Engineering Advantages

The wide 170–265VAC input range tolerates voltage fluctuations common in industrial power distribution. Eight channels in a single slot conserve rack space. The 2 mA off-state current prevents false triggering from leakage. Low 3.1 W heat dissipation reduces panel cooling requirements. At roughly 0.35 kg, the module adds minimal weight to the chassis. Withstands 30 g shock and 1.0 g vibration for reliable operation in high-vibration machinery environments.
