1. INTRODUCTION
Thank you for purchasing the AD-4532B, Digital Indicator.
This manual describes how the AD-4532B works and how to get the most out of it in terms of
performance. Please read this manual completely before using the AD-4532B.
1-1 Features
The AD-4532B has the following features.
High-speed conversion
A 2000 times-per-second high-speed A/D converter is used for inputs from sensors.
A 2000 times-per-second high-speed D/A converter is used for analog outputs.
Calibration without actual load (Digital span mode)
Keying in the sensor’s rated output voltage (mV/V) allows calibration to be performed without
using an actual load.
Various input sources
Upper and lower limit values can be input with front panel keys or by using the Modbus RTU
interface with an external computer.
The front panel keys, contact signals on the rear panel, and the Modbus port can be used for zero
adjustment and peak holding.
Hold function
Sample, peak, bottom and bipolar peak values can be held by using the hold mode.
Comparison function
Comparison results (HI, OK and LO) are output as display data and also as contact signals.
5-level comparison (2D comparator mode) is available using the comparator mode. The LED color
depends on the comparison result in the 2D comparator mode.
Various data output terminals
Analog amplifier output (AAO), D/A voltage output (DAV) and comparator output are provided as
standard with the AD-4532B.
Available options include BCD parallel output, RS-232C serial interface, analog voltage output
(DAV)/analog current output (DAI) and Ethernet interface
3-colored LED display
The 3-colored LED display, that varies with the mode or setting, is used for easier viewing.
