  Description  
 

PSoC 1 based industrial timer provides cost effective, programmable solution to meet the market requirements. The solution is available in two flavors.

  1. Timers with display (based on CY8C27x43 family)
  2. Timers without display i.e. blind timers (based on CY8C24x23A, CY8C21x23 families)

 

In timers with display, user keys are available to set parameters like time, mode, pass word, etc. The control inputs (Level / Pulse) start and reset the timing operations. The integrated comparator with internal voltage reference in PSoC 1 is used to detect the power down condition to store the parameters in the emulated EEPROM (Flash memory).

In blind timers, potentiometers and DIP switches are used to set the ON / OFF time, time range, unit of time and mode. The on-chip ADC is used to interface with the potentiometers. Blind timers start timing operation immediately after it is powered ON. There is no control input logic in blind timers.

The relay outputs are turned ON (or) OFF based on the timing logic. The LEDs indicate the relay status and power on status.
