DP-7951
This versatile time relay has 8 modes of operation, 9 timing ranges and a
large easy to read LCD display with numerical information. The display carries a
wide range of internationally understood annunciators to indicate all the modes,
direction of timing and the status of the output at all times.
The timing input can be level triggered, edge triggered or edge retriggerable.
The essence of RE-triggering is that subsequent pulses on the timing input can start
a new timing cycle. Time is on the Main Display and the Set Time on the Subsidiary
Display.
8 timing modes: on deLay (ON DLY), offdelay (OFF DLY), one shot (OS) and single
shot (SS). repeat cycle (RC) modes: delay, cycle, symmetrical delay and symmetrical.
