Premium Quality Industrial Sensor Component ACT20X-AI-2AO-S

The Weidmüller ACT20X-AI-2AO-S is an intrinsically safe isolating converter (signal conditioner) from the ACT20X series[citation:1]. It features 2-channel operation, accepting analog current signals (typically 4...20 mA) from the hazardous area (Ex zone 0, 1, 2) and transmitting them to the safe area[citation:1]. The device provides galvanic isolation between input, output, and power supply to ensure signal integrity and system safety.
