PCM4_PCM5脈沖控制模塊美***OMEGA歐米茄

將溫度控制器或計(jì)算機(jī)的4至20 mA輸入轉(zhuǎn)換為時(shí)間比例輸出

直接安裝在Ω3至32 Vdc輸入SSR上

支持單相或三相運(yùn)行

50或60赫茲操作

Omega?PCM系列轉(zhuǎn)換器模塊有助于將4至20 mA輸出轉(zhuǎn)換為開/關(guān)時(shí)間比例輸出。模塊直接安裝在SSR的輸入終端上。在4至20 mA控制信號(hào)的轉(zhuǎn)換器上提供螺紋端子。SSR的電源部分以標(biāo)準(zhǔn)方式連接到線路和負(fù)載。

帶固態(tài)繼電器的PCM模塊向負(fù)載提供矩形時(shí)間比例（零點(diǎn)火）控制信號(hào)。因此，負(fù)載的平均功率與4至20 mA輸入信號(hào)成比例。

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.

SPECIFICATIONS

Analog Input Signal: 4 to 20 mAdc

Note: Control signal cannot drop below 4 mAdc or improper operation may occur. Compliance Voltage Requirement:

Time Base: 3 cycle resolution 6.4 Vdc (320 Ω @ 20mA)

Ambient Temperature: 0 to 40°C (32 to 104°F)

Dimensions: 32 W x 45 L x 20 mmD (1.25 x 1.75 x 0.75")
