Isolated Barrier SPD Safety Relay NEWPWR-Focus Security and Stability on Industrlal measurement and control signals

NPEXA-CM177

Millivolt input isolated barrier, it transfers the millivolt signals from a hazardous area to a safe area. It needs an independent power supply. The input, output, and power supply are galvanically isolated from each other. It has the function of setting over range output when the input is disconnected.

Connect the rail BUS base, external power is introduced through the terminal block of the base. If a redundant power module is selected, this terminal can be left unselected.

Protect the exposed bus and split the combination as needed.

For fixed position, standard 2 sets

Material: metal iron, used for rail load-bearing reinforcement, standard 2 pieces
