Properties

SM 422; DO 32 x DC 24 V/0.5 A has the following features:

32 outputs, isolated in a group of 32
Power supply in groups of 8 channels.
A supply group always consists of 8 neighboring channels, starting from channel 0. Channels 0 to 7, 8 to 15, ... 16 to 23 and 24 to 31 each form a supply group.
Each of these supply groups can be switched off separately by disconnecting L+; however, you must remember the common ground connection.
Output current 0.5 A
Rated load voltage 24 V DC

The status LEDs indicate the system state even if the front connector is not connected.
