1 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, allowing 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.
The relay may be configured to either energize or de-energize when the pre-set number of pulses have been counted.
Pulses can be acknowledged when the pulse pins are either shorted OR released.
A prescaler 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, eliminating the need to generate reset pulses manually.
By using this timer function, the output pulse length can be varied from 0.1 to 99.9 sec.
When monitoring frequency the hysteresis may be set from 1 to 50% of the set-point. A latch facility and 10 second start-up timer is also incorporated.

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
