Direct-reading time-scale and compact body MS4S Super Timer
MS4S series Super Timers feature an easy setting and direct-reading system of four time-scale. MS4SM timer is multimode operation type and MS4SA and MS4SC timers are on-delay operation type.
• LED power ON and output indicator The power-source lamp (Green) is lit when power is on and flickers during timer operation. The output lamp (Red) is lit when the timed NO contact is on. • Wide range of AC supply voltage Supply voltages of 100 to 240V AC are commonly available (ordering code: AP type only). • Instantaneous operation function with 0 indication When the timer dial is set at 0, output is given instantaneously, allowing sequence checks to be performed easily. • Time unit indication window and time unit selector By turning the time selector, time units of 0.1 sec., sec., min, and hours. can be selected and made to appear in the indication window. • Improvement of resistance to waveform distortion The resistance to distortion of secondary voltage waveform of the power supply caused by inverters and uninterruptible power supplies (UPS) is improved.
■ Timing range/16 ranges
• Time-scale indication window and time-scale selector By turning a time-scale selector, the timing-scales appear in the indication windows one set a time. Although this is a multimode timer, the optional times such as 56 or 27 minutes can be easily set with the direct-reading time-scale. • Compact timer with instantaneous contact On-delay timers with instantaneous contact, as well as multimode and on-delay timers, are compact. The front to back length of the timers is only 66.5mm. • Operation mode indication window and operation mode selector Four operation modes are provided (MS4SM type only). By turning the operation mode selector, the on-delay, flicker, oneshot, or signal off-delay operation mode can be selected. The present mode is shown in the operation mode indication window with the marks PO, FL, OS or SF.
