The DAT71210-HR is a high-voltage reed relay designed for demanding applications requiring exceptional isolation and low leakage current. This 10 kV isolation relay features rhodium contacts that provide low contact resistance while maintaining high reliability in sensitive test and measurement circuits. The relay operates with coil voltages of 5V, 12V, or 24V DC, with a must-operate voltage of 3.7–9 V DC (depending on coil selection) and a must-release voltage of 0.5–1.25 V DC. Key electrical characteristics include a maximum switching voltage of 1000 V DC, maximum switching current of 3 A DC, and an insulation resistance of 1×10¹4 O minimum (contact to all terminals), making it ideal for cardiac defibrillators, high-voltage power supplies, and precision test equipment where low leakage and high isolation are critical.
