Function
Relay Contact
The contact is on a floating basis. Its setting depends
on the settings in the software.
Steady-rate signal:
passive = open relay contact
active = closed relay contact
Pulse:
Closed relay contact for at least 1000 ms
Permissible load of the relay contact: 1 A/ 24 V DC
Analog GND
Reference point of the voltage at the signal inputs.
Analog OUT
Voltage range 0 – 5 V, scalable
Analog IN
Voltage range 0 – 10 V
10 V according to maximum flow rate
Start GND
Reference point of the voltage at the signal inputs.
Start OUT
TTL output
Levels:
passive 5 V
active 0 V
Start IN
TTL input
Low active
Secure switching threshold at least 10 mA
After receiving a signal (short-circuit to ground) from
an external device, the device starts. If controlled
with software, an electronic trigger is send through
the LAN.
Error OUT
TTL output
Levels:
passive 5 V
active 0 V
Error IN
TTL input
Low active
Secure switching threshold at least 10 mA
After receiving a signal (short-circuit to ground) from
an external device, an error message appears and
the device stops.
Error GND
Reference point of the voltage at the signal inputs.
