6.3 Operating from an external Power Supply
The external power connector is a 2mm power jack located on the rear of the unit. This
input can accept either AC or DC power and is thus polarity independent.
The unit requires 13VDC to 25VDC, when operating from external DC power.
The unit requires 12VACrms to 25VACrms, when operating from external AC power.
In either case the unit can draw up to 50mA when the backlight is on and supplying cur-
rent loop output. The power input is protected with a 250mA fuse.
The power input is isolated from the sensor and case, however as a sefety precoution,
there is a 1M shunt to prevent electrostatic buildup and discharge.
