DESCRIPTION:

This multifunction protective relay has a synchronization option and a resistance temperature detector interface. It features a graphic display and comes in a compact case measuring 1/1 19". The relay includes 48 binary inputs and 21 binary outputs, as well as 4 power relays with 8 contacts and 1 watchdog contact. It is equipped with a phase current transformer for precise monitoring.

The relay supports a supply voltage range of DC 60V to 125V and has a trigger level binary input of DC 19V. It can be easily mounted flush using screw terminals and supports English language for user convenience. The frequency compatibility is 50/60HZ, following IEC/ANSI standards, and it can be used in any region worldwide. The relay has a system port (Port B) for IEC 61850 with 100 Mbit Ethernet connectivity. It also features a Digsi 4/modem port (Port C) with RS485 interface. The relay offers various metering functions and fault recording functionality, including TOC+DIRECT, TOC+ phase overcurrent (50/51), reverse interlocking independent of phase rotation, ground overcurrent (50N/51N), and directional time overcurrent (67/67N with 50N/51N). It also supports phase rotation (47), overload protection with 2 time constants (49), trip circuit supervision (74TC), breaker failure protection (50BF), cold load pickup, inrush blocking, negative sequence (46), and lock out (86). The relay also provides synchronization capability for precise timing and coordination of electrical systems. It is a reliable and versatile solution for various protective relay applications.
