Counter Input
The WPC-MTX transmitter supports two forms of counter input being either for a voltage free dry contact or TTL. While both inputs could be driven from independant sources, they are paralleled internally into a single pulse input. Do not apply volts to the dry contact pulse input.
There is provision for a current limited 5V@5mA output to power external devices. This current limited output is only available when external power is applied - it is not driven when the unit is running from the internal battery. This current limited output could be used to drive an external inidicator/relay that shows when external power is present or lost.
