1734-OE2C 转换为模拟输出信号 非隔离电流输出

【产品详情】

Allen-Bradley 1734-OE2C 具有 2 个单端和非隔离电流输出。其模块以单极模式运行，消耗 4 个字节，并产生 2 个数据字节。其 2 通道模拟输出模块将数字代码转换为模拟输出信号。模块分辨率为 13 位，范围为 0-21 mA。

在设置单个模式时，1734-OE2C 有 2 种模式可供选择，分别为 0-20mA 和 4-20mA（默认）。它的默认缩放点为 1638（4 mA）和 8191（20 mA）。每当发生断线时，该模型都会设置一个常规状态位。每当有断线或现场电源丢失时，通道指示灯就会闪烁红色。Allen-Bradley 1734-OE2C 在 25 摄氏度时的绝对精度为 0.1% 满量程。其随温度变化的精度漂移为 30 ppm/摄氏度。它具有高达63%FS的阶跃响应，为24 μs，电流转换率为16 μs。1734-OE2C 的电压输出端具有 0-750 欧姆的阻性负载。5V DC 时，其点总线电流为 75 mA，功耗为 1.23 W。1734-OE2C 的散热为 4.19 BTU/Hr，隔离电压为 50V，连续测试可承受 2200V 直流电，持续 60 秒。它的外部直流电源电压为24V DC，标称电压范围为10-28.8V DC。它在 24V DC 时提供 70mA 的电流，其中包括 20mA 的输出。1734-OE2C 配有 4 个按键开关位置，尺寸为 56 x 12 x 75.5 mm。1734-OE2C通常

用于驱动调节最终控制元件（FCE），如控制阀、变频驱动器（VFD）、阻尼器、百叶窗和其他类似设备。它还可用于重新传输模拟数据，供数据记录器或记录仪、面板仪表、累加器、信号转换器和隔离器使用。

安装 1734-OE2C 和整个 POINT I/O 系统时，建议使用镀锌、镀黄铬钢 DIN 导轨。这种类型的DIN导轨具有更高的耐腐蚀性，因为POINT I/O模块接地通过DIN导轨连接。DIN导轨由非导电材料制成，材料受腐蚀、氧化影响很大，可能导致间歇性接地连接。

【英文介绍】

The Allen-Bradley 1734-OE2C has 2 single-ended and non-isolated current outputs. Its module runs in unipolar mode, consumes 4 bytes, and produces 2 bytes of data. Its 2-channel analog output module converts digital code into analog output signals. The module resolution is 13 bits and ranges from 0 to 21 mA.

When setting a single mode, the 1734-OE2C has 2 modes to choose from, 0-20mA and 4-20mA (default). Its default zoom points are 1638 (4 mA) and 8191 (20 mA). The model sets a regular status bit whenever a line break occurs. The channel indicator blinks red whenever there is a disconnection or field power loss. Allen-Bradley 1734-OE2C has an absolute accuracy of 0.1% full scale at 25 degrees Celsius. Its accuracy drifts with temperature to 30 ppm/ C. It has a step response of up to 63%FS at 24 μs and a current conversion rate of 16 μs. The 1734-OE2C voltage output has a resistive load of 0-750 ohms. At 5V DC, the point bus current is 75 mA and the power consumption is 1.23 W. The 1734-OE2C has a heat dissipation of 4.19 BTU/Hr, an isolation voltage of 50V, and can withstand 2200V DC for 60 seconds in continuous testing. It has an external DC supply voltage of 24V DC and a nominal voltage range of 10-28.8V DC. It delivers 70mA of current at 24V DC, which includes 20mA of output. The 1734-OE2C is equipped with 4 key switch positions and measures 56 x 12 x 75.5 mm. 1734-OE2C usually

Used to drive and regulate final control elements (FCE) such as control valves, variable frequency drivers (VFDS), dampers, shutters, and other similar devices. It can also be used to retransmit analog data for use with data loggers or recorders, panel meters, accumulators, signal converters, and isolators.

When installing the 1734-OE2C and the entire POINT I/O system, galvanized and chrome-plated steel DIN rails are recommended. This type of DIN rail has higher corrosion resistance because the POINT I/O module is grounded through the DIN rail connection. DIN guides are made of non-conductive materials that are highly affected by corrosion and oxidation, which can lead to intermittent ground connections.
