You must use a temperature transmitter that converts the signal to 4-20mA or 0-10V first.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What does \"non-isolated\" mean for my wiring?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA: It means all 16 channels share a common electrical reference point (MANA). All your sensors must be grounded to the same potential to avoid measurement errors or damage.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: How do I power my 4-20mA sensors?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA: The module provides a 24V L+ supply. Connect the positive side of your 2-wire transmitter to this L+ terminal, and the signal wire to the analog input. It can power up to 16 sensors (400mA total).\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What is the difference between basic error and operational error?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA: Basic error (±0.25%) is the accuracy at a perfect 25°C lab condition. Operational error (±0.65%) includes the added effect of temperature changes in a real panel, giving you the true expected accuracy.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Why is the cable length limited to 200m?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA\u0026gt; This limit ensures signal integrity and accuracy. Longer cables increase electrical resistance and noise pickup, which can distort the small analog signals. For longer runs, consider using signal conditioners.\u003c\/p\u003e\n\u003cp\u003e© 2025 Ubest Automation Limited.
