Honeywell 2MLF-AV8A User Manual

R200 Analog Input Module 2MLF-AV8A, AC8A User's Guide 15
September 2010 Honeywell
1. Introduction
1.1 Overview
This user’s guide describes two analog input modules.
• 2MLF-AV8A type voltage to digital conversion module
• 2MLF-AC8A type current to digital conversion module.
Both A/D conversion modules are used for converting analog signals (voltage or current
input) from PLC’s external device to signed 16-bit binary data of digital value. They are
used with MasterLogic-200 CPU module, ML200-IEC (2MLI-CPUU), and ML200R
(2MLR-CPUH).
1.2 Features
1. Module selection: You can choose the module depending on input signal type.
a) 2MLF-AV8A: 8 channels, voltage input
b) 2MLF-AC8A: 8 channels, current input
2. High speed A/D conversion @ 250 µs/channel.
3. High conversion accuracy of ±0.2% (ambient temperature of 25 ± 5
o
4. High resolution (16-bit) of digital value, that is, 1/16000.
C).
5. Simplified module setup/monitoring through GUI:
Setting up an A/D conversion module’s operation parameters (that is, range, filter,
and so on.) was traditionally a cumbersome process using repetitive sequences of
ladder programs. This is now achieved using a user-friendly graphical user interface
(GUI) in SoftMaster I/O Parameters. In addition, the A/D conversion value can also
be easily monitored using the Special Module Monitoring function.
6. Multiple digital output data formats: Fours formats are available, as specified
below:
a) Unsigned value: 0 ~ + 16000
b) Signed value: - 8000 ~ + 8000
c) Precise value: Refer to Performance specifications.
d) Percentile value: 0 ~ + 10000
