Modules with CAN or RS-485 interface | EPAD2 | CPAD2 | CPAD3 - 1

EPAD & CPAD Modules precision measurement of slow signals in rough environments, e.g. in an engine bay of a vehicle Key Features Extremely rugged Up to 24 bit A/D converter per channel Channel to channel isolation Channel to system isolation Flexible connectivity Flexible mounting High channel count by daisy-chaining distributed monitoring of slow signals in industrial plants high quality logging of environmental conditions quasi-static channel expansion of dynamic DEWETRON instruments EPAD2 and CPAD2/CPAD3 series modules can be daisy-chained to achieve a high channel count even over very long distances. Data output of CPAD2/CPAD3 series is available on CAN bus while EPAD2 series has a RS485 interface. For EPAD2 series there is an interface module (EPAD2-USB) available, which connects EPAD2 modules to a USB interface. Signal Conditioning The EPAD2 and CPAD2/CPAD3 series are multichannel modules and combine analog signal conditioning and A/D converter in an extremely rugged box. EPAD2/CPAD2 support 24 bit whilst CPAD3 modules support 20 bit A/D converter per channel, synchronized sampling, channel to channel and channel to system isolation. The sampling rate is 12 samples for EPAD2/CPAD2 modules and 100 samples per second for CPAD3 modules. The target applications are Modules with CAN or RS-485 Interface Dedicated Instruments Automotive Energy & Power Analysis Aerospace & Defense Tr a n s p o r t a t i o n G e n e r a l Te s t & M e a s u r e m e n t

EPAD & CPAD Modules Mounting Examples The EPAD2 and CPAD2/CPAD3 series modules are extremely rugged and offer a wide range of mounting options. DIN rail By ordering option XPAD-DIN-RAIL an adapter to snap EPAD2 and CPAD2/CPAD3 modules onto a DIN rail is included. A typical application for this is using EPAD2/CPAD2/CPAD3 inside 19” cabinets. Cable strap All modules have four trenches to provide maximum flexibility, most popular is fixing the modules by means of cable straps. A typical application for this is installing modules inside an engine bay of a vehicle. Bolt down All modules offer...
