Signal Isolator, Universal Analog Input, 4-20mA/0-10V

This signal isolator 4‑20mA takes 4‑20mA, 0‑20mA, or 0‑10V inputs (25Ω) and outputs same types with current load ≥800Ω. Available in 1 or 2 channels, consuming <1W or <1.5W. As an analog isolator, it has ±0.1% accuracy, 10ms response, and ≤±1μA/10°C drift. This 4‑20mA isolator offers 1500VAC isolation, ripple ≤5mV, distribution ≥21V, and reverse protection. This signal isolator converter also includes impact protection and slow start. As an analog signal isolator 4‑20mA, it operates on 20‑40V DC, meets IEC 61326‑1, and measures 106.5×12.5×115mm. Ideal for universal analog signal conditioning.

Feature

• Response time: 10 ms (5× faster than 50 ms) ensures instant reaction for pressure and level control loops.
• Input impedance: 25 Ω (vs. typical 100 Ω) allows daisy-chaining extra devices without signal overload.
• Load capacity: up to 800 Ω for 4-20mA output drives heavier loads or longer runs than standard 550Ω.
• Reverse protection: ≤40V plus 20ms soft-start prevents damage from wiring errors and surges, reducing downtime.
• Distribution voltage: ≥21V at ≤30mA powers two-wire transmitters directly, eliminating external loop supplies.
• Power dissipation: <1W (1 channel) and <1.5W (2 channels) minimizes heat for dense mounting without active cooling.
