Each channel is digitized with 16‑bit resolution and transferred galvanically isolated to the controller. Open lead and overload conditions are detected and reported; LEDs indicate run\/error states. FIR\/IIR filters and limit monitoring can be enabled.\u003c\/p\u003e\n\n  \u003ch3\u003eKey Features\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003e2 differential current inputs, 4–20 mA\u003c\/li\u003e\n    \u003cli\u003eHigh resolution: 16‑bit;
