Temperature indicator TRS-11a

4-digitwith LED displayintegrated

The TRS-11a ambient temperature transducer with a display is designed for multipoint temperature measurement within the range of -40°C up to +85°C. It is particularly designed to measure temperature in rooms where food products are manufactured and stored. A display located on the front panel enables the reading of current temperature and autonomous operation of the module (without a computer system). It is equipped with Modbus RTU communication bus. Inputs: temp. sensor : semiconductor integrated circuit; measurement range -40°C ÷ +85°C; measurement error within th range -10°C ÷ +50°C: ±0,5°C Power consumption : up to 30 mA; during Modbus transmission: up to 80 mA Case material : polycarbonate Operating temperature : -40°C ÷ +85°C Protection class : IP 65 (case), IP 40 (sensor) Display : 4 digits 9 mm high, increased brightness Power supply : typ. 10V DC (9V DC ÷ 12V DC) Communication interface : RS-485 / Modbus RTU Storage temperature : -40°C ÷ +85°C Case dimensions : 64 x 58 x 35 mm Mounting : to wall, 2 M3 bolts Transmission parameters : 9600 bit/sec Number of modules in 1 network : max. 127 Connection cable : 4 conductors (2 supply conductors + 2 data transmission conductors)
