1756-IM161 隔离数字输入模块

Allen-Bradley 1756-IM16I是一个交流数字输入模块。它有16个单独隔离的输入，每个点隔离，并且您可以配置状态更改和输入过滤器时间。与1756 ControlLogix机箱兼容，它需要1756- tbs6h或1756- tbch 36针可拆卸端子排外壳(RTB)将其连接到机箱。1756-IM16I的工作电压范围为159至265伏交流电，最大浪涌电流为250毫安，电压类别为240伏交流电50/60赫兹。它的背板电流在5伏时为100毫安，在24伏时为3毫安，背板总功率为0.58瓦。模块在60℃时的最大功耗为5.8瓦，散热19.78 BTU/小时。当从关断到导通状态时，1756-IM16I有一个螺钉到背板输入延迟时间，反之亦然。从“关”到“开”，输入延迟时间是最大10毫秒的硬件延迟加上输入滤波器时间(用户可选择1或2毫秒)，而从“开”到“关”，它是最大8毫秒的硬件延迟时间加上输入滤波器时间(用户可选择9或18毫秒)。模块在关机状态下的最大电流为2.5毫安，该状态下的最大电压为40伏交流电。在导通状态下，电流范围从5毫安(159伏交流，60赫兹)到13毫安(265伏交流，60赫兹)。另一方面，导通状态电压范围各不相同，它们是:159-265伏交流电，47-63赫兹，30摄氏度，所有通道打开;159-265伏交流电，47-63赫兹，40摄氏度，8点打开;159至253伏交流电，47-63赫兹，45摄氏度，所有通道打开;159至242伏交流电，47-63赫兹，60摄氏度，所有通道打开。

The Allen-Bradley 1756-IM16I is an AC digital input module. It has 16 individually isolated inputs, per point isolation, and you can configure a change of state and the input filter times. Compatible with the 1756 ControlLogix chassis, it requires either the 1756-TBS6H or 1756-TBCH 36-pin removable terminal block housing (RTB) to connect it to the chassis. The 1756-IM16I’s operating voltage range is from 159 to 265 Volts AC, maximum inrush current is 250 milliamps, and the voltage category is 240 Volts AC 50/60 Hertz. It has a backplane current of 100 milliamps at 5 Volts and 3 milliamps at 24 Volts, with a total backplane power of 0.58 Watts. The module has a maximum power dissipation of 5.8 Watts at 60 Degrees Celsius and a thermal dissipation of 19.78 BTU/hour. The 1756-IM16I has a screw to backplane input delay time when going from an off to on state, and vice versa. From ‘off’ to ‘on’, the input delay time is the hardware delay of 10 milliseconds max plus the input filter time (user-selectable at 1 or 2 milliseconds), while from ‘on’ to ‘off’, it is the hardware delay time of 8 milliseconds max plus the input filter time (user-selectable at 9 or 18 milliseconds). The maximum current of the module during an off-state is 2.5 milliamps and 40 Volts AC is its maximum voltage at that state. During an on-state, the current ranges from 5 milliamps at 159 Volts AC, 60Hertz to 13 milliamps at 265 Volts AC, 60 Hertz. On the other hand, the on-state voltage range varies and they are: 159-265 Volts AC, 47-63 Hertz at 30 Degrees Celsius with all channels ON, 159-265 Volts AC, 47-63 Hertz at 40 Degrees Celsius with 8 points ON, 159 to 253 Volts AC, 47-63 Hertz at 45 Degrees Celsius with all channels on, and 159 to 242 Volts AC, 47-63 Hertz at 60 Degrees Celsius with all channels ON.
