The EXP-EL-CDT.D-M1-120V from Larson Electronics is an Explosion Proof Digital Countdown Timer that is suitable for use in hazardous locations, confined spaces and industrial facilities. This NEMA-rated unit is compatible with 120 V AC, 50/60 Hz. Magnetic switches enable operators to set the amount of hours without opening the enclosure after installation. The EXP-EL-CDT.D-M1-120V is designed for Class I, II and III rated combustible sites. Equipped with an LCD display, the device contains magnetic switches that allow operators to change the hour settings after installation without opening the enclosure. This feature works through the glass of the clock, enabling operators to change the time settings quickly and safely. Time adjustments with the magnetic switches can be completed in the field (hazardous area). This unit also features buttons for start, stop, and pause which are also controlled by magnetic switches. The timer is protected by a copper-free aluminum housing for durability. Neoprene 0-rings are provided with the enclosure to ensure water resistance in NEMA 4/IP66 conditions.

This digital countdown timer is equipped with a set of aux contacts for controlling external equipment such as indicator lights or for sending signals to controllers. These contacts are normally open and will close to complete the circuit once the timer starts. Voltage: This digital countdown timer operates on 120 V AC, 50/60 Hz. The explosion proof timer comes with offset feed-thru conduit openings (3/4" NPT). An internal ground screw is conveniently located away from the mounting components. The enclosure is finished with silver powder epoxy paint (electrostatically applied). The ground screws are made out of zinc plated steel with green dye, while the allen head cover screw is constructed of cadmium plated steel.
