2 Analog Inputs for Pt and Ni Sensors
Rated voltage from the supply terminal 24 VDC Nominal current from field supply ð 30 mA Nominal current from module bus ð 45 mA Power dissipation, typical ð 1 W Inputs Input type Pt100, Pt200, Pt500, Pt1000, Ni100, Ni1000 Electrical isolation electronics for the field level Output connectivity Screw, tension spring Maximum limiting frequency analog 2 Hz Linearity ð 0.1 % Basic fault limit at 23 °C < 0.2 % Repeatability 0.05 % Temperature coefficient < 300 ppm/°C of full scale Resolution 16 Bit Measured-value display 16 bit signed integer 12 bit full range left-justified Cycle time ð 200 ms Measuring current < 1 mA Number of diagnostics bytes 2 Number of parameter bytes 4 ■ Fieldbus and connection technology inde- pendent ■ Protection class IP20 ■ LEDs indicate status and diagnostic ■ Electronics galvanically separated from the field level via optocouplers ■ 2 analog inputs for Pt100, Pt500 and Pt1000 as well as for Ni100 and Ni1000 Functional principle BL20 electronic modules are plugged into the purely passive base modules which are used for connection of field devices. Maintenance is significantly facilitated due to separation of the connection level from the module electronics. Furthermore flexibility is enhanced because the base modules provide a choice of tension spring or screw connection technology. The electronic modules are completely inde- pendent of the type of higher level field bus through the use of gateways.
