The AQY210EHA is a 1-pole GU-E PhotoMOS Relay with I/O isolation voltage of reinforced 5000VAC. 1-channel (form-A) 4-pin type. Surface mount terminal. Reinforced insulation 5000V type, more than 0.4mm internal insulation distance between inputs and outputs. Con-forms to EN41003, EN60950 (reinforced insulation). Controls low-level analogue signals PhotoMOS relays feature extremely low closed-circuit offset voltage to enable control of low-level analogue signals without distortion.
