Isolation Monitor Detects Electrical Hazards During Dynamic Operation

The SIM100 automotive-rated, isolation-monitoring safety device is capable of detecting potential electrical hazards during the dynamic operation of high voltage unearthed systems, such as electric and hybrid vehicles. The module is reportedly the first device of its kind capable of unambiguously detecting the electrical isolation state of a high voltage system while the system is active and operating, and experiencing large voltage variations. Said to be another first, the SIM100 detects both resistive leakages and capacitively stored energy that could be harmful to human operators. Communications are achieved with the host ECU via an isolated CAN 2.0B interface (500 kbit/s). The module has a wide input voltage of 5 V to 53 V, thereby accommodating most vehicle systems.  It provides a wide temperature range from –40°C to +105°C. The module was designed to ISO 6469-3:2011-12 / FMVSS 305. Peruse the datasheet at http://www.sendyne.com/Products/Sendyne%20SIM100MOD%20Datasheet%20V0.4.pdf
