6.4.7 TERMINALS P1-P2 OR P5-P6: POWER SUPPLY – TYPE PD/PX
Power connection differs with or without Type OR
● Without Type OR, power should be connected to MEM terminals P1 and P2.
● With Type OR, power should be connected to RSM terminals P5 and P6.
Connect an external 9-27 VDC power supply to these terminals.
When power is applied to these terminals, discharge of the (optional) internal battery will be
disabled. See also Section 6.4.3: Electrical ratings[»41].
6.4.8 TERMINALS P3: SENSOR SUPPLY - TYPE PD
This terminal may be used for sensor supply. See Section 6.4.4: Voltage selection sensor supply[»41]
for relevant information.
Power requirements for sensor supply P3:
● 8.2 V sensor supply requires 9-27 V
● 12 V sensor supply requires 13-27 V
● 24 V = V-input – 1V (max 27 V)
