Allen-Bradley 1746SC-IN04I 模拟输出模块
【产品详情】
1746SC-INO4I 是 Spectrum Controls 的模拟电流输出模块。该模块具有四 (4) 个隔离通道输出。1746sc-INO4I 占用 1746 输入/输出机箱中的一个插槽。1746sc-INO4I 在 5 伏特直流电下从背板上汲取 120 毫安的电流，但为了最大限度地减少背板上的电流负载，1746sc-INO4I 可以连接额定电压为 24 伏特直流电的外部电源。1746sc-INO4I 有一个 DIP 开关，用于指定模块是从背板还是外部电源获取电源。当 1746sc-INO4I 上的 DIP 开关设置为 RACK 位置时，模块从背板获取电源，而模块由外部 24 伏直流电源供电，DIP 开关应设置为 EXT 位置。
1746SC-INO4I 从背板获取 5 伏直流电源。当模块由外部供电时，此功耗额定值相同。该模块有一个可拆卸的 16 位接线盒，可容纳 Belden 8761 屏蔽双绞线电缆。1746SC-INO4I 的分辨率为 16 位，每次计数的电流为 366 纳安，每次计数的电压为 320 微伏。1746SC-INO4I 隔离通道模拟输出模型具有自动校准可编程限制和安全状态，750 伏直流光电隔离(通道到通道和现场接线到背板)。1746sc-INO4I 的额定热耗散最大为 4.5 瓦，所有 4 个并行通道的最大更新时间为 33.7 毫秒，阶跃响应时间为 1 毫秒。此外，1746sc-INO4I 是 UL/CUL I 类，2 区，
该模块的外观类似于实际的 SLC 500 模块。该模块具有四 (4) 个差分模拟输出通道，以 16 位分辨率提供 0-20 mA、0-21 mA、4-20 mA，每次计数 366 nA。该模块具有扩展的输出范围、自动校准、可编程限制和安全状态。该模块的数据能够格式化为 16 位二进制补码、缩放工程单位、缩放 PID、1746-NO4 格式和用户定义的比例计数。它在 25 度时的精度为满量程的 0.08%。摄氏度和 0.15% 在 60 度。摄氏度。

【英文介绍】
The 1746SC-INO4I is an analog current output module from Spectrum Controls. The module has four (4) isolated channel outputs. The 1746sc-INO4I occupies a slot in the 1746 input/output chassis. The 1746sc-INO4I draws 120 milliamps of current from the backplane at 5 volts DC, but to minimize the current load on the backplane, the 1746sc-INO4I can be connected to an external power supply rated at 24 volts DC. The 1746sc-INO4I has a DIP switch that specifies whether the module obtains power from the backplane or an external power supply. When the DIP switch on the 1746sc-INO4I is set to RACK position, the module obtains power from the backplane, and the module is powered by an external 24 volt DC supply, the DIP switch should be set to EXT position.
The 1746SC-INO4I obtains 5 V DC power from the backplane. This power rating is the same when the module is powered externally. The module has a removable 16-bit junction box that can accommodate Belden 8761 shielded twisted pair cable. The 1746SC-INO4I has a resolution of 16 bits, a current of 366 nanoamps per count, and a voltage of 320 microvolts per count. 1746SC-INO4I Isolated channel analog output model with auto-calibrated programmable limits and safe state, 750 volts DC opto-electrical isolation (channel-to-channel and field wiring to backplane). The 1746sc-INO4I has a rated heat dissipation of up to 4.5 watts, a maximum update time of 33.7 milliseconds across all four parallel channels, and a step response time of 1 millisecond. In addition, 1746sc-INO4I is UL/CUL Class I, Zone 2,
The module looks similar to the actual SLC 500 module. The module has four (4) differential analog output channels providing 0-20 mA, 0-21 mA, 4-20 mA at 16-bit resolution, each counting 366 nA. The module has an extended output range, automatic calibration, programmable limits and safe status. The module's data can be formatted into 16-bit binary complement, scaled engineering units, scaled PID, 1746-NO4 format, and user-defined proportional counts. It has an accuracy of 0.08% of full scale at 25 degrees. Celsius and 0.15% at 60 degrees. Degrees Celsius.
