MUXM
Concentrator for TM temperature probes and TU humidity probes (pending). Up to max. 32 TU+TM probes can be connected to
each MUXM. With 32 connected TM probes, and each probe with 50 temperature measuring points (highest possible option), the
total is 1600 controllable points. The electrical connection between the probe and the MUXM is made with a screened cable, while
the connection between the MUXM and the AGRITHERM-50 control unit is made with screened bipolar cable for data
communication via MODBUS RTU. The MUXM and the connected probes conguration is made via the VL701 removable module
and operations are displayed by the O-LED display. Up to 63 “MUXM” can be connected by MODBUS serial network.

5.1 INSTALLATION PRECAUTIONS
- Installation shall only be performed by quali ed personnel and in accordance with local governing regulations.
- Make sure that the working temperature is between -20 and +70°C
- Install the concentrator in a its physical characteristics and housing construction materials compatible environment.
- The concentrator must be used safety warnings observance.
- Improper transmitter use would cause serious damage to people, to the product and connected equipment.
- Do not open the housing in the presence of potentially explosive dust
5-ELECTRICAL CONNECTIONS
MUXM - electrical connections
5.2 ADVICE FOR EXTERNAL MOUNTING
- for electrical connections, use a cable with a 6÷12mm outer diameter and fully tighten the M20x1.5 cable gland
- correctly close the cover, and fully tighten the screws.
- For connections between MUXM and TM use probes FUTP2PR AWG624/1 CAT. 5E cable
- position the cable so that it forms a downward curve at the cable glands output; in this way the condensation and/or rain water
will tend to drip from the bottom curve (as shown below).
