SOURCE/SINK DIGITAL I/O CONFIGURATION

The digital inputs and outputs are configured by moving two IC’s on the

control circuit board located directly behind the front panel. Be sure that the

power is OFF and then remove the top cover. The components may be

moved using a small screwdriver to pry the IC’s from the socket strips.

Select the “Source” or “Sink” location and reinstall the components. They

are not required to be set the same – one may be “Source” and the other

“Sink” to best match the required interface signals.

The optical isolator for the Digital Outputs (DO) is shown in the default

“Source” configuration.

The outputs may be switched to “Sink” by moving this IC to the alternate

location as shown below.

The digital inputs

may be

reconfigured in the

same manner.

They are also set

for “Source” as the

factory default as

shown above.

Digital Inputs

shown configured

for “Sink.”
