What is DAIHATSU MDP-REVD Speed Switch?

The DAIHATSU MDP-REVD is an electronic speed monitoring module designed to detect engine rotational speed and compare it against preset operational parameters.

The unit receives speed signals from engine sensors and continuously evaluates RPM conditions. When abnormal speed conditions occur, it activates alarms or protection outputs to prevent engine damage.

This makes it an important component within marine engine safety and automation systems.

Main Functions

Engine RPM Monitoring

Continuously supervises engine rotational speed.

Overspeed Protection

Detects dangerous overspeed conditions.

Underspeed Detection

Monitors low-speed abnormalities.

Alarm Generation

Why Engine Speed Monitoring is Important

Marine diesel engines operate under varying load conditions.

Without proper speed monitoring:

• Engine overspeed may occur
• Mechanical damage can result
• Generator instability may develop
• Safety systems may fail to respond
• Unexpected shutdowns may occur

The DAIHATSU MDP-REVD Speed Switch helps prevent these situations by continuously monitoring engine RPM.

Working Principle

Step 1

The engine speed sensor generates pulse signals.

Step 2

The MDP-REVD receives the RPM signal.

Step 3

Internal electronics calculate engine speed.

Step 4

The measured RPM is compared with preset values.

Step 5

Normal operation continues when speed remains within limits.

Step 6

Alarm or shutdown outputs activate if abnormal speed conditions occur.
