Input/Output (I/O) Connections and Wiring

The I/O port responds to switch closures or voltage level (high/low) changes, or can be used for

logic-level outputs.

You can connect up to eight devices to the I/O connectors (port 16). A contact closure between

GND and an I/O port is detected as a Push. When used for voltage inputs, the I/O port detects a low

(0-1.5 VDC) as a Push, and a high (3.5-5 VDC) signal as a Release. When used for outputs, the I/O

port acts as a switch to GND and is rated at 200 mA @ 12 VDC.

The PWR pin (+12VDC @ 200 mA) is designed as a power output for the PCS2 or VSS2 (or

equivalent). The GND connector is a common ground and is shared by all I/O ports. The following

table lists the wiring specifications for the I/O connectors.
