Revision 3.01. March 15, 2003

Applications for vending time from 30 seconds to 8 minutes per bank note is accomplished with the VCB-1T Timer Board. Optional time versions for 60 seconds to 16 minutes, or 2 minutes to 32 minutes are also available.   Time vends can be accumulated in "escrow" for many cycles of minutes, hours or even days.  Ideal for connection to the USA Technologies G7 or G8 e-Port MDB connector for timed vending.

Optional use of the VCB-1 series vending controller board is for vending of products such as cards with a card dispenser mechanism or a coin payout hopper assembly with +12 or +24 power input.  Many other applications are used for the VCB-1 vending controller board.

The VCB-1T Timer Board accepts dry relay contact closure pulses from a bill acceptor as input. Each pulse input from the Bill Acceptor or Coin Mechanism represents a Time Unit of seconds to dispense. The basic time interval in Revision 3.01 is thirty (30) seconds to eight minutes. 

Four DIP switches on the board must be set before power-up to define how many basic time intervals can be purchased for one pulse form the Bill Acceptor. One input pulse is usually equal to one dollar ($1.00).

Using the four DIP switches allows setting up to a maximum of 16 basic time intervals to equal one Time Unit. The following table gives the settings and possible Time Unit set at power-up.

Note: A five dollar bill would give five pulses, so whatever the Total Time Set is multiplied by five.  At any time, more bills can be inserted to add to the Total Escrow Time.

The bill acceptor pulses must be at least 20 Msec ON and 20 Msec OFF. So the standard fast pulses for pulse bill acceptors at 50 Msec ON and 50 Msec OFF will function to specifications.

A green LED will flash during the last time cycle to indicate that more money should be inserted and that the time cycle is about to end.  A continuous illuminated green LED indicates that more than one vend cycle is in the escrow in a count down condition.  As an example, a maximum escrow of 4,000 of the 8 minute cycles could accumulated.

Hardware configuration is as follows:

Requires a +12 volts DC power source at a minimum of 1/2 amp to power the VCB-1T Vending Access Time Control Board.    Connection of the power source is on pins 1 for the ground and pin 2 for the +12 volts DC to the 1x12 JST connector.  The pin numbers are indicated on the female connector.

The "Trigger Pulse" or "Vend Pulse" is on pin #4.  This pin #4 is sitting high and must be taken low by a closure to the pin #1 of the JST 1x12 connector.

Output to the host device is a +12 volt DC & ground from the "output" 2 pin Molex connector (Motor).

A 12 volt DC counter can be connected to the bill acceptor for accountability of cash pulses received.  Optionally...a coin mechanism can be connected in lieu of a bank note acceptor.   Each coin inserted will accumulate vend cycles in escrow.  Example is 1 Euro coin inserted for a 8 minute vend cycle for a car wash application.   Combination coins and bank notes can be interfaced to the VCB-1T for input of cash value.

A green LED with a 1K resistor in series with the LED can be connected to the output connector in parallel with the +12 volt & ground output (motor).   This green LED indicator would provide a signal to the vending patron that the time vend cycle is in operation.

Customer application for high voltage such as 110 volts or 220 volts should use a power relay with the proper amperage contacts with a 12 volt coil.

Note:  Pulse Output for the Heavy Duty 20 - 40 Amp Relay is from the Motor Output 1x2 Molex Connector.  This output signal is held "latched" on the relay #1 for the total vend time cycle.

  1. An alternate version identified as A-IM is available for the Companion Massage Chair Vending Controller.  We provided the delay of 3.5 seconds on relay #2, then added the new circuit for 1 second for a 3rd +12 volt common Bosh single pole relay available in the UK at any Auto parts store or Electronics store.   This requirement is for the later version massage chairs that have a selection for the foot or leg massage.
  2. We then changed the VCB-1T signal output that turns on the lamp of the push button from "on" or "illuminated" for the full vend time cycle" to a "1 second" time cycle after the #1 and the #2 relays are energized.  We also change the wiring of the circuit.
  3. The push button has a orange wire and a blue wire connected to the lamp circuit of the push button.  Remove these 2 wires from the push button.
  4. A +12 volt single pole N/O relay is required for this application  Mount this relay on the back inner wall of the Companion.  
  5. Plug the blue wire that you removed from the push button to 1 side of the +12 volt coil of the relay and the orange wire from the push button to the other terminal of the single pole +12 volt common relay coil circuit.
  6. Connect a wire from the "common" contact  and another wire from the "Normally Open" contact of the +12 volt relay.
  7. The other end of these 2 wires would go to the common male 5mm spade connector of your push button switch and the Normally Open connection.   Splice these 2 wires onto the existing black and white wires of your green switch in your push button.  This is your push button normal circuit in the keypad or wand to trigger your foot massage.
  8. Last...from the push button switch black wire and the white wire & now your new relay contacts...connect this circuit to your foot massage location in your wand or keypad.   Your vending customer can toggle in parallel with your new relay contacts for activation or de-activation of the foot massage or other selection of the wand or keypad.
  9. Last step.   Connect the +12 volt contacts of your push button to +12 volt output from your power supply that goes to the bill acceptor.   You can splice in a new +12 volt orange wire to one side of the push button and a black wire to the ground circuit.    The +12 volt DC push button will always be illuminated.
  10. This circuit is very easy for you to use and allows you to use on the Companion's for either newer model Sanyo or Panasonic massage chairs that require three (3) vend selections of the keypad or wand.
