INTRODUCTION

1.1 Description

This device can be purchased as monitor (read process value only) or as
a controller.
• The iSeries Temperature/Process controllers offer unparalleled flexibility in
process measurement. Each unit allows the user to select the input type,
from 10 thermocouple types (J, K, T, E, R, S, B, C, N and J DIN), Pt RTDs
(100, 500 or 1000 , with either 385 or 392 curve), analog voltage or current
input. The voltage/current inputs are fully scalable to virtually all engineering
units, with selectable decimal point, perfect for use with pressure, flow or
other process input.
• The temperature and process control can be achieved by using On/Off or
PID control strategy. Control can be optimized with an Auto Tune feature.
The instrument offers a ramp to set point with timed soak period before
switching off the output.
• The iSeries device features a large, three color programmable display with
capability to change a color every time the Alarm is triggered. The standard
features include three outputs with relay, SSR, dc pulse, and isolated analog
voltage or current output. Options include programmable RS232 or RS485
serial communication and excitation. Analog Output is fully scaleable and
configured as retransmission to follow your display. Universal power supply
accepts 90 to 240 Vac. Low voltage power option accepts 24 Vac or 20 to
36 Vdc.
