RELAY connector (male)
8-channel single-pole single-throw relay ports
Each relay is independently controlled
Supports up to 4 independent external relay devices
Channel range = 1-8
Each relay can switch up to 24 VDC or 28 VAC peak @ 1 A
One 8-pin 3.5mm male connector provides relay termination
I/O Port
The I/O port (port 22 on the NCITE-813AC) is a 6-pin 3.5 mm male connector used for connecting logic-level outputs. The I/O
port responds to either switch closures, voltage level (high/low) changes, or it can be used for logic-level outputs.
Each port is capable of being used as an input or an output.
FIG. 43 displays the I/O port for the NCITE-813AC.
FIG. 43
I/O ports
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 NCITE-813AC can use up to 4 I/O ports
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 1-4.
The input impedance on the I/O port is 22k.
Wiring and Device Connections
Relay Port
The relay port (port 21 on the NCITE-813AC) is an 8-pin 3.5 mm male connector used for connecting external relay
devices. You can connect up to 4 independent external relay devices on the NCITE-813AC. When a relay is “OFF”,
terminals A and B are open-circuit. When a relay is “ON”, terminals A and B are shorted together.
Relay Connections
Use connectors A for common and B for output (FIG. 42). Each relay is isolated and normally open.
A metal connector strip is also provided to common multiple relays.
In the above table, pin 1 is located on the right side of the port, and the pinouts count up to the left.
