Modules

CCB 15 V module	The CCB 15 is required for the HERO™ to communicate with a control PC. It features an Ethernet interface, through which a TCP/IP connection is established with the control computer. Data exchange and the parametrization of the HERO™ are achieved using a protocol based on (but not compatible with) IEEE 488.2.
GEN 15 module	The GEN 15 is responsible for signal generation and consists of a DSP 15 base board with up to two expansion modules. The optional second expansion module allows a second independent signal generator to be implemented. The DSP 15 base board acts as an FPGA-based, flexibly configurable signal processor for real-time signal filtering and control. The GEN 15 also includes a module for conditioning the output signals for electrical measurement purposes (voltage/charge conversion, precise AC voltage divider and IEPE sensor simulation).
ANA 15 Q module	The ANA 15 Q is used for measuring analog AC signals. It transfers the digital measurement data via a backplane to the GEN 15 or CCB 15 module for processing. All ANA 15 modules of a HERO™ work synchronously. Each ANA 15 Q represents one analog input channel. The module has integrated signal conditioners for IEPE sensors and piezoelectric sensors with charge output. It can receive analog signals from other signal conditioners, which are available as optional modules, via the backplane. The inputs are galvanically isolated.
PR 15 module	The PR 15 module is a signal conditioner for sensors that are based on a measurement bridge, e.g. piezoresistive acceleration sensors. The amplified analog signals are passed to an ANA 15 module, where they are converted to digital measurement data. The allocation of the PR 15 to a corresponding ANA 15 channel is carried out automatically by the HERO™ firmware or by qualified PC software. The sensors are connected by an interface box linked to the PR 15. Resistors can be added in the interface box for adding half-bridges or for adding shunt resistors.
UTB 15 module	The UTB 15 is a universal input board for sensors with a digital output. The UTB 15 should be used for direct communication with these sensors to calibrate them or to use them as sensors for measurement tasks. The module is based on a FPGA that can be used for programming various digital hardware interfaces and by means of which it can also be adapted in future to new interface types. The module also contains a NIOS processor that can be freely programmed for logical communication with the sensors. A power management unit is integrated for power supply to the connected sensors.
