Digital inputs
The digital inputs can be used for external control. A batch run can be started or stopped via these
inputs, or the inputs can prevent a new batch from starting. In addition, the time can also be
synchronized.
10.0.2
Output
Current/pulse output
(optional)
This output can be used either as a 0/4 to 20 mA current output or as a voltage pulse output. The
output is galvanically isolated (500 V testing voltage towards all other inputs and outputs).
Current output
Pulse output
2 x relay output
The relays are designed as NO contacts. The output is galvanically isolated (1500 V testing voltage
towards all other inputs and outputs).
2 x digital output (open
collector, optional)
The two digital inputs are galvanically isolated from one another and from all the other inputs and
outputs (testing voltage: 500 V). The digital outputs can be used as status or pulse outputs. The open
collector outputs are particularly suitable for a high number of switching cycles since, in contrast to
relays, these outputs are non-wearing.
Auxiliary voltage output
(transmitter power supply)
The auxiliary voltage output can be used to power the transmitter or control the digital inputs. The
auxiliary voltage is short-circuit proof and galvanically isolated (500 V testing voltage towards all
other inputs and outputs).
