Connecting Your V550-A20 To An External Device
You must supply power to the V550-A20 through the 15 pin connec-
tor at the rear of the unit. You can supply power using one of the
following two methods: using an Omron local power supply or
wiring power directly into the V550-A20 using one of your own
methods.
The V550-A20 must meet the following three requirements regardless
of the method that you use to supply power:
• +5VDC must be supplied
(range b4.85VDC and +5.25VDC @ 500 mA typical, 600 mA max.,
maximum ripple 100mV)
• Ground must be supplied
• Metal shell of connector must be grounded
Make sure the metal shell of the connector is grounded. This pro-
vides chassis ground to the unit case, and is necessary for proper
operation.
Using Omron's Power Supply For Power
You can use the Omron S82S-0305 power supply to supply power to
the V550-A20 15 pin "D" connector. Note that a UL class 2 power
supply should be used for UL approval. This power supply is shown
below:
If you use this power supply, you need to connect cable leads to the
V550-A20 15 Pin "D" connector. Use the following information to
make these connections:

If no ground is available from another source, you can connect to the
