1756-IF16 Communication module

MFR Multi Function Relays provide monitoring and protection for a wide range of power generation and distribution applications. Each of the MFR series protects for the designated faults, monitors and displays the generator or utility ac signals, includes one ANSI 74 alarm relay and 3 output relays, and is easily configured via the service interface.The MFR 13 provides voltage, current and power protection, and different packages are available for different applications: • MFR 13/GP package includes protection for over-/under-voltage, over-/underfrequency, voltage asymmetry, time-overcurrent (TOC), overload, reduced/reverse load, load imbalance, re-active power (loss of excitation), and power factor cosphi as well as monitoring for zero-voltage. • MFR 13/GPX package adds five additional configurable relay outputs and a synch-check relay function.

Other Woodward multi-function relays

—such as the MFR 2/3 and ESDR units— provide specialized protection, synchronization and monitoring functions. The MFR 15 provides voltage, current and power protection as well as automatic control and synchronization. Different packages are available for different applications: • MFR 15/SY package includes similar protection as the MFR 13/GP except monitoring for zero-voltage plus synchronization for one power circuit breaker, automatic control for real power and power factor cosphi. An 0/4– 20 mA analog signal could be used to feed an external power setpoint value to the control. Three freely configurable analog outputs and an pulse output for kWh complete this package: • MFR 15/SYN package adds load sharing. • MFR 15/SYN-I package adds a MOD bus RTU slave interface.

The MFR 2 control combines protection

 for both the generator and the utility with synchronization logic for two circuit breakers. It controls frequency, voltage, real generator power, power factor (cosphi), and load/VAR sharing. It also displays kWh, kVARh, operating hours, number of starts and maintenance calls. The MFR 2 includes 4 discrete alarm inputs, 4 freely configurable relay outputs, and features a synchroscope on the front panel. Two different packages offer flexibility. Æ Please request special versions from our sales department. (product spec 03248) The MFR 3 adds additional I/O's and a soft loading feature as well as pushbuttons for direct control on the front panel. The MFR 3 includes 12 discrete alarm inputs, 7 freely configurable relay outputs, and features a synchroscope on the front panel. Two different packages offer flexibility. Æ Please request special versions from our sales department. (product spec 37166) The ESDR 4 and ESDR 4T are three-phase current differential protection relays for generators, motors and, with the ESDR 4T, even transformers in unit connection. The currents flowing into the individual conductors are measured by means of current transformers at both sides of the protection object(s). Any two-phase of three phase short circuits and ground leakage's are recognized by the ESDR 4 and ESDR 4T as fault currents.
