Active and Passive Temperature Transmitters for Solar Panels
HD48… active and HD49.. passive temperature transmitters complete with contact temperature probe for solar panels with 5 or 10m cable, 1/3DIN thin-film Pt100 sensor.
- Thanks to the RS485 output, several instruments can be connected to form a network
- The instruments are connected in a sequence through a shielded cable with twisted pair for signals and a third wire for the mass
HD48…is available with active 4…20mA or 0…10V analogue output, or with the only RS485 MODBUS-RTU output.
HD49… is available with passive 4..20mA output. Versions with analogue output provide a signal suitable to be transmitted to a remote display, a recorder or a PLC. The versions with RS485 output are suitable for connection to a PC or a PLC.
Probe operating temperature: 0…+80°C. Also available with LCD (option L).
Working temperature of the electronics: -5°C…+60°C.
Power supply: 16…40Vdc or 24Vac for models HD48…, 12…40Vdc for models HD49…
Upon request, HD48… can be provided for 90…240Vac power supply, but only in 80x120mm housing, height 56mm, without display.
