Detector:Connect a resistance thermometer sensor PT100 as adetectors and it detect temperature.

Transmitter: (1) Detects resistance value which changes
depending on temperature.
(2) The internal CPU makes the temperature data out of
the result of (1) which based on the reference resistancevalue which is specified by JIS-C1604, then chenges thetemperature data to digital signals and transmits thesignals to the Output Sensor.

◆ Ensure the power is switched off during installation or
maintenance operations.
◆ Use a regulated power supply, e.g. switch-model type.
Simpler power supplies, such as a full-wave rectification type,will cause the permissible ripple rating to be exceed and may
cause malfunction.

ABU( - )【Causion】
Please note that the cable length of an output sensor may not longer than 10m.
The CE marking verifies that our products comply with the requirements ofEMC directive. The surge test to an output sensor is not carried out.
When using RTT or RTE with cable length longer than10 m a measure toprotect the sensor from serge current should be taken.

Before using the Remote Sensor, read this manual carefully.
During installation and operation, pay close attention to the safety
aspect.

Mutual interference
In order to prevent mutual interference between parallel-mountedsensors, keep minimum spacing as described below;

Output Sensor: Change the temperature data to analog signal (4...20mA)
and output to external unit and supplies power for
operation of Transmitter at the same time.

◆ Ensure correct connections by reference to the wiring diagram.
◆ To avoid malfunction caused by induction noise, cable should
be kept apart from motor or other power cable.
