Basic method of operation

The board will add the coins that have been inserted up to the programmed amount. Once that amount has been reached, the board will activate in one of three ways.

Operating Modes

Pulse Mode:

On reaching the required value, the board will pulse the relay. This mode can be used to simulate a button press, in order to activate a equipment with a timed cycle like a massage chair, or to pulse a solenoid on a dispense mechanism.

Latching Mode:

On reaching the required value, the board will activate the relay until it receives a reset signal. This mode could, for example, be be used to run a dispensing motor or operate an electronic door lock for access control .

Timer Mode:

On reaching the required value the relay will activate for a preset amount of time. This is ideal for selling long timed events like the light over a snooker table and children’s rides or short accurate lengths of time as needed for filling a cup full of water.

Please note that this requires a separate software version which must be specified when ordered.

Customised Software

Everyone’s needs are different and even if your needs are not quite what we have described above, we can adapt our software to meet your needs.

Technical Details

Power Supply

The board can be powered from 230VAC or 12VDC making it easy to tap into the power

Relay Output

The output relay can be connected for both normally open or normally closed configuration. The relays contacts are rated to switch up to a maximum of 230VAC and 8 Amps.

Coin Mechanism

The board can use with either a mechanical coin mechanism or an NRI G13.7000 electronic coin validator if you require a more complex system.  It has six different coin inputs for use with coins and/or tokens of any currency. The G13.7000 can be supplied programmed for any currency or tokens on request (standard g13 supplied programmed for the following 6 coins 5p, 10p, 20p, 50p, £1 and £2).

The board also has an input for telling the board to inhibit the coin validator to ensure it rejects any other coins inserted while the input is present. This can be used for wiring a sold-out switch to the board, stopping customers from being insert money after the machine has sold out of product.

User Set Price

The price of the product can be set to any value using switches on the PCB.
