TTL or open collector outputs can be used for driver connection. Use TTL if driver takes +5vdc, or open collector if driver takes +12vdc or +24vdc signals. Open Collector Jumper position changed Output terminal for general purpose These outputs are open collector In this terminal, can be connected relay, led or lamps, alarm, etc.
Select Jumper for OUTPUT port_2 Use TTL if driver takes +5vdc, or open collector if driver takes +12vdc or +24vdc signals. OPEN COLLECTOR Jumper position changed DRIVER DISCONNECTION JUMPERS Set the jumper to use the driver disconnect detection feature that may be available on the C34 board.
