Calibration: Unit is factory programmed via microcontroller and/or trim pots for use with each corresponding laser shutter model, and in the case of large optic shutters, calibrated additionally for gravity orientation effects. Label on product denotes mating laser shutter model.
Shutter Compatibility: All our laser shutters can be driven with the CX4000B. In higher performance shutters, the ultimate performance, switching speeds, and repetition rates are typically achievable with the CX4000B through careful calibration.
OEM Integration Considerations:
Electrical Safety: The 24 VDC standard power input makes for simple electrical safety certification in integrated systems.
Control Signal & Connections: The input control signal can be TTL or up to 24 VDC. Positive polarity opens the shutter. Polarity markings are shown on mechanical drawing and PCB silkscreen labeling. The input is resistive, at about 2.4 KΩ through an opto-isolator LED with a 1 V drop. Your signal source must be able to source the required current, typically less than 2 mA at TTL voltages, or up to 10 mA from a 24 V PLC.
Output Power and Connections: The laser shutter controller outputs an inductive load waveform optimized to each shutter model. In general, 24 V is applied to the load for preset time, then the controller will use PWM to lower the voltage to a long-term hold level. The CX4000B has the added benefit of regulating the hold current, allowing for optimal performance throughout the shutter’s rated operating temperature range. The inductor is not part of the switching circuit, only an inductive load.
Power–Up Considerations: The user’s power supply should be able to surge current into the CX4000B surge capacitor on initial power up. In operation, the surge current needed to drive the laser shutter load comes from the capacitor. If the available power supply is of minimal current rating, a soft start buffer (current ramp) should be considered.
Connections and Operational Procedure: See mechanical drawing for mounting hole location and spacing, and connection polarities.
