Description
The name SERVICE is an amalgam of "serial variable interface." It is a line of universal interfaces with digital inputs, digital outputs as well as analog inputs and one RS232 serial connector. The interfaces can be connected in cascade to get more in- and outputs. Depending on the model it is best used for controlling fischertechnik -construction-kits, motors, lamps, relays, solenoids push-buttons switches and serial devices like receipt- or barcode printers. The difference between all three designs is shown in the table below:
