DIN Hour Meters

General Details

DIN Hour Meters







DIN Hour Meters in the M240 Series are durable Elapsed time meters (ETM) monitoring “ON/RUN” time of plant and equipment, allowing the user to effectively control production efficiency, cost estimation and service period monitoring for preventative maintenance.

Time is measured in increments of 0.01 hours up to 99999.99 hours after which the meter automatically resets to zero. Meters are non-resettable before this time to prevent accidental resetting. Units available in either 50 Hz or 60 Hz input.

DIN Hour Meters are available in 3 standard case sizes, 48 mm or 72 mm, or 96 mm.

Typical applications include building management, control panels, distribution systems, energy management, generator sets, motor control, process control, switchgear, and utility power monitoring.

Advantages of electromechanical counters are easy installation, are non resettable to avoid tampering. Models have only two terminals for connection and easy set up. There are no configuration settings or setup menus to complicate the installation. Electromechanical units do not require external power.
