RELAYS (PORT 8)
You can connect up to eight independent external relay devices to the Relay connectors on the device
(FIG. 37). When a relay is "OFF", terminals A and B are open-circuit. When a relay is "ON", terminals A and
B are shorted together.

Each relay is isolated and normally open.

A metal commoning strip is supplied with each device to simplify the connection of multiple relays
to a common reference if needed.

8-channel single-pole single-throw relay ports

Each relay is independently controlled

Supports up to 8 independent external relay devices

Channel range = 1-8

Each relay can switch up to 24 VDC or 28 VAC peak @ 1 A

Two 8-pin 3.5mm mini-Phoenix (female) connector provides relay termination
I/O (PORT 17)
The I/O port (FIG. 38) 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.

The input format is software selectable with interactive power sensing for IR ports.

Channel range = 1-8

One 10-pin 3.5mm mini-Phoenix (female) connector provides I/O connection
