I/O Connections
The actual I/O connections are located on a 25-position DB25-type female connector
located at the bottom of the module. A separate three-conductor removable screw
connector provides 24VDC power to external devices.
The inputs are labeled I/O1, I/O2, I/O3, and so forth. Each input/output occupies a single
position of the connector. Five signal ground pins are supplied as well.
The diagram below indicates where each input number is located on the module.
