Multi channel A/D converter with CAN or RS 485 interface

The externally connectable, multi-channel CPAD/EPAD module is a module that integrates analog signal conditioning and A/D conversion into an extremely solid box, with CAN or RS485 interfaces.

It is used to accurately collect slow signals in complex environments, such as in the engine compartment of a vehicle. with twelve to 100Hz The speed of each channel is taken as DEWETRON The expansion of the instrument records data with high quality.

CPAD3 module

CPAD3 is a multi-channel module and integrates analog signal conditioning and A/D conversion in an extremely solid box. Each of the eight measurement channels has a 100Hz sampling rate A/D converter.  

Product features

Very low noise 20 bit A/D converter per channel

1500 V high current isolation

Data output standard CAN interface

CPAD2 module

Like CPAD3 series, CPAD2 series transmits data through high-speed CAN bus. However, compared with CPAD3, it uses a 24 bit A/D converter with a sampling rate of 12Hz and provides 350V isolation.

name		passageway	Sample rate [KS/s]	Interface	Voltage range
CPAD2-V8		8 ISO	12 / 24	CAN 2.0B	±50v
CPAD2-TH8		8 ISO	12 / 24	CAN 2.0B
CPAD2-LA8		8 ISO	12 / 24	CAN 2.0B
CPAD2-RTD8		8 ISO	12 / 24	CAN 2.0B

EPAD2 module

EPAD2 has a 12Hz sampling rate 24 bit A/D converter, which transmits data through RS485 bus and is isolated by 350V. In EAPD2 series, there is an interface module EPAD2-USB, which converts RS485 data into bit USB. Each DEWETRON system has an EPAD2 interface, and only one cable is needed to turn EPAD2 into the static channel expansion of the system.
