Refer to the TC 50 documentation supplied with the product.
There are two other types of connectors available in addition to the removable connectors
supplied. They enable a simplified installation, where applicable.
1 – External dual connector: 07 ST 50
This connector is used to connect sensors or three wire digital actuators to the 40 and 50
series products.
All the terminal blocks of the same level are electrically connected.
2 – External dual connector: 07 ST 51
This connector permits the easy connection of analog sensors to the 40 and 50 series
products.
It includes a first level with 9 interlinked terminals. It may be used to connect the shielding of
the analog cables.
The second level (5 terminals) is used when the 4-wire probes are used. This connector
prevents a short circuit on a channel from disturbing the operation of the other channels.
An example of the cabling of a 4-wire probe to an XM 06 B5 analog unit using a dual connector
can be found in chapter 4.
