changeover contacts where both normally open and normally closed switching is required; use dedicated outputs for single-contact switching. After wiring, apply power and test each output under no-load and then under load conditions to confirm correct operation and contact wiring.

Recommendations

Follow the manufacturer's installation guidelines and safety rules for panel wiring. Verify contact current ratings and use appropriate protection (fuses, circuit breakers, suppression devices) for inductive loads. Ensure regular inspection of terminal connections and replace the module if any signs of contact wear or abnormal operation appear.
