Raychem Elexant 650c Modbus Control Unit
Raychem Part Number: 1244-022835
The nVent RAYCHEM Elexant 650c-Modbus controller is designed for operation with nVent RAYCHEM ramp, roof and gutter heating cables.
The Modbus connectivity allows for remote monitoring, configuration, and ease of integration in a Building Management System (BMS).
- Intuitive set-up and programming of the unit with a 4.3” colour touch screen
- Moisture and temperature control of roof & gutter de-icing and surface snow melting systems
- Controls 2 independent heating areas
- Temperature with moisture sensing for enhanced energy savings
- Alarm relay with change over contact to signal power, sensor or communication problems (Modbus)
- Ambient temperature monitoring with high and low temperature alarm
- Offsite configurable—can be set up prior to final installation
- DIN rail panel mountable
- The Elexant 650c-Modbus is equipped with a RS485 port for Modbus communication to a BMS system which can be used for configuration, monitoring and alarm purposes
- Ice rain feature—preheating the surface to prevent the issue of freezing rain (for surface snow melting application only)

E650C-G
Raychem Part Number: 1244-022794
Ground sensor for combined measurement of temperature and moisture values in outdoor areas with foot or vehicle traffic. Robust version made of brass, fully encapsulated. Very low installation height, so particularly well suited to staircases, terraces, etc.
E650C-R
Raychem Part Number: 1244-022795
Rod-shaped sensor E650C-R for combined measurement of temperature and moisture values in gutters and neighbouring areas, such as flat roofs and downpipes to be used with Elexant 650c-Modbus. Robust version made of brass, fully encapsulated. Extremely compact design with axial cable outlet and threaded bolt for fixing in position. Optional mounting plate for sensor E650C-R can be used with sensor height adjustment above the mounting surface. The mounting plate can be matched to the mounting location by bending and then attached by gluing or soldering. Two material versions are available for suitable material combinations in gutter and flat roof applications.
