1. I/O connect board controls 24 input terminals and 16 output terminals.
2. Output control is by 0V output.
3. An INPUT can be of NPN type or PNP type.
4. When NPN and PNP are in use at the same time,
(1) NPN the input voltage at I is 0V.
(2) PNP the input voltage at I is 24V.
5. Input current at I: 6mA
6. Output current at O: 100mA

1. Max. current for each output of the PCB is 1A
2. For a max. current > 1A, use other relays.
Contacts on the RELAY adaptor board are dry contacts
