BENDER INC.

IR425-D4-2

ISOLATION MONITORING DEVICE

ART.NO: B71036402

ISOMETER® IR425-D4

• GROUND-FAULT MONITORING DEVICE FOR AC AND DC IT SYSTEMS

• APPLICATION CONTROL CIRCUITS

• ACCORDING TO IEC 61557-8

• TWO SEPARATELY CONFIGURABLE RESPONSE VALUES

• MULTI-FUNCTIONAL LC DISPLAY

THE ISOMETER® OF THE IR425 SERIES IS DESIGNED TO MONITOR THE INSULATION RESISTANCE OF UN­GROUNDED AC/DC CONTROL CIRCUITS (IT SYSTEMS) 0…300 V. DC COMPONENTS EXISTING IN AC/DC SYSTEMS DO NOT INFLUENCE THE OPERATING CHARACTERISTICS. AN EXTERNAL SUPPLY VOLTAGE ALLOWS DE-ENERGIZED SYSTEMS TO BE MONITORED TOO.

FEATURES: 

• INSULATION MONITORING FOR AC/DC CONTROL CIRCUITS 0…300 V

• TWO SEPARATELY ADJUSTABLE RESPONSE VALUES

• PRESET FUNCTION (AUTOMATIC SETTING OF BASIC PARAMETERS)

• CONNECTION MONITORING SYSTEM/EARTH

• LEDS: POWER ON, ALARM 1, ALARM 2

• INTERNAL/EXTERNAL TEST/RESET BUTTON

• TWO SEPARATE ALARM RELAYS (ONE CHANGEOVER CONTACT EACH)

• N/O OR N/C OPERATION, SELECTABLE

• FAULT MEMORY BEHAVIOUR, SELECTABLE

• SELF MONITORING WITH AUTOMATIC ALARM

• MULTI-FUNCTIONAL LC DISPLAY

• ADJUSTABLE RESPONSE DELAY

• TWO-MODULE ENCLOSURE (36 MM)

• PUSH-WIRE TERMINAL (TWO TERMINALS PER CONNECTION)

APPLICATIONS:

• AC/DC CONTROL CIRCUITS IN THE INDUSTRIAL SECTOR, MECHANICAL ENGINEERING, POWER PLANTS, ELEVATORS, AUTOMATION SYSTEMS ETC.

• AC/DC CONTROL AND AUXILIARY CIRCUITS IN ACCORDANCE WITH DIN EN 60204-1 “ELECTRICAL EQUIPMENT OF MACHINES”, IEC 60204-1, EN 60204-1

• AC/DC AUXILIARY CIRCUITS IN ACCORDANCE WITH DIN VDE 0100-725 (VDE 0100-725)

• SMALLER AC/DC IT SYSTEMS SUCH AS LIGHTING SYSTEMS
