Features

Inputs
  • 16 isolated inputs, 24 V, incl. 14 interruptible
  • Voltage reversal protection
  • All inputs are filtered
Outputs
  • 16 isolated outputs, 10 to 36 V
  • Output current per channel 500 mA
  • At Power-on, the outputs are reset to “0”
  • Timer-programmable watchdog for resetting the outputs to “0“
  • Diagnostic report through status register in case of short-circuit, overtemperature, voltage drop or watchdog
  • Short-circuit current for 16 outputs ~ 3 A typ.
  • Short-circuit current per output ~1.5 A typ.
  • Self resetting fuse (electronic fuse)
  • Overtemperature and overvoltage protection
  • 24V power output with protective diodes and filters
  • Output capacitors minimise electromagnetic emissions
  • Voltage supply screened through a protective circuitry
  • Interrupt triggered through watchdog
  • Address range freely configurable through DIP switches, 8-bit/16-bit access
Safety features
  • Optical isolation 1000 V
  • Creeping distance IEC 61010-1 (VDE411-1)
  • Protection against fast transients (Burst), overvoltage, electrostatic discharge and EMI
  • Separate ground line for the inputs and the outputs
  • Shut-down logic when the external supply voltage drops below 5 V.
Applications
  • PLC connection
  • Control of industrial PC-based process
  • Industrial measurement
  • Acquisition of sensor data
  • Signal analysis
  • Machine interface
