Product Description

PHOENIX Relay module 2901585 UM-2KS50-RM/16MR/24/SDV144/SO

Product Description: PHOENIX CONTACT UM-2KS50-RM/16MR/24/SDV144/SO 

16-Channel Relay Output Module

High-Density, Electromechanical Switching for Maximum Flexibility and Isolation

The PHOENIX CONTACT UM-2KS50-RM/16MR/24/SDV144/SO is a versatile and robust 16-channel relay output module from the industry-leading INLINE and PHOENIX Relay series. This module is engineered to provide a powerful interface between your control system (e.g., PLC, controller) and a wide variety of high-power AC/DC loads.

Its core component is 16 built-in electromechanical relays, offering complete galvanic isolation between the sensitive control circuitry and the switched load circuit. This isolation protects your controller from voltage spikes, electrical noise, and potential faults in the load side, making it an indispensable component for reliable automation in harsh industrial environments.

Typical Applications

This module is the ideal solution for switching and controlling a diverse range of industrial loads, including:

• Solenoid valves, contactors, and motor starters

• Heating elements, fans, and pumps

• Lighting systems (AC and DC)

• Signaling devices like horns and lamps

• Any application requiring control of a high-voltage/current circuit with a low-voltage DC signal.

Why Choose This Module?

• Ultimate Flexibility: The changeover (SPDT) contacts allow for a wide range of switching configurations (NO or NC operation) for various AC and DC loads from a single module.

• Superior Isolation: The 4 kV isolation ensures maximum protection for your valuable control equipment from load-side electrical disturbances.

• High Density: 16 relays in a single module save crucial space in the control cabinet.

• Hybrid Connection: The combination of a pluggable SDV 144 terminal for control signals and screw clamps (SO) for load power optimizes both installation speed and connection reliability.

• Proven Durability: Built to PHOENIX CONTACT's stringent quality standards for long-term reliability in demanding conditions.
