PHOENIX EMG 12-REL-KSR-24-1 Relay Module

Product Dimensions：

The Phoenix Contact EMG 12-REL/KSR-24/1 (Order Number: 2949240) is an electromechanical interface relay module designed for industrial control applications. It provides safe electrical isolation and signal conditioning between low-voltage control circuits (like PLCs) and medium-to-large field loads.

Product Detailed Description

The EMG 12-REL/KSR-24/1 features a soldered-in miniature switching relay built into a compact, 12 mm wide housing. Equipped with a Silver Nickel (AgNi) contact material, this monostable relay is highly optimized for switching medium to large electrical loads reliably over long operating cycles. It features integrated input protection circuitry, making it highly resilient to polarity errors and voltage transients.

Technical Parameters

Product Advantages

• Integrated Universal Protection: Thanks to its built-in bridge rectifier, the module can accept both AC and DC control voltages on the coil side, simplifying part management and protecting against accidental polarity reversal.
• Space-Saving Design: At only 12 mm wide, this module optimizes cabinet space and can be stacked seamlessly with zero spacing between adjacent modules.
• High Safety Isolation: A 4 kV test voltage rating between the coil and contact side ensures robust galvanic isolation, shielding delicate PLC inputs/outputs from high-voltage field surges.
• Immediate Status Feedback: A highly visible yellow LED provides an immediate visual status indicator of the relay’s coil excitation, reducing troubleshooting time.

Important Considerations & Precautions

• Load Minimums: The Silver Nickel (AgNi) contacts are designed for medium to large loads (minimum 12V, 100mA). Avoid using this specific module for ultra-low power signal switching (such as dry circuits or high-impedance PLC inputs), as the contact material requires a minimum load to pierce surface oxidation.
• Soldered-In Relay: The internal miniature relay is directly soldered to the PCB. If the contacts reach their end-of-life or burn out due to a short circuit, the entire module must be replaced rather than just a plug-in cartridge.
• EMC Notice: This is a Class A product. In domestic environments, it may cause radio interference, so appropriate shielding or filtering precautions should be taken if used outside industrial panels.

Product Applications

• PLC/DCS Output Interfacing: Amplifying low-current transistor or digital outputs from control systems to drive heavy-duty field components.
• Actuator Control: Operating small motors, solenoid valves, contactor coils, and heating elements in automated systems.
• Electrical Isolation: Functioning as an isolation barrier between independent field networks or systems operating on mismatched ground potentials.
• Industrial Panel Building: General signal logic coupling across manufacturing plants, water treatment facilities, and assembly lines.
