Ambient air temperature transducer TRS-02a

Pt100wall-mountcompact

The temperature transducer is designed for multipoint measurement of temperature by means of a standard Pt100 sensor. In particular it is designed for use with bayonet sensors to be used, for example, in smoke-houses. It may be used with any Pt100 sensors. This module features very good compensation of effect of connection cable resistance on the result of temperature measurement. Non-linear characteristics of the sensor is digitally linearized. Inputs : temp. sensor: Pt 100; measurement range -50°C ÷ +550°C; measurement error ±0,2% Power consumption : 12 mA; during Modbus transmission: do 65 mA Operating temperature : -40°C ÷ +85°C Protection class : IP 65 Power supply : typ. 10V DC (9V DC ÷ 12V DC) Communication interface : RS-485 / Modbus RTU Storage temperature : -40°C ÷ +85°C Case dimensions: 80 x 82 x 55 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 : Acceptable connection cord resistance: up to 20 W in each cord!
