General description
5.2.1. Construction
The threshold detector / temperature transmitter is made of
an electronic module and a measuring element. The electronic
module can be adjusted by 180°.
•
The electrical connection of the 8400 threshold detector is
made via an M12, 5-pin fixed male adjustable connector and,
depending on the version, an EN 175301-803 fixed connector.
•
The electrical connection of the 8400 transmitter is made via
an EN 175301-803 fixed connector and an M12, 8-pin fixed
male connector.
The 8400 requires a 12...30 V DC power supply.
•
Depending on the version, a threshold detector has 1 NPN or
PNP transistor output or 1 relay output.
•
A transmitter has 1 4...20 mA current input, 1 4...20 mA current
output and 1 relay output.
5.2.2. Measuring element
Threshold detectors / temperature transmitters are fitted with a
Pt100 sensor 29.5 mm long.
The Extended versions are fitted with a Pt100 sensor 100 or
200 mm long.
