It works with Oeabt OBS-P1 and compatible current/pulsedriven actuators.

It remains closed by default and opens only when a control pulse is received. Speed and frequency are adjustable via the OBS-C1 controller (sold separately).The OBS-C1 controller drives and controls one channel of optoelectronic shutter or solenoid devices. A toggle switch powers the controller on/off. It connects to the OBS-P1 and other compatible actuators.Controller Main Menu (full manual available upon request): Mode: Manual, Auto, External TriggerShutter Settings: Set on/off durations in 100 ms steps (multiples of minimum duration)Display: Adjust brightness and sleep timeoutThe shutter stays open if the control voltage is maintained above the threshold; it closes when voltage drops below the threshold.Multiple units can be linked via trigger I/O for synchronized or asynchronous multi-channel operation.AssemblyApplication ExamplesEngineering DrawingsOBS-P1 Engineering DrawingOBS-C1 Engineering Drawing
