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) are
4 - 20 mADC. With the EA option, they can be selected for either 4-20 or 0-20 mADC.

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.
