PROFIBUS PA / FOUNDATION™ Fieldbus transmitter

5350B

Linearized temperature measurement with RTD or TC sensor.
Difference, average or redundancy temperature measurement with RTD or TC sensor.
Linear resistance, potentiometer and bipolar mV measurement.

Bus transmitter with both PROFIBUS PA and FOUNDATION Fieldbus communication. A unique switch function ensures automatic shift between the two protocols.
Set-up for PROFIBUS PA can be done via Siemens Simatic^® PDM^®, ABB Melody / Harmony and Metso DNA software and for FOUNDATION Fieldbus via Emerson DeltaV, Yokogawa CS 1000 / CS 3000, ABB Melody / Harmony and Honeywell Experion software.
The simulation mode function can be activated by way of a magnet.
Polarity-independent bus connection.
24 bit A/D converter ensures high resolution.
PROFIBUS PA function blocks:
2 analog.
FOUNDATION Fieldbus function blocks:
2 analog and 1 PID.
FOUNDATION Fieldbus capability:
Basic or LAS.
