® PD6300 is a multipurpose, easy to use pulse rate/totalizer ideal for
flow rate, total, and control applications. It accepts pulse (e.g. ±40 mV to ±8 V),
square wave (0-5 V, 0-12 V, or 0-24 V), open collector, NPN, PNP, TTL or switch
contact signals. Three of the front panel buttons can be custom-programmed for
specific operation.
The basic model includes an isolated 24 VDC transmitter power supply that can
be used to power the input transmitter or other devices. An additional isolated
24 VDC power supply is included with the 4-20 mA output option.
A fully loaded PD6300 pulse rate/totalizer meter has the following: four SPDT relays,
4-20 mA output, and two 24 VDC power supplies. The PD6300 capabilities may be
enhanced by adding the following external expansion modules: four SPST relays
(creating an eight-relay rate/totalizer), two digital I/O modules with four inputs and
four outputs each, and RS-232 or RS-485 communication adapters.
The eight relays can be used for alarm indication or process control applications.
The 4-20 mA isolated output, Modbus RTU serial communications, and digital I/O
options make the PD6300 an excellent addition to any system.
