Digital I/O module DC-DI

4 digital inputsDIN railrobust

The digital inputs of HiTec Zang ASs may be used for frequency measurement in addition to their use for the pure recording of binary conditions (in/out). In NAMUR mode, short circuit and wire break can be detected. • Frequency measurement • Edge detection • Counting input • Period length measurement • Pulse duration measurement • Inputs with switchable NAMUR-compliant level detection system • Status LED for each channel, displays the binary condition or errors • Galvanic separation between inputs and bus • Signal : Input level ±35 V, 24 V logic (NAMUR-compliant level) • Connection type : Plug-in connectors with push-in spring connection or optionally pluggable screw terminals. • Digital counting function : 32 Bit • Frequency measurement : 0.5 Hz…100 kHz • Operating voltage : 24 V (18…30 V), supply via bus • Power consumption : max. 55 mA • Dimensions (HxWxD) : 99.5 x 22.5 x 114.5 mm • Working temperature : 0…+60 °C • Storage temperature : 0…+65 °C • Humidty : 90 %, not condensing • For the recording of : Proximity initiators, switch contacts, speed measurement, level switches, pressure switches, digital status signals of devices, etc.
