This source is shared between channels in pairs, so only two independent current sources exist. Therefore, you can actively measure RTDs on a maximum of two channels at any one time.\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eWhat is the practical impact of selecting a 100ms integration time?\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003eChoosing 100ms provides the highest noise rejection (10 Hz), ideal for filtering out 50\/60 Hz AC interference in noisy plants. The trade-off is a slower channel update rate (~107ms), which is fine for slow processes like temperature but not for fast pressure control.\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eHow should I handle thermocouple cold-junction compensation in a panel?\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003eFor best accuracy, use the module's internal compensation for stable ambient temperatures. If the cabinet temperature fluctuates, connect a Pt100 sensor to a spare channel and assign it as the external reference for much more precise compensation.\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eCan I mix a 4-20mA and a ±10V signal on the same module?\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003eAbsolutely. Each of the four channels is independently configurable in TIA Portal. You can set Channel 0 for 4-20mA, Channel 1 for Pt100, and Channel 2 for ±10V simultaneously, maximizing the module's versatility.\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eThe spec mentions a \"burden of 820Ω max for 2-wire transmitters.\" What does this mean?\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003eThis is the total maximum loop resistance. It includes the wire resistance and the transmitter's internal impedance. If your loop resistance is higher, the 20mA supply may not be able to drive the transmitter, causing a low signal. Always calculate your loop resistance before installation.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e© 2025 Ubest Automation Limited.
