  • Page 7: Introduction

    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.
