Digital Input Card with Galvanic Isolation


DIC122 Digital Input Card with Galvanic Isolation

•    32x digital/frequency input channels
•    Single-wire or two-wire connection of signals
•    Frequency measurement via any channel
•    Generation of the event hardware interrupts at inputs
•    System bus: 8 bit ISA bus
•    Delay of input signals: 25 μs
•    Frequency measurement via any channel
•    Isolated voltage source of:
    +12 V for potential-free contacts (isolation 1000 V)
•    Optical isolation of inputs between channels: 500V
•    Optical isolation of inputs between a channel and the “ground”: 1000 V
•    Programmed time interval for de-bouncing for inputs
•    Software compatibility with DIC112
•    Programming of interrupts
•    Operating temperature range: –40…+85°С

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.
