Service USB Interfaces

Description

The name SERVICE is an amalgam of "serial variable interface." It is a line of universal interfaces with eight digital inputs, eight digital outputs as well as two analog inputs with up to 12 bits resolution 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:
