Type PD: Sensor supply: 8.2 VDC – 12 VDC or 24 VDC (Vin P2 minus 1 V)
This option provides a supply derived from the input supply. Adjust the P3 output voltage using
switches J1 and J2 on the bottom rear of the MEM (Main Electronics Module) - see following figure.

ON ON 8.2 V DC (max. output 20 mA) 9 – 27 V DC
ON OFF 12 V DC (max. output 30 mA) 13 – 27 V DC
OFF OFF Supply voltage - 1 V DC (max output 75 mA) Up to 27 V DC
Power overload
The sensor supply is protected against a power overload but an overload may affect the functionality
of the unit (i.e. shutdown).
