mADC Output
Connections are made to current outputs 1 and 2 as shown. Connect the positive lead to
terminal 6 for Output 1 or terminal 7 for Output 2, the negative leads connect to terminal 5.
Current outputs will operate up to 650 ohms maximum load. The current output(s) can be
selected for either 4-20mADC or 0-20mADC (if EO option is present).

Position Proportioning Control
The relay and slidewire feedback connections are made as illustrated below. The relay
assigned to Output 1 will be used to drive the motor in the open direction and the relay
asssigned to Output 2 will be used to drive the motor in the closed direction. The minimum
slidewire feedback resistance is 135 ohms, the maximum resistance is 10K ohms.
