Power Supply Connections - Xytronix Research & Design ControlByWeb X317 User Manual

Installation and Connections
● Make sure wires are properly attached to the terminals and that the terminals are tight!
● Do not route signal cables in the same conduit or raceway with AC power lines feeding motors,
solenoids or other electrically noisy loads. Long cable runs are susceptible to EMI and interference,
keep cable runs as short as possible
● It is recommended that the load (device to be controlled) not be connected to the X-317™ until after
the X-317™ has been configured and tested. By doing this, wiring and configuration mistakes will not
cause the load device to turn on unexpectedly.

2.5.1 Power Supply Connections

The X-317™ requires power for its internal logic circuits. Connect a 9-28 VDC power supply to the Vin+
and Vin- terminals. Note that a regulated power supply is recommended, such as a wall-mount AC-DC
adapter. Verify that the adapter is rated for the operating current of the X-317 (See Appendix F:
Specifications for current requirements.) Multiple X-317 units may be connected to a single power
supply by connecting the power supply input terminals in parallel. The power supply must have a high
enough current rating to power all units connected.
