Relay 1-B
The Express 2 I/O connector contains one opto-isolated trigger input
and one relay connection.
Pins 1 and 2 are the opto-isolated input, providing 2500VRMS
isolation. To trigger, apply positive voltage to pin 1 and apply negative
or ground to pin 2. The trigger voltage should be 3.5VDC to 12VDC,
1.4mA minimum. You may connect directly to a 12VDC alarm system,
current-providing door sensor, etc. but the polarity must be correct or
you risk the possibility of false triggers. Sensors such as simple open/
closed switches cannot be used without a pull-up voltage to provide the
[email protected] minimum.
Pins 3 and 4 are the relay, which can handle 2A @ 28VDC. It is
