Temperature and humidity transducer TRS-04a

compactRS-485Modbus

The temperature and humidity transducer is designed for multipoint temperature and humidity measurement systems. In particular it is used for measuring conditions in rooms where food products are manufactured and stored. - Inputs : temp. sensor: semiconductor integrated circuit; measurement range -40°C ÷ +70°C; measurement error ±0,5°C; humidity sensor: 0 ÷ 100% RH, accuracy ±2% RH @25°C Power consumption : during Modbus transmission: up to 60 mA Operating temperature : 0°C ÷ +70°C (non-condensing) Protection class : IP 65 (case), IP 30 (sensor) Power supply : typ. 10V DC (9V DC ÷ 12V DC) Communication interface : RS-485 / Modbus RTU Storage temperature : -40°C ÷ +85°C Case dimensions : 63 x 58 x 35 mm Mounting : to wall, 2 M3 bolts Transmission parameters : 9600 bit/sec Connection cable : 4 conductors (2 supply conductors + 2 data transmission conductors) Number of modules in 1 network: max. 127 Remarks : Do not exceed the temperature range of 0 - 70°C. The module should not be used where water vapour condensation occurs.
