MURPHY EGS21 VM-24-B is an electromechanical relay instrument. It is suitable for 24V DC systems with a range of 16 - 36V.
The output type is a Hall-effect switch that outputs ground signals and uses incremental triggering, making it particularly suitable for voltmeters. The instrument features overvoltage protection, capable of withstanding up to 200% of the nominal voltage for 5 minutes, and also has reverse polarity protection.
The housing is made of polyester (PBT), impact-resistant and waterproof; the bezel is SAE-type low-treated stainless steel (Option B). With a wide operating temperature range from -40°C to +85°C, it operates stably in various environments and is widely used in scenarios requiring voltage monitoring and control.
