Full opto-isolation to computer |
| To enable a computer to communicate with the outside world, it is usually fitted with a keyboard, a display and perhaps a mouse. If however, it is to be used in control applications, or certain control functions are to be carried out, then an interface is needed. This Computer Interface Board excels in its simplicity of use and installation. |
| The connection to the computer is optically isolated, so that damage to the computer is not possible. The interface is controlled using TURBO PASCALTM~@ procedures |
| The interface itself has 16 optically isolated digital connections, which can be freely chosen as either inputs or outputs (e.g., 6 inputs and 10 outputs) according to how they are set up by the user. In addition, there are eight analogue outputs with 6-bit resolution, one analogue output with 8-bit resolution, and four analogue inputs of 8-bit resolution. If more digital outputs are required, then the analogue outputs can be used by setting to minimum or maximum output voltage. If there are too few inputs, then the analogue inputs may be used. In this way it is very simple to track the state of a rotating switch by connecting in a different voltage for each switch index position. |
| Please note that these extra input and output channels are not optically isolated. If this capacity is still not sufficient for a particular application, then up to four interface boards can be connected together (one master and three slaves), such enormous potential exists. |
| The interface can be used with many other Velleman kits such as K6714, K6710, K6711, K2607, K2633 and K2634. |
