Model PD6200 Analog Input Rate/Totalizer 

Instruction Manual 

7

 

INTRODUCTION 

The PD6200 is a multipurpose, easy to use rate/totalizer ideal for flow rate, total, 
and control applications. It accepts current and voltage signals (e.g. 4-20 mA, 
0-10 V). 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 PD6200 rate/totalizer meter has the following: four SPDT relays, 
4-20 mA output, and two 24 VDC power supplies. The PD6200 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, 
such as pump alternation control. The 4-20 mA isolated output, serial communica-
tions, and digital I/O options make the PD6200 an excellent addition to any system.
