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.
