    Sales & technical support

    The card is implemented in MicroPC standard, is equipped with 32-x channels and is designed for reading the states of digital signals or measuring frequency signals with voltage levels from 3.2 to 52 V. The device uses the field-programmable gate array (FPGA), which makes it possible to change processing algorithm of inputs (or diagram) without changing the topology. Channels can use a single-wire/twowire connection (with common ground). It is possible to connect signals of potential-free contact type using an internal isolated (12 V) or external (up to 52 V) power supply source. The card is hardware- and softwarecompatible with DIC112 digital I/O modules.
