Analog Panel Meter Instruction Manual

INTRODUCTION

The APM 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 opera-

tion.

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 APM rate/totalizer meter has the following: four SPDT relays, 4-20 mA

output, and two 24 VDC power supplies. The APM 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 APM an excellent addition to any system.
