33
+The ELM4XXA(BMS) is solid state relays containing an AlGaAs infrared LEDs on the light emitting side (input side)
34
+optically coupled to a high voltage output detector circuit. The detector consists of a photovoltaic diode array and
35
+MOSFETs on the output side. The single channel configuration is equivalent to 1 form A EMR. The devices in a 4-pin
