1.0 INTRODUCTION

The ANAFAZE 8 PID is a full-featured, industrial-quality, eight- loop, three-mode

controller offering unique shared processing technology in local or distributed systems.

Through shared processing, the operational functions are divided: the ANAFAZE 8 PID

microprocessor intelligence controls the eight loops while a computer or programmable

controller enters control settings and performs other operations as needed.

Up to eight loops can be controlled by each ANAFAZE 8 PID, with separate selection of

setpoints, alarm points and control constants. A group of optically isolated measurement

circuits accept direct connection of sensors -- including thermocouples, RTD's, infrared

non-contact, milliamp, and voltage -- reducing the need for costly isolators or

transmitters. Sensor and control cable costs are reduced by installing the controller near

the process and using serial communication to the host computer. Plug-in RS-232, RS-

422, or 20ma current loop interfaces are available at selectable baud rates. Control output

for each loop is a separate plug-in board with a choice of time proportioning voltage,

on/off output, or analog voltage or current. With the alarm expander option two alarms

can be set for each loop with digital outputs on alarm for annunciation or emergency

shutdown. Indicator LEDs show the status of each loop, the communication interface,

and the AC power.

For simple applications any computer with a serial interface may be used to set the input

types, control constants, control setpoints, and alarm levels for each loop. Once set, the

ANAFAZE 8 PID functions as a stand-alone controller, with alarm checking on each

loop, and the computer need only periodically poll the controller to generate operator

displays and to verify correct operation.

ANAFAZE offers ANASOFT which is a menu driven software applications package for

IBM PC and compatible computers. Please contact ANAFAZE for additional

information.

Up to 32 local or remote ANAFAZE 8 PID controllers can be connected on a single

communication line, totaling 256 loops, and multiple lines can be used for very large

systems. Since the ANAFAZE 8 PID fully controls each loop, supervision requirements

are simplified, thus allowing the use of inexpensive programmable controllers or

personal computers.
