Digital output module 4 RO-SSR-255

Description

The digital output module UR20-4RO-SSR-255 uses four semiconductor switches to control up to 4 actuators, each with a maximum of 1 A at 255 V AC. The switching characteristics of the semiconductor switch have it as being closed when the voltage crosses zero and open when the current crosses zero. Each connector features a potential-free NO contact (Normally Open). A status LED is assigned to each
channel.
