The isolation arrangement limits the propagation of ground-potential differences and electrical interference between individual measurement channels. Signal conditioning and noise filtering are provided before analog-to-digital conversion to maintain stable measurement data.\u003c\/p\u003e\n\u003cp\u003eThe module supports up to 16 input channels covering voltage, 4-20 mA current, thermocouple, RTD, digital, and pulse signal types.
