8.3.2Junction Box JB 36/42

JB36 and JB42 are used for intrinsically safe connection of up to 14 temperature sensors to a Data Acquisition Unit (DAU). 12 sensors for JB 36 if 3-wire connection is used.

JB 36 and JB42 have three openings for M25 glands, suitable for 9-16 mm cable diameter.

Temperature sensors are connected to the JB 36/42 Junction Box and the DAU via cable as illustrated in Fig. 8-7.

If the DAU is situated on the tank top, temperature sensors can be connected directly to the DAU.
