6.2 External +24V-signals
The in-line uses 4 external ports to receive external machine signals. These are also being used
to connect your genuine edding accessories photocell, encoder and alarm light. The ports are
assigned as followed:
PC 1 / PC 2:
Pin 1 PNP Signal input: Send a +24V signal for print-go
Pin 2 GND Ground / earth
Pin 3 NPN Signal input: Send a GND signal for print-go
Pin 4 +24V +24 V supply voltage
If possible, please aim to switch potential-free signals. The maximum power drain of all external
connectors shall not exceed 1.5 A. You do not have to set PNP or NPN via the software, both
inputs are leading to similar results. Only do not use them in parallel at the same time. The
inputs are debounced at 3 ms.
ENC:
Pin 1 +24V +24 V supply voltage
Pin 2 ENC A Input for incremental encoder signal (HTL)
Pin 3 Rel A Relay-input
Pin 4 Rel B Relay-output
Pin 5 GND Ground / earth
The maximum power drain of all external connectors shall not exceed 1.5 A.
