WG 25

环路供电电源

无源WG 25中继器电源由环路供电，用于在危险区域电流隔离2线电源线，以及双向传输4 … 20 mA和HART®信号。压降仅4.2 V，WG 25以最佳方式使用电源，使得所有常见2线变送器都可以连接。

与有源中继器电源相比，其价格和可靠性具有明显的优势。多通道系统仅需一个位于安全区域的中央电源，甚至不需要保护分隔。

事实

无集成电源，因而成本很低
无需交流电源，接线量减少，节省成本
无交流电源干扰
低功耗，外壳中无不必要的加热
保护分隔符合EN 61140标准：保护维护员工和后续设备免受过高电压影响
HART®传输：根据HART®规范双向点对点传输数字数据
通过EMC测试的RFI抑制和抗电涌性能：在电磁干扰下也能可靠地工作
最高可靠性：无维护工作，因而无相关成本

5年质保

HART®是HART通信基金会的注册商标
