WCC Lite – mini RTU and gateway

Overview

WCC Lite is a single-box device not requiring any vendor specific power supply or other components and can work as stand alone device for application like protocol converter, mini RTU without I/O’s, datalogger and other. WCCLite is ideal for retrofit projects – is small footprint allows to fit into any existing cabinets, wide variety of protocols and support of conversion any to any gives perfect fit. Additional DI and relay output allow to send into SCADA system information about power outages and indicate errors on cabinet doors or use as simple single command.

Due to integrated modem feature WCCLite with smallest in market footprint allows to switch from existing cabling or radio infrastructure to mobile. WCCLite has ideal set of features to become as 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 sources, and other places with 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.
