IC693MDL752F 负逻辑输出模块 灌电流型输出点

☆型号：IC693MDL752F 负逻辑输出模块 灌电流型输出点

【产品详情】

IC693MDL752,5/24 伏直流 （TTL） 负逻辑输出模块具有 32 个负逻辑或灌电流型输出点（低电平有效），并使用 32 位离散 %Q 输出数据。输出分为四个独立的组（标记为 A 到 D），每组由 8 个输出组成（编号为 1 到 8），每个组都有其独特的共同点。它可以安装在任何具有 5 或 10 个 I/O 插槽基板的 90-30 系列可编程逻辑控制器 （PLC） 系统中。每个组公共都有用户 I/O 连接器，这些连接器带有两个引脚。这些连接器上的每个引脚都具有 3 安培的电流处理能力。在连接公共端时，建议连接到两个引脚，但对于需要高电流的应用（例如 3 到 4 安培之间）是必需的。

该IC693MDL752在两种模式下运行：晶体管-晶体管逻辑 （TTL） 和 12/24V 模式。在TTL模式下，每个输出都可以在+5 VDC上切换用户负载。在 12/24V 模式下，用户负载可在 +12 至 -24 VDC 范围内切换。此外，在每种模式（TTL 和 12/24V）下，输出点每个点的最大电流分别为 25 mA 和 0.5A。模块中的每个输出组（A 到 D）都可以在适合特定任务或应用程序的负载要求的操作模式下使用。A 组可应用于 TTL 负载任务，B 组可应用于 12 VDC 负载，而 C 组和 D 组可应用于 24 VDC 负载任务。然而，在混合模式（TTL和电感型负载）时，重要的是要认识到电噪声及其影响。

用户负载设备通过位于模块前面的两个 24 针公连接器连接到模块。右侧的连接器与 A 组和 B 组输出点连接，而左侧的连接器与 C 组和 D 组输出点连接。模块上的光耦合器在现场侧和逻辑侧之间提供背板隔离。该模块的顶部还具有 LED 指示灯，相应地标记每个输出，指示每个输出点的活动 （ON） 或非活动 （OFF） 状态。没有特殊故障或报警诊断的报告。

每个输出点都有一个内部上拉电阻。当输出点的场效应晶体管 （FET） 关断时，电阻旨在为 TTL 任务提供高逻辑电平。它通过将输出上拉至用户电源输入的正侧来实现这一点，对于TTL任务，该电源输入通常为+5V。停止 CPU 会强制关闭所有 32 个输出点，用户必须提供电源才能为负载提供电流。该模块使用用户提供的最小功率为输出设备提供栅极驱动。

【英文介绍】

The IC693MDL752,5/24 volt direct current (TTL) negative logic output module has 32 negative logic or perfusion type output points (active at low levels) and uses 32-bit discrete %Q output data. The outputs are divided into four separate groups (labeled A through D), each consisting of eight outputs (numbered 1 through 8), each with its own unique commonality. It can be installed in any 90-30 series Programmable logic controller (PLC) system with 5 or 10 I/O slot substrates. Each group has user I/O connectors with two pins. Each pin on these connectors has a current handling capacity of 3 amps. It is recommended to connect to two pins when connecting the common end, but is required for applications that require high currents (between 3 and 4 amps, for example).

The IC693MDL752 operates in two modes: transistor-transistor logic (TTL) and 12/24V mode. In TTL mode, each output can switch the user load on +5 VDC. In 12/24V mode, the user load can be switched between +12 and -24 VDC. In addition, in each mode (TTL and 12/24V), the maximum current at each point of the output point is 25 mA and 0.5A, respectively. Each output group in the module (A through D) can be used in a mode of operation appropriate to the load requirements of a particular task or application. Group A can be applied to TTL load tasks, Group B can be applied to 12 VDC loads, and Group C and Group D can be applied to 24 VDC load tasks. However, when in mixed mode (TTL and inductive type loads), it is important to recognize electrical noise and its effects.

The user load device is connected to the module via two 24-pin male connectors located on the front of the module. The connectors on the right are connected to group A and Group B output points, while the connectors on the left are connected to group C and Group D output points. The optical coupler on the module provides backplane isolation between the field side and the logical side. The top of the module also has LED indicators that mark each output accordingly, indicating the active (ON) or inactive (OFF) status of each output point. No special faults or alarm diagnoses were reported.

Each output point has an internal pull-up resistor. When the field-effect transistor (FET) at the output point is turned off, the resistance is designed to provide a high logic level for the TTL task. It does this by pulling the output up to the positive side of the user's power input, which is typically +5V for TTL tasks. Stopping the CPU forces all 32 output points to shut down, and the user must supply power to provide current to the load. The module provides the grid drive to the output device using the minimum power provided by the user.
