Current consumption: 5V, 0.12A; 26V, 0.07A.
Standards: UC1, N, CE.
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 20mA,
into digital values, and takes the values,
scaled in industrial units, and transfers,
it to the CPU Unit as the process value E3RA-DN21.
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 savinngs in cost and space compared,
with previous systems E3RA-DN21.
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/LCCUss,
to construct complete process control systems E3RA-DN21.
Parameters can be easily displayed and set in an,
easy-to-understand form without special tools.
