Overview
WCC Lite is a single-box device not requiring any vendor specific power supply or other components which can work as standalone device for application as protocol converting, mini RTU without I/O’s, datalogger, etc. WCC Lite is ideal for retrofit projects – as its small footprint allows to fit it into any existing cabinet, while its wide variety of supported protocols and possibility for converting them to each other gives a perfect fit. Additional DI and relay output allows to send information to the SCADA system about power outages and indicate errors on cabinet doors or to use as simple single command.
Due to integrated modem feature WCC Lite with smallest in the market footprint allows to switch from existing cabling or radio infrastructure to mobile connectivity. WCC Lite has ideal set of features to become as a networking router of small sites including routing, firewall and VPN features. High bandwidth of Ethernet and 4G allows to integrate video surveillance traffic or IED’s remote access for configuration, COMTRADE files and other needs.
WCC Lite can be used as a small RTU in secondary substations, renewable power plants, and other places with the need to collect and deliver data from various field equipment to SCADA, DMS or CloudIndustries.eu web SCADA platform. To read more about mini RTU with I/O’s click here.
