Description

Overview

The Böning AHD504 A starts, stops and monitors diesel engines with automatic overspeed shutdown and engine-series-specific configuration.

Operation and integration

Its inputs comprise one isolated speed channel,11 configurable analogue channels, three wire-break-monitored binary channels and six control inputs for functions such as remote start/stop, acknowledgement and overspeed testing.

Key features

  • Four potential-free 3 A relays
  • One 8 A wire-break-monitored, short-circuit-protected transistor output
  • One 32 V/25 mA transistor output
  • 24 V DC +30%/−25%
  • Two CAN interfaces with optional external J1939 connection
  • RS232 9-pin Sub-D for diagnostics/firmware
  • One optocoupler serial input and one serial output
  • Pluggable strips
  • IP20 standard-rail housing
