Amplifier Busbox Profibus nmMn Special Features • Amplifier with Profibus interface • User friendly commissioning via GSD file • Transmission rate up to 12 Mbit/s • 16 bit resolution Busbox-P2 Single channel amplifier for one or two strain gauge sensors in an aluminum enclosure suitable for field mounting. Protection class IP67 Weight 175 g Busbox-PS2 Single channel amplifier with one strain gauge sensors connection in an aluminum enclosure suitable for DIN rail mounting. Amplification of 2 strain gauge sensors possible. Protection class IP20 Weight 175 g Option - Option F (Ex-protection): Use with safety barriers Busbox-PEZ Dual channel amplifier for two strain gauge sensors. Consisting of two Busboxes-PS2 with wiring to the terminal block in high-quality stainless steel enclosures suitable for aggressive surroundings, e. g. in rolling mills. Each web tension sensor at each roll end is assigned to its individual amplifier, which is connected to the Profibus with its own individual address for transmitting the measured force value. Protection class IP67 The Busboxes are used whenever full bridge strain gauge sensors are to be connected to the Profibus DP. The primary field of application is web tension measurement. It is possible to connect either each sensor separately to one Busbox and transmit the measurement value of each sensor onto the Bus or connect two sensors to one Busbox to get the average value. The Profibus amplifier consists of an analog and a digital module. It can power one or two sensors and process the measuring signals. The measurement values are converted into digital signals, averaged and transmitted to the interfaces module every 3 milliseconds. The interface module converts the signal to the appropriate data format for transmission to the bus.
