1756-IG16 晶体管逻辑（TTL）输入模块

【产品详情】

 Allen-Bradley 1756-IG16是一款晶体管-晶体管逻辑（TTL）输入模块。要将 1756-IG16 连接到 ControlLogix 1756 机箱，您需要使用可拆卸接线端子外壳或 RTB。您可以使用 1756-TBNH 或 1756-TBSH RTB。使用此模块时，应注意TTL输入是反转的。也就是说，低真格式为 -0.2 至 0.8 低电压 = 真 = 开，或者如果输入在此范围内，则保证输入处于导通状态。如果介于 0.8 到 2.0 伏之间，则无法保证输入状态。如果电压在 2.0 到 5.5 伏之间，则保证输入处于关断状态。1756-IG16 模块的电压类别为 5 伏直流 TTL 源（其中低表示为真）。其工作电压范围为 4.5 至 5.5 伏直流电，最纹波为 50 毫伏。它在 5 V DC 时的标称输入电流为 3.7 毫安，在 5 V DC 时的最大输入电流为 4.1 毫安。在关断状态下，最大电压为 2 伏，而最大电流为 4.1 毫安。它在 5.1 伏直流电下的背板电流为 110 毫安，在 24 伏直流电下具有 2 毫安的背板电流，背板功率为 0.61 瓦。模块在 5.1 伏直流时的电流消耗，而 24 伏时的电流消耗为 2 毫安。60 摄氏度时的最大功耗为 1.4 瓦。在 60 摄氏度时，最大热耗散为 4.8 BTU/小时 螺钉到背板输入的延迟时间如下： 从“关闭”到“打开”，或 5 至 0 伏直流转换，标称硬件延迟为 270 微秒，最大为 450 微秒，加上用户可选择的滤波时间 0、1、 或 2 毫秒。当“开”到“关”或 0 至 5 伏直流转换时，它的标称硬件延迟为 390 微秒，最大为 700 微秒，加上用户可选择的滤波时间为 0、1、2、9 和 1 毫秒。

【英文介绍】

 The Allen-Bradley 1756-IG16 is a transistor-transistor logic (TTL) input module. To connect the 1756-IG16 to the ControlLogix 1756 case, you need to use either a detachable terminal housing or an RTB. You can use 1756-TBNH or 1756-TBSH RTB. When using this module, it should be noted that the TTL input is inverted. That is, the low truth format is -0.2 to 0.8 Low voltage = true = on, or if the input is in this range, the input is guaranteed to be on. If it is between 0.8 and 2.0 volts, the input status cannot be guaranteed. If the voltage is between 2.0 and 5.5 volts, ensure that the input is off. The voltage class of the 1756-IG16 module is a 5-volt DC TTL source (where low is true). Its operating voltage range is 4.5 to 5.5 volts DC with a maximum ripple of 50 millivolts. It has a nominal input current of 3.7 MA at 5 V DC and a maximum input current of 4.1 mA at 5 V DC. In the off state, the maximum voltage is 2 volts, while the maximum current is 4.1 mA. It has a backplane current of 110 mA at 5.1 volts DC and a backplane current of 2 MA at 24 volts DC with a backplane power of 0.61 watts. The current consumption of the module at 5.1 volts DC is 2 mA at 24 volts. The maximum power consumption at 60 degrees Celsius is 1.4 watts. At 60 degrees Celsius, with a maximum heat dissipation of 4.8 BTU/ hour, the delay time for the screw to the backplane input is as follows: from "off" to "on", or 5 to 0 V DC conversion, the nominal hardware delay is 270 microseconds, up to 450 microseconds, plus a user selectable filtering time of 0, 1, or 2 milliseconds. When "on" to "off" or 0 to 5 volt DC conversion, it has a nominal hardware latency of 390 microseconds, up to 700 microseconds, plus user selectable filtering times of 0, 1, 2, 9 and 1 millisecond.
