WIKA operating instructions temperature transmitter, model T19
4.2 Mounting for rail mounting version
The transmitters for rail mounting (model T19.30) are designed for
mounting on a standard rail or for wall mounting.
■ Rail mounting
The transmitter is affixed without the use of auxiliary parts by sliding
onto a 35 mm top hat rail (DIN EN 50022-35).
Demounting is done by freeing the snap parts.
■ Wall mounting
Lever the snap parts outwards with a screwdriver until they lock into
place. Mount case to the wall by means of two screws.
5. Electrical connections
In the case of the transmitters described here there is an
internal galvanic connection between the sensor input and
analogue output.
No external conducting is to be made (for example, by
earthing) between the connected temperature sensor and
analogue output!
We recommend the use of crimped connector sleeves in the
case of flexible leads.
For model T19.30 the connection cable of a temperature
probe must be shielded and grounded.
To connect a Pt100 sensor in a 2-wire connecting circuit:
Set a jumper between the input terminals 2 and 3 in accordance with
section 5.1.!
