M u l t i - R a Automatic Timing & Controls automatictiming.com 800.727.5646 422A Series The 4 42 22 2A A F FL LIIP P- -F FL LO OP P is available with Repeat Cycle operation. During Repeat Cycle operation the 422A cycles ON and OFF repeatedly, allowing periodic cycling of a load. Two knobs are available to individually adjust the ON- time and the OFF-time. The 422A can be ordered with either the relay being energized during the first timing period or de-energized during the first timing period. The 422A FLIP-FLOP is also available with Single Cycle operation. With Single Cycle operation, the 422A will cycle ON and OFF one time. This is commonly referred to as “one-shot” operation. The 422A can be ordered with the relay being energized during the first timing period or de-energized during the first timing period. There are six selectable timing ranges available for the ON-time period and 6 selectable ranges for the OFF-time period. These ranges can be ordered as either 1 and 10 SEC/MIN/HRS or 5 and 50 SEC/MIN/HRS. Having these ranges individually selectable for ON-time and OFF-time allows for a load to be energized for a brief time over a cycle that can last up to 50 hours. This is ideal for lubrication or other maintenance functions that must occur each shift or day during a plant operation. The 422A’s 1/8 DIN housing is compact, and designed for panel mounting. The timer is mounted in an 8-pin round (octal) socket. The front of the 422A features 2 knobs. One knob is used to set the On-time and the other knob is used to set the Off-time for the timer’s cycle. The timing range for the On-time and Off-time can be individually set. The range select switches are located on the side of the hous- • Six Selectable Ranges: ing, so that when panel mounted, these switches are not accessi- 1 and 10 SEC/MIN/HRS ble to the operator.
