The Bender A-Isometer IR470LY-40 (B91048007) from the Serie 470 range is an insulation monitoring device, supplied in Used condition. Working within the marine control system, it watches the insulation resistance of the ship’s ungrounded electrical networks to earth. It switches its relay contacts when the value drops below the response level. The response value range is 1 to 200 kΩ. It covers networks rated 0 to 690 V AC at 50 to 400 Hz and runs from a 230 V AC supply. Relay contacts are rated 250 V AC, 5 A, and the unit runs software D24 V1.5.
