0 RELAY

This device may be configured for counting or frequency monitoring functions.
Using the "save" function, the state of the counter is saved to non-volatile memory during power failures. This allows the device to continue from where it left off before the power was removed.
A 10V - 24V DC supply (± 30mA) is included for use with NPN proximity switches.
Pulses can be acknowledged when the pulse pins are either shorted OR released.
A pre-scaler of up to 200 is included. (the device reads the "pre scale" amount of pulses before updating the counter value).
The post-scaler multiplies the pulses received by up to 200.
Pulses may be displayed as lapsed (up-counting), remaining (down counting) or frequency (even if configured for counting).
Using the reset timer the device can automatically be reset between 0.1 and 99.9 seconds after the pre-set number of pulses have been counted. This eliminates the need to generate reset pulses manually.

ADDITIONAL FEATURES INCLUDE:

  • relay operates (or gives a pulse) upon reaching the pre-set number of pulses
  • reversed relay action to open contacts when count is reached
  • interfaces with NPN proxy, photo switches (10-30V 30mA power supply included)
  • select leading or trailing edge of pulse (when pulse open or closes)
  • reset via external pulse or BUILT-IN timer (0.1 - 99.9sec after count is reached)
  • pre-scaler divedes pulses automatically (one item = multiple pulses)
  • post scaler multiplies pulses automatically (multiple items = 1 pulse)
  • display lapsed or remaining pulses
  • selectable save status (after power failure, device can either continue from where it left or reset)
  • configurable to monitor frequency of pulses
  • keypad lock
