Provides the functionality of isolators, power supplies, signal converters, and other devices.

• The Analog Input Unit converts analog input signals such as 1 to 5 V or 4 to 20 mA into digital values, and takes the values scaled in industrial units, and transfers it to the CPU Unit as the process value. Because of this, no ladder program is required at the CPU Unit for scaling.
• The Analog Output Unit converts analog output set values from the CPU Unit to analog output signals such as 4 to 20 mA or 1 to 5 V, and outputs them.
• The built-in functions, such as measurement value alarms, rate-of-change calculations, and square roots, have enabled major savings in cost and space compared with previous systems.
• High-resolution Models and 8-point Input Models are also available. By combining the Units, logging/monitoring systems can be constructed, or the Units can be used together with LCBs/LCUs to construct complete process control systems.
• Parameters can be easily displayed and set in an easy-to-understand form without special tools.
