8 I/O Module
The 8 I/O module supports 8 Field Contact Inputs and 8 Solid State Digital Outputs. Each input
requires approximately 2 mA current per input and each input is optically isolated. The digital
outputs can switch up to 5 watts per input with a maximum voltage of 63 VDC and maximum
current of 200mA. There are jumpers on the board for N.O. (Normally Open – Contact closes
on alarm) or N.C. (Normally Closed – Contact opens on alarm). In addition, there are jumpers
for selecting an address within the Input Card Rack. Connection is by screw type terminals
(1.5mm², 16 AWG max.).
