2. APP ICATION
Transducer DES-215-PT is used to for connection of PT100, PT500, PT1000 sensors, compliant with standard PN-EN 60751+A2, to
1-W RE bus. The transmitter supports the PT100, PT500, PT1000 (B class) sensors, in the range of -200°C...+600°C.
Use of 1-Wire bus allows:
–the cooperation of many sensors connected to the same data lines,
–the deployment of sensors in various locations up to 260m,
–powering the sensors from the bus,
–correct transmission of measurement data secure check sum CRC.
Transducer DES-215-PT can be installed on the wall inside or outside buildings.
3. COOPERATION WITH OTHER 1-WIRE DEVICES
Transducer DES-215-PT cooperates with 1-W RE devices used for creation of monitoring and control systems for environmental
parameters:
– ADA-401WP Measuring Module 1-W RE to MODBUS-RTU,
– DNB-400 Passive 1-W RE Bus Splitter,
