Description
The PGR-6200 Motor Protection Relay offers enhanced motor protection and metering to provide diagnostic and troubleshooting capabilities for critical process motors. The PGR-6200 is used to provide current- and temperature-based protection, metering, and data logging for three-phase low- voltage medium-horsepower induction motors. This relay is ideal for retrofitting and upgrading motor protection using existing CTs. See the PGK Family of Panel Mount Adapter Kits to replace common obsolete relays. Motor Protection Relay Three ac-current inputs Earth-leakage-CT input Programmable digital input 24-Vdc source for digital input Programmable 4 – 20-mA analog output Temperature-sensor input, 100- Ω-Platinum RTD or PTC Three programmable output relays Local RS-232 communications, optional Network Communications PC-interface software 4 line x 20 character backlit LCD display Keypad for programming and display selection
4 LEDs; 1 user programmable
The PGA-0CIM Current Input Module is the interface between the PGR-6200 relay and the 5-A-secondary, 1-A-secondary, and sensitive current transformers. The PGA-0CIM is included with the PGR-6200 and can be surface or DIN-rail mounted.
