Microchron ® II Vital Timer (AC)Features• Simple time delay adjustment• Replaces AC Motor Timers via acommon registration plate• Interruption of power causesthe unit to reset timing interval• Accuracy is + 0.1% of time setting(plus a max. delay of 0.75 sec.)• Timing range from 1.0 second to19 minutes 59.9 secondsMicrochron IIVital Timer Relay (AC)• Time settings in 0.1 secondincrementsThe AC Microchron II Timer, based upon the same proven design as the DC MICROCHRON, provides the ability to replaceboth 25Hz and 60Hz AC motor timers with a solid state unit. Using the same design principles as DC Microchron, the ACMicrochron features a wide voltage range and selectable time range, which eliminates the need to stock separate timers withdifferent time ranges.FeaturesVital Relays• Wide Voltage RangeThe AC Microchron II Timer has a wide inputoperating range of 88VRMS to +135VRMS for the 60Hzversion, 44VRMS to 66VRMS for the 25Hz version.• Simple, 0.1 Second TimeDelay AdjustmentA tactile thumbwheel provides precise time settings ineasy-to-read 0.1 second increments. Time delays maybe set from 1.0 second to 19 minutes and 59.9 seconds.• Lead Seal OptionThe AC Microchron II includes a lead seal over the timesetting thumbwheel to prevent inadvertent delays setting.• Fail-Safe PerformanceThe time delay will never be shorter than the settime interval.• Simple InstallationThe timer may be rack-, wall- or shelf-mounted.It is plug-compatible with Type B2 electromechanicalAC-timer relays.106CALL 800.717.4477 • FAX 585.274.8777
