This terminal can be used to:
● read out the measuring signal,
● perform an isolated evaluation of the state of the switching function and error monitor-
ing,
● switch the high-vacuum measuring circuit on and off (only with the cold-cathode trans-
mitter PTR 225).
Dangerous contact voltage
Voltages above 30 V AC or 60 V DC are deemed to be dangerous in the event of contact
in accordance with EN 61010.
 Only apply a grounded protective extra-low voltage (PELV).
 Connect peripheral components with a shielded connecting cable (electromagnetic
compatibility) to the CONTROL terminal on the back of the device.
Pin assignment and contact positions
The pins on the 15-pin sub-D connector are assigned as follows:

1 Analog output -5 ... +13 V DC
2 Analog output GND
Switch function 1
