EPAD2/CPAD2 modulesCPAD2 and EPAD2 Series Modules
The EPAD2 and CPAD2 series are multichannel modules and combine analog signal conditioning and A/D converter in an extreme rugged box. All have one 24 bit A/D converter per channel, synchronized sampling, channel to channel and channel to system isolation. The sampling rate is 12 samples per second and the target applications are
- precision measurement of slow signals in rough environments, e.g. in an engine bay of a vehicle
- distributed monitoring of slow signals in industrial plants
- high quality logging of environmental conditions
- quasi-static channel expansion of dynamic DEWETRON instrument
EPAD2 and CPAD2 series modules can be daisy-chained to achieve a high channel count even over very long distances. Data output of CPAD2 series is available on CAN-bus while EPAD2 series has a RS485 interface. For EPAD2 series there is an interface module – EPAD-BASE2 – which converts the RS485 data to USB, RS232 or CAN.
CPAD2CPAD2 series modules are rugged low-speed isolation amplifiers for CAN-bus. All have multiple input channels and a CAN interface for configuration and data transfer. EPAD2EPAD2 series modules are the same but use RS-485 instead of CAN. These modules are mainly used to add slow channels to DEWETRON dynamic data acquisition instruments. | Key features:
