Continuous repeat cycle timing in a compact 1/8 DIN case... fast, easy analog dial setpoint adjustment

The DA100 is a solid state ON/OFF repeat cycle timer housed in a 1/8 DIN, molded NORYL® case. The timer uses CMOS integrated circuits for the timing function. Sixteen time ranges are available in any combination of ON and OFF periods. Two knobs reference to a calibrated scale provide the individual time settings. Two front mounted pilot lights indicate timing status.

Operation

N/A The timing base for each of the two timing states (ON time and OFF time) is generated by an internal oscillator set by a precision capacitor and a dial adjustable potentiometer. This allows accurate control over the long time ranges available with the DA1

Features

N/A

  • All connections made through standard square base relay socket
  • Available accessories for conversion into panel mount including a version with plug-in capability
  • Standard unit times its OFF period first and provides an isolated double pole - double throw relay contact output
  • Available options include ON-Time First timing and One-Cycle timing (previously required two time delay relays)
