Wiring and Device Connections

RELAYS (PORT 4)
You can connect up to four independent external relay devices to the Relay connectors on the device.
Connectors labeled
A are for Common and B are for Output (FIG. 17).

Each relay is isolated and normally open.
I/O (PORT 9)
The I/O port (FIG. 18) responds to switch closures and voltage level (high/low) changes, or can be used for
logic-level outputs.

A contact closure between the GND and an I/O port is detected as a Push.

When used for voltage inputs, the I/O port detects a low signal (0 - 1.5 VDC) as a Push, and a high
signal (3.5 - 5 VDC) as a Release (
this I/O port uses 5V logic but can handle up to 12V without
harm) .

When used for outputs, the I/O port acts as a switch to GND and is rated for 200mA @ 12 VDC.

The PWR pin pr12 VDC @ 200 mA and is designed as a power output for the PCS Power
Current Sensors, VSS2 Video Sync Sensors (or equivalent).

The GND connector is a common ground and is shared by all I/O ports. A common ground is
shared with I/O ports 1 - 3.
The following table provides wiring requirements for the I/O port:
When wiring the 422/485 connections, do not use pre-made 9-wire cable or connect
the wire in the cable to any connection that will not be used by the DB9 serial port.
Only use wiring that connects the needed pins.
