7sr1003 relay: The Reyrolle 7SR10 Argus overcurrent and earth shortcoming hand-off is a mathematical overcurrent assurance hand-off expected as a minimal expense answer for conveyance and modern applications. The Reyrolle 7SR10 Argus overcurrent and earth issue transfer is created utilizing the most recent age of equipment innovation and is accessible in various variations relying upon the power supply, Binary info/paired result design, and information correspondence office. Housed in a 4U high, size 4 non-draw-out case and these transfers give security, observing, instrumentation, and metering with incorporated info and result rationale, information logging, and issue reports. Correspondence admittance to the hand-off usefulness is by means of a front USB port for nearby PC association or back electrical RS485 (discretionary) port for far off association.

• It has a Universal power supply proper for both AC and DC.
• 1A and 5A CT are selectable at the site. Fundamental correspondence conventions like MODBUS RTU and IEC 103 are accessible and they are likewise site selectable. Transfer is outfitted with an adequate number of DI/DO for example up to 6 DI and 6 DO.
• 7SR1003 is intended for current-based insurance and 7SR1004 is accessible with extra voltage contributions to deal with voltage-based assurances. 7SR1005 is intended for engine insurance applications.
