Measurement boards & mainframes
The robust RASdelta mainframe is available with 8 and 16 measurement board slots. RASdelta measurement boards can be exchanged, depending on the application. Due to its compact format and low weight, the hardware is suitable for mobile use and easy transport. The mainframe is resilient and temperature insensitive, due to the integrated fan. Existing sensors and electronics of the ROTEC RAS FireWire series are compatible with the RASdelta series. The integrated touch panel display enables you to operate the system as a data logger without a measuring laptop.
Trigger board

Speed board
With the RASdelta speed board, you record precise, multi-channel and digital speed measurement data for all transmission, control and auxiliary drive tests. It is the basis for torsional vibration analysis. The data is acquired via magnetic, angular equidistant scanning, an incremental encoder or a laser.
- 1 MHz per channel with two-channel operation
- 2 MHz with one-channel operation
- Internal pulse divider (optional/required, if > 2 MHz)
- Variable trigger levels from 0,3 V to 4,5 V
- Trigger on falling, rising or both edge
- Power supply for external electronics: +5 V and +12 V
- 5 W per channel
- short-circuit proof
Analog board 3,2 MHz
- 3 balanced input voltage ranges of 0,1 V, 1 V and 20 V
- AC and DC coupling
- ICP power source
Analog board 50 kHz
With the RASdelta analog board, you can measure analog quantities such as airborne and structure-borne noise, acceleration, temperature, displacement or pressure. These quantities can be used, for example, to determine the position of a sound source or to carry out detailed valve train or cylinder pressure investigations. The analog measurement data is acquired by equidistant sampling.
- 2 balanced input voltage ranges of 40 V and 80 V
- DC coupling
- no ICP power source
- 11 balanced input voltage range 20 V, 10 V, 5 V, 2,5 V, 1,25 V and 625 mV, 320 mV, 160 mV, 80 mV, 40 mV and 20 mV
- AC and DC coupling
- ICP power source
Temperature board
With the RASdelta temperature board, you record measurement data from resistance thermometers and thermocouples. The measurement of the oil temperature in vehicles is indispensable, especially for transmission tests.
- 8, with 6-800 Hz sampling rate per channel
- 4, with 6-1600 Hz sampling rate per channel
- 2-wire configuration for Pt100/1000 and thermocouples
- 4-wire configuration for Pt100/1000
- Pt100/1000
- Thermocouples type J (Fe/CuNi)
- Thermocouples type K (NiCr/CrA)
- Thermocouples type T (Cu/CuNi)
- Thermocouples 0,1°C
- Pt100/1000: 0,01°C
DMS board
The RASdelta strain gauge board is an integrated two-channel DC voltage amplifier for signal acquisition from strain gauge-based, piezoresistive, magnetoresistive or potentiometric transducers. These include force, torque, pressure, displacement and angle sensors or scales. A big advantage of the board is that you can do without additional measuring amplifiers.
- Burn-Out detection / line break
- 4-wire and 6-wire operation
- Automatic zero adjustment
- Compensation of the measuring lead resistance
CAN BUS board
- 2.0 A (11-Bit-Identifier) and
- 2.0 B (29-bit Identifier)
- Switchable CAN terminating resistor (120 Ohm)
- Built-in signal filtering and decoding engine

Cluster
You can modularly expand the number of channels by coupling the RASdelta front-ends to each other via the Ethernet and Sync interfaces. One of the front ends acts as master card and synchronizes the other devices in the cluster. The ROTEC software recognizes the RASdelta cluster as an extended front end with additional slots.
Data logger
With the additional data logger module, you can convert your RASdelta 08 or 16 front-end to a data logger for mobile use such as in motor vehicles, on motorcycles, in racings or for applications at sea. The RASdelta runs in data logger mode without a measuring laptop, whereby all functions for operating the system can be executed directly at the RASdelta front end. Touch operations on the display enables measurements to be configured and carried out. All configuration and measurement data are stored on a micro SD card with USB adapter and can later be transferred to a PC for evaluation.
