1756-OB16IEFS 直流数字模块 具有电子保护和快速输出
【产品详情】
Allen-Bradley 1756-OB16IEFS 是一款 ControlLogix 直流数字模块,具有电子保护和快速输出。它有 16 个定时、高速、独立隔离、电子熔断输出。这是唯一可以在远程机箱中使用运动轴输出凸轮 (MAOC) 指令的模块。它也是唯一可以在此功能中接收输出数据的函数。它是一个 CIP Sync 从站设备,使用 CIP Sync 进行调度和时间戳。只有当机箱具有可拆卸接线端子外壳 (RTB) 时,它才能安装在机箱上,RTB 可以是 1756-TBCH 和 1756-TBS6H。
该模块还为 CIP 同步时间中的输出 0 至 15 提供定时输出控制。它还支持以至少 5μs 的间隔进行调度。
1756-OB16IEFS 模块的浪涌先导工作电流为 4 A,其工作电压范围为 10 至 30 V DC,电压类别为 12/24 V DC 灌电流/拉电流。其5.1 V时的电流消耗为320 mA,24 V时的电流消耗为3 mA。该模块的总背板功率为 1.7 W,最大关断状态泄漏电流为每点 < 0.1 mA,浪涌电流为 4 A,每点 10 ms,每 2 秒可重复一次,最大导通状态压降为 0.4 V DC (2 A) 和 0.2 V DC (1 A)。其每点的最大电流在 45 摄氏度时为 2 A(最多 4 个通道),在 60 摄氏度时为 1 A,而每个模块的最大电流在 60 摄氏度时为 16 A(每个通道最大为 1 A),在 45 摄氏度时为 8 A(每个通道最大为 2 A)。该器件的最小负载电流为每点 1 mA,连续隔离电压为 250V。
它具有标称 14μs 的意外输出延迟时间,从关断到打开的最大输出延迟时间为 23μs,反之亦然。该模块的脉宽调制 (PWM) 周期时间为最小 1 ms/最大 1 小时,PWM 导通时间为最小 200 μs/最大 1 小时,PWM 导通时间精度为 +/- 20 μs。
可以在模块中配置以下内容:故障模式下的状态(保持最后状态、打开或关闭)、故障模式的持续时间(1、2、5、10 秒、永远)、故障模式持续时间后的最终状态(打开或关闭)以及程序模式下的状态(保持最后状态、打开或关闭)。默认情况下,所有选项都具有“关闭”选项,但故障模式持续时间除外,其默认值为“永久”。

【英文介绍】
The Allen-Bradley 1756-OB16IEFS is a ControlLogix DC digital module with electronic protection and fast output. It has 16 timing, high-speed, individually isolated, electronically fusing outputs. This is the only module that can use motion shaft output CAM (MAOC) instructions in a remote case. It is also the only function that can receive output data in this function. It is a CIP Sync slave device that uses CIP Sync for scheduling and time stamping. It can only be mounted on a chassis if it has a removable terminal housing (RTB), which can be 1756-TBCH and 1756-TBS6H.
The module also provides timing output control for outputs 0 to 15 in CIP synchronization time. It also supports scheduling at intervals of at least 5μs.
The 1756-OB16IEFS module has A surge pilot operating current of 4 A with an operating voltage range of 10 to 30 V DC and a voltage class of 12/24 V DC feed/pull current. Its current consumption is 320 mA at 5.1 V and 3 mA at 24 V. The module has A total backplane power of 1.7 W, A maximum turn-off leakage current of < 0.1 mA per point, A surge current of 4 A, 10 ms per point, repeatable every 2 seconds, and a maximum on-state voltage drop of 0.4 V DC (2 A) and 0.2 V DC (1 A). Its maximum current per point is 2 A at 45 ° C (up to 4 channels) and 1 A at 60 ° C, while the maximum current per module is 16 A at 60 ° C (up to 1 A per channel) and 8 A at 45 ° C (up to 2 A per channel). The device has a minimum load current of 1 mA per point and a continuous isolation voltage of 250V.
It has a nominal unexpected output delay time of 14μs and a maximum output delay time of 23μs from off to on and vice versa. The pulse width modulation (PWM) cycle time of the module is a minimum of 1 ms/ a maximum of 1 hour, the PWM on-time is a minimum of 200 μs/ a maximum of 1 hour, and the PWM on-time accuracy is +/ -20 μs.
The following can be configured in the module: the state in failure mode (hold last, on or off), the duration of failure mode (1, 2, 5, 10 seconds, forever), the final state after failure mode duration (on or off), and the state in program mode (Hold last, on or off). By default, all options have an "Off" option except for the failure mode duration, which defaults to "Permanent."
