12V DC
1.2 W
3 Audio In Unbalanced, 1.4Vp-p, 1Vrms, terminal block -
4 Audio Out Unbalanced, 1.4Vp-p, 1Vrms, terminal block -
5 Digital Output 1
Uses an NPN transistor with the emitter connected to
the GND pin. If used with an external relay, a diode
must be connected in parallel with the load for
protection against voltage transients.
100 mA
24V
6 Digital Output 2
Uses an NPN transistor with the emitter connected to
the GND pin. If used with an external relay, a diode
must be connected in parallel with the load for
protection against voltage transients.
100 mA
24V
7 Digital Input 1
Connected to GND to activate, or leave floating (or
unconnected) to deactivate.
30V DC
8 Digital Input 2
Connected to GND to activate, or leave floating (or
unconnected) to deactivate.
30V DC
