  • 2x CPU 16 Bit, 80C167CS, 20MHz
  • 2x1MB Flash-EPROM, 2x320kB reserved for user program (UP)
  • 2x512kB Fast SRAM
  • 2 RS-232 interfaces
  • 2 CAN interfaces
  • 16 digital inputs, positive switching, configurable to ground switching, can be used for period duration measurement too
  • 8 digital inputs, positive switching, 4 of them configurable as counter inputs or 2x A/B-counter inputs
  • 8 inputs analog, 0...10V, 12 Bit
  • 8 inputs analog, 0...20mA, 12 Bit
  • 8 PWM-outputs with current control, 1,5A, short-circuit-proof, overload-proof, can be used as digital outputs
  • 8 ratiometric outputs: - neutral position at 50% operating voltage - max. deflection in position A at 25% operating voltage - max. deflection in position B at 75% operating voltage
  • 2 analog output, 0...20mA, 10 Bit
  • 2 real-time clock
