The Yaoan YA-K102S Gas Detection Controller is a wall-mounted industrial controller designed to work with compatible Yaoan YA-D series gas detectors. It provides centralized monitoring of gas concentration and system status, making it suitable for fixed gas detection and early-warning systems in industrial environments.
The controller uses a clear digital display with indicator lights to show detector status and alarm concentration. When gas concentration reaches or exceeds the preset alarm threshold, the YA-K102S can generate sound, light and voice broadcast alarms, helping operators identify hazardous conditions quickly. Yaoan specifies a response time of up to 30 seconds for the controller system.
For detector connectivity, the YA-K102S supports one 4-20 mA input or one RS485 data input, making it suitable for a single-channel gas detection installation. It is compatible with Yaoan YA-D series detectors and supports communication distances of up to 1200 m under the specified cable configuration.
The controller also features two passive relay contact outputs, allowing external equipment such as exhaust fans, solenoid valves or other safety devices to be activated when preset conditions are met. Its internal microprocessor handles detector signal sampling, real-time calculations, fault detection, power management, display control and alarm functions.
According to the supplied product sheet, the YA-K102S series is also available with optional battery-backup configurations and can support additional functions such as LoRa communication and SMS notification depending on configuration. These options should be confirmed for the exact unit supplied.
