Philips BASS+ SHB3175 Wireless Headphones up to 12 Hours of Playtime - Matte Black

Isolate and amplify the weak control signal (only a few milliamps of current) by photoelectricity, and finally output a higher power control signal to directly drive the motor, contactor, solenoid valve, etc..
The response time is as low as milliseconds and there is no limit on the number of switches. It can directly replace traditional relays, reducing maintenance time and costs..
Photoelectric isolation is used between the input stage and the output stage, and the two stages are completely independent, which effectively avoids the instability caused by mutual interference of the system and effectively protects the output node of.
Made of high-quality electronic components, stable and reliable performance..
Hole punching and PCB module mounting are more convenient..

COMPACT RASPBERRY PI 4 POE HAT: Ideal for non-grounded installation, this NON-ISOLATED PoE HAT features optimized footprint. Must be used with a standards compliant IEEE 802.3af PoE or 802.3at PoE+ switch that complies with Section 33.4.1 for power sourcing equipment (PSE) electrical isolation. "Passive PoE" (DC 24V or 48V) is not standards compliant and may cause damage to equipment if connected improperly. Some Ubiquiti switches are not properly isolated and require isolated PoE HATs..
GROUND LOOPS WARNING: Do not use this device with grounded USB peripherals, HDMI displays, and attachments. Please use the professional PoE model with isolation transformer to prevent electrical loops. In non-controlled PoE applications, ALWAYS use the professional PoE model..
INTEGRATED PWM FAN CONTROLLER: Based on the EMC2301 SMBus compliant fan controller, this PoE HAT is fully programmable over I2C to control standard 4-pin PWM fans. Set user-space or device-tree based temperature or event triggers for complete fan control from off to maximum RPM. Fan speed tach also provides stall detection, spin-up control, and ramp rate control with 1% accuracy from 500-16K RPM..
VENTILATED CASE WITH FAN HIGHLY RECOMMENDED: Do not use this product in an enclosed case without acti....
