Operation & Interface Description
DIP Switch Configuration
The CS-733 uses intuitive DIP switches for system configuration, eliminating the need for any software tools. Each switch position corresponds to different function settings, including control mode selection, encoding settings, and learning function activation.
Engineers can quickly adjust the device's operating mode according to application requirements. The device supports momentary mode (press to trigger, release to reset), self-locking mode (press to toggle state), interlock mode (multiple channels mutually exclusive control), and delay mode (timed automatic shutdown).
Terminal Wiring
The relay output terminals feature a standard screw terminal design for secure and reliable wiring. Each relay group provides normally open (NO), normally closed (NC), and common (COM) contacts, facilitating connection to different types of loads. The terminals are clearly labeled and come with wiring instructions, allowing even first-time installers to complete correct wiring quickly.
The power input terminal features reverse polarity protection, safeguarding the device from damage due to incorrect wiring. The antenna interface is a standard SMA or other common interface, supporting the replacement of high-gain external antennas to extend the control distance.
Performance Testing and Verification
The CS-733 has undergone rigorous performance testing to ensure reliability in various real-world application environments. The following data is derived from laboratory tests and field application feedback.

Distance Test Results
In an ideal open space environment, the CS-733 can achieve a maximum control distance of 120 meters. In practical applications, the distance can be affected by factors such as walls, metal obstacles, and interference from other wireless devices.
In an office environment, due to partitions and furniture obstruction, the effective distance is approximately 65 meters. In industrial plants, due to open spaces but metal equipment interference, the distance is about 85 meters. In underground parking lots, due to the significant impact of reinforced concrete structures, the effective distance is approximately 45 meters.
