2.2. Digital inputs

SCOM-100 has 4 built in digital inputs, which can be expanded by the DIO-42 expansion modules. The digital inputs are wired by means of screw terminals.

The digital inputs can be driven either by switches or transistors (open collector stages). Transducers with

push-pull output are also applicable.

Note: Output voltages higher than +5V or negative voltages (lower than GND) will be clamped from the comparator input protection zener. The impedance of the input circuit is, in this case, 4.7K. An external transducer with 24V output must be capable of driving a current of 5 mA.
