mADC Output

Connections are made for current outputs 1 or 2 as shown below. 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 - 20 mADC or 0 - 20 mADC. If dual current outputs are both used,
connect the returns to terminal 5.

Position Proportioning Output
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
assigned 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.
