The Measurable difference.

CPAD / EPAD Modules

Multi-channel A/D converters with CAN or RS485 interface

External, multi-channel CPAD3/CPAD2/EPAD2 modules combine analog signal conditioning and A/D converter in an extreme rugged box. Available with CAN or RS485 interface.

Used for precision data acquisition of slow signals in rough environments, e.g. in an engine bay of a vehicle, high quality data logging of environmental conditions or expansion of dynamic DEWETRON instruments with 12 or 100 Hz channels.

 

Different external, multichannel CPAD and EPAD modules can be connected and combine analog signal conditioning and A/D converter in an extreme rugged box

CPAD3 Modules

CPAD3 series are multi-channel modules and combine analog signal conditioning and A/D converter in an extremely rugged box. Each of the 8 measurement channels has its own A/D converter with a 100 Hz sampling rate. They have a standard CAN interface for data output and stand out with high galvanic isolation of 1500 V and a very low-noise 20-bit A/D converter per channel.

CPAD2 Modules

CPAD2 modules provide the measurement data via high-speed CAN, the same as CPAD3 series. But in comparison to CPAD3, they have a 24 bit multi-channel AD converter with 12 Hz sampling rate and offer 350 V galvanic isolation.

EPAD2 Modules

EPAD2 modules are 24 bit multi-channel AD converts that provide the data via RS-485 interface. With 12 Hz sampling rate and 350 V galvanic isolation. For EPAD2 series there is an interface module – EPAD2-USB– which converts the RS485 data to USB. DEWETRON systems have an EPAD2 interface, for simply connecting EPAD2 modules as static channel expansion by a single cable.
