Apresentação
The Universal Remote Ethernet WUC-712 is
designed to promote versatility and robustness in
industrial plants.
With is processing core based in the ARM®
technology, the WUC-712 offers speed and
accessibility to field variables through the Modbus
TCP protocol over Ethernet and also through the
Modbus RTU protocol over the RS-485 physical
interface, thus enabling the acquisition of 16 inputs
from several kind of signals such as
thermocouples, RTD resistive sensors, current,
tension, frequency and logical levels.
The available inputs and product features are
described below:
Thermocouples type J, K, T, R, S, E, N, B (ITS-90) with cold junction compensation
RTD type Pt100 (two or three wires)
Current 0-20 mA and 4-20 mA
Voltage 0 –75 mV, 0 –5 V or 0 –10 V
Logic level maximum amplitude 12 Vdc
Frequency up to 10 kHz with 4 simultaneous channels with 0.3 V to 50 V sensibility
Two digital inputs isolated up to 30 Vdc for alarm acknowledgment
Two alarm levels per channel, configurable (high, low, or differential) with hysteresis and delay of 1 to
10 seconds
Two relay outputs for alarm status
Fully detachable (plug-in type) connection to the terminal block
Integrated Ethernet switch
The WUC-712 is configured by the universal Wirebus configuration tool WireConfig.

Typical Applications
The Universal Remote Ethernet WUC-712 is designed to several types of industrial
applications, enabling the concentration of distributed field data. The WUC-712 applications
demonstrate high optimization in remote field data acquisition, which were previously delegated to
controllers, increasing the process scalability and decreasing costs.
The 16 inputs of the WUC-712 acquire reliable data for SCADA systems.
