I/O RELAY CARD

(with loopback test function)

The 38N series I/O Relay Cards easily and quickly standardize and facilitate installation of the DCS relay board.

Loopback test function simplifies startup and maintenance. The Standard Rack (Nest) model 38N can accept at

the maximum of 16 channels of inputs and outputs.

•Input and output on one card

•Output ON/OFF switch and LED indicating relay status

•Test switch provided for checking DCS operation

•Fuse provided to each channel for electromagnetic valve

•Output current capacity 3A

•Output can be jumper selectable: voltage output for electromagnetic valve or dry contact output.
