SSU-MR-311/T SPACE AGE

Product Overview

The Space Age Electronics SSU-MR-311/T is a low-voltage track-mounted control relay designed for advanced system interconnectivity in sensitive electronic applications. It features SPDT contacts and operates with trip currents ranging from 2.5–27.3mA and input voltages from 5–27.3VDC, making it ideal for low-power control environments. The relay supports dual input functionality (trip and host), both of which are polarity sensitive, diode protected, and opto-isolated to prevent interference between connected systems. Jumper-selectable LO and HI ranges allow optimization of power consumption based on application requirements. Its modular, snap-apart design and integrated LED status indicator provide flexibility, easy installation, and clear operational visibility.
