Delta DVP-SX Instruction Sheet page 4

Installation of the DIN rail:
The DVP-PLC can be secured to a cabinet by using
the DIN rail that is 35mm high with a depth of 7.5mm.
When mounting the PLC on the DIN rail, be sure to
use the end bracket to stop any side-to-side motion
of the PLC, thus to reduce the chance of the wires
being pulled loose. At the bottom of the PLC is a
small retaining clip. To secure the PLC to the DIN rail,
place it onto the rail and gently push up the clip. To
remove it, pull down the retaining clip and gently pull
the PLC away from the DIN rail.

3.2 Wiring Notes
 Power Input Wiring
DVP-SX series input power supply is DC input. Please take a note of listed items when operating DVP-SX
Series.
1. Please make sure the power is at terminals 24VDC and 0V (power range is 20.4VDC ~ 28.8VDC). When
voltage is lower than 20.4VDC, PLC will stop operating, all outputs will turn Off and ERROR LED will flash
continuously.
2. If the power-off time is less than 10ms, the PLC still operates unaffectedly. If the power-off time is too long or
the power voltage drops, the PLC will stop operating and all the outputs will be Off. Once the power is
restored, the PLC will return to operate automatically. (There are latched auxiliary relays and registers
inside of the PLC, please be aware when programming.)
DC Input Type
 Safety Wiring
Since the PLC is in control of numerous devices, motion of either one device could affect the motion of other
devices, therefore the breakdown of either one device would consequently be detrimental to the whole auto
control system, and danger will thus be resulted. Please use the recommended wiring below for the power
input:

1. Please use 26-16AWG (0.4~1.2mm) wiring (either single or multiple
core) for I/O wiring terminals. The specification for the terminals is as
shown on the left. PLC terminal screws should be tightened to between
2.00 kg-cm (1.77 in-lbs). Use 60/75°C copper conductor only.
2. I/O signal wires or power supply should not run through the same
multi-wire cable or conduit.

When installing the DVP series PLC,
make sure that it is installed in an
enclosure with sufficient space (as
shown below) to its surroundings so as to
allow heat dissipation.
