422AR with terminals 

  • Six Selectable Ranges: 1 and 10 SEC/MIN/HRS
  • Individual adjustable ON-time and OFF-time
  • Cycle can begin with relay energized or de-energized
  • Relay rated 10A @ 250 VAC Resistive
  • Compact Size (1/16 DIN)
  • DPDT Relay Output
  • Power: 20VAC to 240VAC; 12VDC to 240VDC
  • LED Indicator for Power and Relay energized output

The ATC 422AR Flip-Flop timer from the Automatic Timing and Controls division of Marsh Bellofram is available with Repeat Cycle operations. During Repeat Cycle operation the ATC 422AR cycle 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 ATC  422AR can be configured with either the relay being energized during the first timing period or de-energized during the first timing period.

The ATC 422AR have 6 selectable timing ranges available for both ON-time and OFF-time periods. The ranges are 1 and 10 SEC/MIN/HRS dip switch selectable. Having this flexibility allows for a load to be energized for a brief time over a cycle that lasts up to 10 hours. This is deal for lubrication or other maintenance functins that must occur each shift or day during a plant operation.

The ATC 422AR 1/16 DIN housing is compact, and designed for panel mounting. The timer is mounted in an 8-pin round socket. The front of the ATC 422AR 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 ATC  422AR is universal powered by 20 to 240 VAC or 12 to 240 VDC operation voltage.

The output of the ATC 422AR Flip-Flop timer has a DPDT mechanical relay which is rated for 10 amps @ 250 VAC resistive. The ATC 422AR can be ordered in a terminal option which is only available with 5 amp Relay output. The ATC  422’s have individual LED indicators for ON time and OFF time. These LED’s provide a unique and effective method of cycle progress indication.
