1756-OB16D ControlLogix 16 Pt 24V直流D/O模块

Allen-Bradley 1756-0B1 6D是一个ControlLogix DC诊断输出模块.它有1 6个诊断输啊用，每组8个点子融合以每分为基础。您可以将安装在兼容ControlLogix机箱中的任何可用插槽中。但是，为此需要一个36位可拆卸接线 盒外壳(RTB)。RTB可以是1756年的TBCH或者1756年的TBS6H.在安装带有RTB的模块之前，务必将机箱和电源安装并接地。

这款1756-0B1 6D模块与其他输出模块具有以下共同特征:输出数据回声、多输出点密度、可配置点级输出状态、电子熔断以及隔离和非隔离输出模块。它还允许您配置模块的各种功能，特别是空载检测、输出验证检测、故障模式下的输出状态、程序模式下的输出状态、从程序状态到故障状态的转换以及诊断锁存。

的短行程诊断功能1756-0B1 6D模块180毫秒(最小)时为8安，120毫秒(最小)时为10安。 空载功能仅用于关断状态检测，输出验证仅用于导通状态检测。脉冲测试具有用户可配置的最大脉冲宽度。该模块还允许您配置每个点的故障状态和每个点的程序模式状态，其中默认设置为”关”，其他选项为“开” 和“保持最后状态”这个输出模块拥有19.2至30伏DC的工作电压范围和24伏DC电源电压类别.它还具有每点3 mA的最小负载电流、每点1 mA的最大关态漏电流和1.2V的DC(最大导通压降为2 A)。其背板电流在24V DC时为140 mA,在5.1V DC时为250 mA,背板总功率为4.64 W。其线性降额输出电流额定值在30摄氏度(80华氏度)时最大为2 A,在60摄氏度(140华氏度)时每点最大为1 A,每个模块的额定值在30摄氏度时最大为8 A,在60摄氏度时最大为4A。每点的浪涌电流1756-0B1 6D每个10 ms的模块为4A,每秒可重复-次。其组与组和用户与系统之间的隔离电压在2546V下测试了1秒，两者的最大持续交流电压均为250V。

它的输出延迟时间标称值为55s，从关到开最长为1 ms,标称值为630 s,从开到关最长为5 ms。工作温度范围为0至60摄氏度(32至140华氏度),储存温度为- 40至85摄氏度( 40至185华氏度)。

Allen-Bradley 1756-0B1 6D is a ControlLogix DC diagnostic output module. It has 16 diagnostic inputs, each group of 8 points fused on the basis of each score. You can install it in any available slot in a Controllogix-compatible chassis. However, a 36-bit detachable wiring box housing (RTB) is required for this purpose. The RTB can be TBCH of 1756 or TBS6H of 1756. Before installing a module with RTB, ensure that the chassis and power supply are installed and grounded.

The 1756-0B1 6D module shares the following characteristics with other output modules: output data echo, multiple output point density, configurable point level output states, electronic fusing, and isolated and non-isolated output modules. It also allows you to configure various functions of the module, especially no-load detection, output verification detection, output state in fault mode, output state in program mode, transition from program state to fault state, and diagnostic latches.

The short stroke diagnostic function of the 1756-0B1 6D module is 8 amps at 180 ms (minimum) and 10 amps at 120 ms (minimum). The no-load function is only used for off status detection, and the output verification is only used for on-status detection. The pulse test has a user-configurable maximum pulse width. The module also allows you to configure the fault state of each point and the program mode state of each point, where the default is set to “off” and the other options are “On” and “Hold Last” This output module has an operating voltage range of 19.2 to 30 volts DC and a 24 volt DC supply voltage category. It also has A minimum load current of 3 mA per point, a maximum off-state leakage current of 1 mA per point and a DC of 1.2V (with a maximum on-voltage drop of 2 A). The backplane current is 140 mA at 24V DC, 250 mA at 5.1V DC, and the total backplane power is 4.64W. Its linear derated output current ratings are up to 2 A at 30 degrees Celsius (80 degrees Fahrenheit), 1 A per point at 60 degrees Celsius (140 degrees Fahrenheit), and 8 A per module at 30 degrees Celsius and 4A at 60 degrees Celsius. The surge current at each point 1756-0B1 6D is 4A for each 10 ms module and can be repeated – times per second. The isolation voltage between the group and the user and the system was tested for 1 second at 2546V, with a maximum continuous AC voltage of 250V for both.

It has a nominal output delay time of 55s, a maximum of 1 ms from off to on, a nominal value of 630 s, and a maximum of 5 ms from on to off. Operating temperatures range from 0 to 60 degrees Celsius (32 to 140 degrees Fahrenheit) and storage temperatures from -40 to 85 degrees Celsius (40 to 185 degrees Fahrenheit).
