9221, Universal Sensor Input Profibus Module

The universal sensor Profibus module is well-suited for measurement of mechanical values such as e.g. force, torque, pressure, acceleration, displacement and angle. Strain gauge, potentiometric and standard signals may be captured and processed without problems. A powerful 16 bit A/D converter ensures a precise and fast processing of analog sensor signals.

The module itself features a stable and precise sensor excitation voltage. The calibration and configuration data are memorized on an EEPROM, protected against zero voltage.

The user friendly configuration software makes a simple conditioning of input signals and the setup of parameters on the module with regards to the PLC and Profibus parameters possible. The version DPV1 enables the parameterization and backup function via Profibus. Functions such as the arithmetical calculation of mean values, input signal filtering, zero adjustment, MIN/MAX memory and limits setpoint values can be realized with a speed of up to 12 MBaud via Profibus.

Two potential-free and freely configurable digital inputs are available for the external PLC control (e.g. erase MIN/MAX memory, tare function). Two digital outputs can be defined as local limits switches for alerting functions.

The bus-sided control of the sensor lines on fractures or short-circuits and the galvanic separation between the Profibus-ASIC and the Profibus connector belong to the standard features.

The visualization of operating conditions such as bus connection, sensor-sided errors or active state of module are realized by three LEDs. The DIN standard mounting rail enables an easy installation into the control cabinet.
