Microprocessor-controlled temperature transmitter
■HD9008.T7AC outputs DC4–20mA instrumentation signals, while HD9008.T7S outputs measured temperature values via RS485 Modbus-RTU. ■Despite its compact cylindrical size (φ26×225mm), it incorporates an amplifier and converter. ■HD9008.T7AC allows for scaling of the temperature range against the output. ■HD9008.03 directly outputs the resistance value of a platinum resistance thermometer Pt100. ■For outdoor use, the transmitter should be inserted into a protection hood HD9007A-1 (12 layers) or HD9007A-2 (16 layers) to protect it from sunlight and rain. ■For indoor installation, probe holders HD9008.21.1 (wall distance 250mm) and HD9008.21.2 (wall distance 125mm) are available. ■Protection rating: IP65. ▼Temperature scaling is possible for 4–20mA output (HD9008.T7AC). ▼General-purpose Modbus-RTU output in the PV industry (HD9008.T7S). ▼3-wire Pt100 (Class A) direct output (HD9008.03). ▼Options for outdoor protection hood and indoor holder.
