Digital Data Collector with RS485 / RS232 Interface

Digital Data Collector

DDC-32 is a standalone Digital data collection unit for collecting field digital data. It can take upto 32 digital inputs with each input having optical isolation.0-5V or 0-12V or 0-24V DC can be connected to digital input.

DDC-32 periodically scans the digital inputs and sends the scanned data on RS232 port. The unit can be programmed to scan the digital inputs at different durations ranging from once in 10 ms upto 10 seconds in steps of 10 ms. Scanning is activated/deactivated through separate START SCAN and STOP SCAN commands. The DDC-32 reads data at specified scan period and dumps data out as a six byte streams and a one byte header and one byte checksum.

A separate application software which provides a GUI to interact and collect data from DDC-32, is available. The software allows data collection and storing in a file that can be read into EXCEL spread sheet for further analysis. A separate DLL also is provided, to help users to integrate DDC with their application software.

CUSTOM VERSIONS OF Digital Data Collector can be designed to delver data on different interfaces such as Serial port/ Parallel port/ Ethernet Interfaces.
