Description
Overview
The Böning AHD 514 A manages diesel-engine starting, stopping and operating alarms, including automatic overspeed shutdown, with configuration for different engine series.
Operation and integration
Signal processing combines a galvanically isolated speed input with six 4–20 mA/binary channels, six Pt 100/Pt 1000/binary channels, two wire-break-monitored binary channels and eight control inputs for functions such as remote start/stop, acknowledgement and overspeed testing. Two additional binary inputs monitor the fuse and alternator.
Key features
- Eight potential-free 6 A relays for starter, engine control and alarm tasks
- Two 8 A stop transistor outputs with wire-break and short-circuit protection
- One analogue output configurable as 4–20 mA, 1–5 V DC or 2–10 V DC
- 24 V DC +30%/−25%
- 10,000-entry alarm/event memory readable with PC software
- Two CAN interfaces for AHD 514 S, AHD 514 OP and external alarm equipment
- RS232 9-pin Sub-D for diagnostics, logs and firmware
- One optocoupler serial input and two serial outputs
- Pluggable terminals
- IP20 rail-mount housing
