PCM4_PCM5脉冲控制模块美***OMEGA欧米茄

将温度控制器或计算机的4至20 mA输入转换为时间比例输出

直接安装在Ω3至32 Vdc输入SSR上

支持单相或三相运行

50或60赫兹操作

Omega?PCM系列转换器模块有助于将4至20 mA输出转换为开/关时间比例输出。模块直接安装在SSR的输入终端上。在4至20 mA控制信号的转换器上提供螺纹端子。SSR的电源部分以标准方式连接到线路和负载。

带固态继电器的PCM模块向负载提供矩形时间比例（零点火）控制信号。因此，负载的平均功率与4至20 mA输入信号成比例。

PCM4_PCM5脉冲控制模块美***OMEGA欧米茄

Converts 4 to 20 mA Input from Temperature Controller or Computer to Time Proportional Output

Mounts Directly on an OMEGA 3 to 32 Vdc Input SSR

Supports Single or 3-Phase Operation

50 or 60 Hz Operation

The OMEGA? PCM series converter modules facilitate conversion of a 4 to 20 mA output to an on/off time proportioning output. The modules mount directly to the input terminals of an SSR. Screw terminals are provided on the converter of the 4 to 20 mA control signal. The SSR’s power section connects in standard fashion to the line and load.

The PCM module with a solid state relay provides a rectangular shape, time proportional (zero-fired) control signal to the load. Thus, the average power to the load is proportional to the 4 to 20 mA input signal.
