1.1 About this manual This equipment manual contains important information on the operation, installation and configuration of the Sensor Profibus Module type 9221, IP20 and IP65 versions. Note that the Sensor Profibus module type 9221 must be used in accordance with the instructions, technical data and conditions of use listed in this manual. If handled improperly or used incorrectly, one cannot rule out the possibility of faults, incorrect measurements, effects on or from other equipment and installations or potential risks to life and property. Please note the specific requirements that must...

Equipment function The Sensor Profibus Module type 9221 is intended for the acquisition and processing of sensor signals and digital status information and for producing digital signals for the fieldbus level (Profibus). The Sensor Profibus Module is a user-configurable, single-channel module operated via an RS232 interface (configuration only) or RS485 interface (Profibus-DPV1). The universal Sensor Profibus Module is ideally suited to measuring mechanical variables such as force, torque, pressure, acceleration, displacement and angle. Acquisition and processing of strain-gage, potentiometric...

The Sensor Profibus Module type 9221 has been specifically developed for highspeed control functions and real-time operations, and therefore covers a huge range of applications. The instrument has been designed to integrate the maximum possible range of analog sensor output signals into complex, networked and distributed automation structures. Thanks to its secure and reliable transmission protocol, its high transmission rate and its simple design, the module is perfectly qualified for use in both industrial automation engineering and test-bench technology. Exploiting the instrument's quick response...

Operating instructions for the IP20 version Installation / Fixing The Sensor Profibus Module type 9221 has a snap-fit design for mounting on a standard 35 mm DIN (top-hat) rail to DIN EN 50022. The unit is fixed to the DIN rail via a clip on its rear side. First place the clip on the DIN rail from above and then press the module down onto the DIN rail until the lower edge of the clip snaps onto the DIN rail. For optimum measurement quality the DIN rail must be grounded. To remove the module, once again push down on the module from above while tilting the lower edge of the clip forwards to release...

All terminal blocks have a plug-in design, so they can be removed from the module for convenient cable connection. No more than two wires should be connected to one terminal. Ferrules are recommended for connecting stranded wires. Shielded cables must be used for the voltage-supply lines and signal conductors to avoid interference on sensor signals or in the module.

The Sensor Profibus Module type 9221 has four mounting holes for fixing the module in place. The module must only be installed by a qualified person. The Sensor Profibus Module type 9221 has IP65 degree of protection. The module is therefore protected against ingress of dust and water jets. The permitted ambient temperature range for the Sensor Profibus Module type 9221 during operation is 0 °C to +60 °C. The unit can be stored at temperatures between -30 °C and +85 °C. 5.4 Front panel / terminal assignments Front panel The following diagram shows the plan view of the Sensor Profibus Module with...

Terminal assignments Cables are connected via PG cable glands and screw terminals on the module. All terminal blocks have a plug-in design, so they can be removed from the module for convenient cable connection. No more than 2 wires should be connected to one terminal. Ferrules are recommended for connecting stranded wires. Shielded cables must be used for the voltage-supply lines and signal conductors to avoid interference on sensor signals or in the module. 4: Signal input 3: Signal input + 2: Sensor + 1: Excitation + 3: Ground 24 V 2: Protective ground 7 (10): Monitor output ground 6 (9):...

Block diagram and internal signal processing Voltage supply Profibus Asic Monitor Output The A/D converter amplifies and converts the signals according to the design and type of the connected sensor. The A/D converter digitizes all incoming signals with a resolution of 16 bits. The analog multiplexer and A/D converter are controlled by the microprocessor. The A/D converter contains an amplifier with various amplifier stages. The gain and the corresponding accuracy and resolution of the measured value depends on the measuring range selected. In addition, there is an option for arithmetic averaging...

Before applying the supply voltage to the sensor module, make a final check that the unit is installed correctly and set to the correct voltage. It is essential to check that the unit has been grounded in accordance with regulations and that the supply voltage for all the Sensor modules does not exceed the specified + 36 VDC. 6.4 Terminal assignments 6.5 Supply voltage The Sensor Profibus Module can be supplied with 20 - 36 VDC (d.c. supply) or with 14 - 26VAC (a.c. supply). The instrument has its own internal protection to safeguard the supply input against overvoltage, overcurrent and polarity...
