Module BL20-2AI-I(0/4...20MA)

The BL20-2AI-I(0/4...20MA) is a TURCK BL20 series electronic module with 2 analogue current inputs. The module mounts on a separate BL20 base, and the field signal is galvanically isolated from the module bus via an optocoupler.

• Inputs: 2 analogue current inputs, signal 0/4...20 mA
• Accuracy: input resistance <0.125 kΩ, maximum input current 50 mA
• Power: 24 VDC, field supply current ≤12 mA, module bus current ≤35 mA
• Connection: screw or tension-spring terminals (depending on the base)
• Environment: IP20, 0...+55°C

The module requires a separately ordered BL20 base (S3 or S4 series, with screw or tension-spring terminals) — it cannot be used without one. The electronics can be replaced without disconnecting the field wiring, since the connections stay on the base.

Complies with cULus requirements.
