The MA Series is single level preset counter. This 4 or 6 digits counter counts down from a preset value and a microswitch is activated once count display reaches zero. Preset value can easily be set from the front panel digits and it is equipped with a push button reset or a remote electric reset. The MA Series is actuated by a DC24V, AC100V or AC200V input voltage and it is equipped with an internal circuit that protects the unit from voltage surges. Digit sizes are 3.8 x 2.6mm for the 4-digits and 3.4 x 2.4 mm for the 6-digits. It is a 60 x 60mm panel mounted counter with panel cut-out size of 54 x 54mm which can be secured by a clip/bail. The unit comes with a clear plastic front panel cover to protect it from dust.
