P44-CNT2

dual colour LED display

2 RELAY

These devices incorporate 2 relays. If relay 1 is configured
for COUNTING, relay 2 may be configured as a COUNTER,
RPM, Freq, PPh monitor. If relay 1 is configured for a mode
other than COUNTER, then both relay 1 and 2 are automatically
configured foir the same function.ie. The device cannot
simultaneously montor RPM and Freq. or RPM and PPh.

Relay 2 may be programmed as a COUNTER (of pulses
received) OR it can increment whenever COUNTER 1 has
reached it’s setpoint. (counter of counter 1 setpoints reached).
Dual relay devices may also be configured as a COUNTER on
relay 1, while simultaneously monitoring the rate of the pulses
received on relay 2. (RPM, Freq or PPh)
The latch / reset pin functionality may be enabled and displayed
independantly for each relay.
The relays may be configured to energise or de-energise when
the setpoint(s) are reached.

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

Pulse source type mechanical switch or NPN proximity

All parameters are saved to non-volatile eeprom memory, thus eliminating the need to re-program after a power failure

incorporates a crystal oscillator to maintain accurate timing
