4970-2

The 4970-2 is a highly flexible Countdown Interval Timer with screw terminals, digital display of timing controlling a set of high current output contacts. The two arrow buttons on front panel are used to set time, the up button increases time and the down decreases it. The longer a button is held down the faster the rate at which the time value will change, the time value rolls around at both ends of the time range. The start/stop button performs multiple functions. Pressing the start/stop button while the timer is idle will energize the output power relay contacts and the controller begins counting down the time on the display, once the display reaches 0 the contacts de-energize and the unit alarms for 5seconds and then returns to the original cycle time. It always remembers the last interval time programmed and when first powered up resets to that time. The LED above the 4-digit display flashes during the timing cycle to indicate timing and is on continuously when the cycle ended.
