URRHH Power module

URRHH Power module
Modules are available in two voltage ranges, with or without redundant power options. Low range (LO) operates at nominal voltages of 24 to 48V (DC only), while high range (HI) operates at nominal voltages of 125 to 250V (DC and AC). The power module can supply power not only to the relay, but also to the dry contact input connection. Its internal fuse rating is 4A/250V.
The power module also has a self-test component that automatically evaluates the health of the power module. The primary and secondary tests used to ensure the integrity of the device can assess proper hardware functionality and cut off power to the PSU in the event of a serious failure.
Power modules are often used in industrial automation control systems, such as PLC (programmable logic controller), DCS (distributed control system) and HMI (human-machine interface), etc., for connecting and managing sensors, actuators, switches, etc., to achieve automatic control of industrial processes.
