Enova DVX-315xHD & DVX-215xHD All-in-One Presentation Switchers - Instruction Manual
RELAYS
You can connect up to eight independent external relay devices to the Relay connectors on the device. When a relay is "OFF",
terminals A and B are open-circuit. When a relay is "ON", terminals A and B are shorted together. The 315x DVX models feature
eight connectors. The 21xx DVX models feature four connectors.
FIG. 46 displays the RELAYS connectors on the DVX-3150HD-SP.

RELAYS Connectors
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. (4 on 21xx DVX models)
Channel range = 1-8 (1-4 on 21xx DVX models)
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. (Only one 8-pin connector on 21xx DVX
models.)
Port 8 on 315x DVX models. Port 4 on 21xx DVX models.
I/O
The I/O port (FIG. 47) responds to switch closures and voltage level (high/low) changes, or can be used for logic-level outputs.
FIG. 47 displays the I/O port on the DVX-3150HD-SP.
FIG. 47
I/O Connectors
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 (1-4 on 21xx DVX models)
One 10-pin 3.5mm mini-Phoenix (female) connector provides I/O connection. (One 6-pin connector on 21xx DVX models.)
Port 17 on 315x DVX models. Port 9 on 21xx DVX models.
