Coin Counting Timers - MC Series Timers
MC Series Coin Counter

The MC series Coin Counting Timers combine a single shot timing mode and coin counting capability with microprocessor technology for reliability and accuracy. Two 4-position binary switches allow users to select the number of coins as well as the time period. The switches can accommodate from 1 to 15 coins and accurately set time periods from .5 to 7.5 minutes with excellent repeatability. The units have an option of an accumulation function, a last coin alarm or an output to a coin counter.

When required, the unit can be supplied with a fixed factory-set coin count or time period. The MC series coin counters come complete with a relay capable of switching loads up to 20 amps,1.5HP. The electronic components are encapsulated in a 2.5" square package for protection from the elements.

Timing Mode

Input voltage is applied continuously. After the correct amount of coins has been counted by the timer, the relay will energize for the selected time period. This unit will automatically reset, after the selected time period expires and is ready for another cycle.
