AHD 406

Product catalog summary

General Overview: The AHD 406 is a microprocessor-controlled device designed for monitoring and controlling engines, particularly in maritime environments. It is built to withstand harsh conditions such as high temperatures, humidity, vibrations, and voltage fluctuations.

Construction: The unit comprises two electronic cards connected by threaded pins, housed in a DIN 43700 compliant casing made of impact-resistant, self-extinguishing plastic. The integrated circuits are socket-mounted for easy replacement, facilitating repairs even by non-experts. Connections are made via a 50-pole plug and ribbon cable, included in the delivery.

Functionality: Upon power connection, the device monitors up to 10 external sensors. Alarms are indicated by flashing LEDs and an external horn. Three group relays can activate alarm or control operations. The front panel includes keys for lamp acknowledgment, horn acknowledgment, lamp test, and alarm test, allowing users to simulate alarm conditions for testing purposes.

Versions: Two versions are available: one with individual LEDs and another with illuminated, dimmable text fields suitable for ship bridges.

Analog Input Adjustment: Alarms 9 and 10 can be configured for analog mode with a 4-20 mA DC current signal. Switching points are adjustable via spindle trimmers on the lower circuit board, with a table provided for rough pre-adjustment.

Technical Specifications: The device operates on a 24VDC power supply with a tolerance of ±25%, consuming approximately 0.3A. Relay contacts support up to 2A at 48V. It functions within a temperature range of 0-65°C and can handle up to 99% relative humidity. The front protection degree is IP20, or IP54 with a front cap, and the unit weighs approximately 1.5 kg.
