RCM-1A/1B超短波无线电遥控模块是将高频模拟电路、收发天线和数字电路配对调好后,用环氧树脂灌封而成的混合集成器件,它具有微功耗、使用简便(无须任何调试)、外围元件少、输出电平高、体积小、性能稳定等特点,特别适应在湿度大和温差较大的恶劣环境下工作,其外形尺寸及引脚排列如图1所示。该模块按有效控制距离远近划分为Ⅰ型(10～15m)、Ⅱ型(20～30m)和Ⅲ型(35～45m)3种。 由RCM-1A/1B构成的报警电路如图2所示。其中无线
RCM-1A / 1B UHF radio remote control module is a hybrid integrated device which is made of epoxy resin after being paired with high-frequency analog circuit, transmitting / receiving antenna and digital circuit. It has micro-power consumption and easy to use Debugging), less external components, high output level, small size, stable performance and other characteristics, especially adapted to work in harsh environments with large humidity and large temperature difference. The overall dimensions and pin arrangement are shown in Fig.1. The module is divided into three types: type Ⅰ (10 ~ 15m), type Ⅱ (20 ~ 30m) and type Ⅲ (35 ~ 45m) according to the effective control distance. The alarm circuit formed by RCM-1A / 1B is shown in Fig.2. Among them wireless
