Introduction - A&D AD-4408A Instruction Manual

2. Introduction

The AD-4408A is a weighing indicator that amplifies signals from a load cell,
converts it to digital data and displays it as a weight value.
Connection to various field networks is possible by installing the interface module
into the option slot.
• For details on applicable field networks, visit our website.
• Download the instruction manual for each interface from our website. (Memory
map and check modes vary with the interface.)
• The interface module used is the Anybus-CompactCom network interface module,
manufactured by HMS Industrial Networks.
• The interface module is available as an accessory for the AD-4408A. Purchase
the interface module from A&D, or directly from an iterface module supplier.
The accessory panel mount packing will provide the indicator with IP-65 protection.
This indicator has the following performance:
Input sensitivity: ......................... 0.15 μV /d
Display resolution: ..................... 999,999 d max.
Sampling rate:............................ 100 times/second
Input voltage range: ................... -35 mV to +35 mV (-7 mV/V to +7 mV/V)
Digital span mode:
Keying in the load cell output voltage (mV/V) allows calibration to be performed
without an actual load.
NOTE: The unit, d indicates a minimum division.
