Installation
Two Position Air Actuator Connections
The SVI can be used to control up to four Valco two position air-actuated
valves by connecting the SVI to the Valco Digital Valve Interface (DVI). The
two position electric actuator cable can be adapted to control a DVI using
this procedure:
1. Use a wire cutter to remove the plastic Molex connector from the SVI
connecting cable.
2. With a wire stripper, remove insulation from the red, blue, and black
wires in each of the DVI ribbon cables and the corresponding SVI ribbon
cable.
3. Use solder or crimp-on connectors to join the DVI ribbon cable to the SVI
ribbon cable as shown in the table below.
SVI Control of Other Electrical Devices
NOTE: The following information is not intended for users unfamiliar with low
power digital circuitry and proper isolation techniques.
The V1 PosA output on the SVI has special capabilities. While all other
two position outputs are transistor devices with 30 volt 50 milliamp (open
collector) outputs, the YELLOW wire (pin 4 of the Molex connector) on the
V1 output is a relay contact closure to ground. It can be used to drive loads
of up to 48 volts at 1/2 amp.
Additionally, the ground reference brown wire (pin 3 of the Molex) can be
jumpered on CO12 on the SVI main board for a 12 VDC output which is
sufficient to power small solenoids or other devices of up to 100 ma con-
tinuous current. (Or 200 ma on short duty cycle applications.) See Drawing
22110, page 14 for detailed information.
