70EA05A-E 输入/输出模块也称为控制模块，在火灾报警联动系统中扮演着重要的角色。它不仅可以根据系统要求输出信号，使被控设备执行相应动作，还可以接收设备的反馈信号，向主机报告。例如，市场上的输入输出模块可以提供一对无源常开/常闭触点用以控制被控设备，部分厂家的模块还可以通过参数设定，设置成有源输出（如海湾GST-LD-8301）。

请问如何配置输出模块？

确保输出电流的大小能满足自动状态下需启动最多设备时所需的电流即可。

确保线路满载时末端设备电压足够驱动设备。

当采用了楼层显示时，因其工作电流和报警电流都远远大于其他设备，则需另外配置专供其使用的电源盘，并布楼层显示电源专线。

每块电源盘都要配备一组蓄电池作为备用电源，主机主板也要配备一组蓄电池作为备用电源。

70EA05A-E 输出模块的作用是接收PLC控制器处理过的数字信号，并把它转换成现场执行部件能接收的信号，用来控制接触器、电磁阀、调节阀、调速装置等，控制的另一类负载是指示灯、数字显示器和报警装置等。

为了提高抗干扰能力，一般的输入/输出单元都有光电隔离装置。在数字量IO模块中广泛采用由发光二极管和光电三极管组成的光电耦合器，在模拟量IO模块中通常采用隔离放大器。

The 70EA05A-E input/output module, also known as the control module, plays an important role in the fire alarm linkage system. It can not only output signals according to system requirements, so that the controlled device can perform the corresponding action, but also receive the feedback signal of the device and report to the host. For example, the input/output module on the market can provide a pair of passive normally open/normally closed contacts to control the controlled device, and some manufacturers' modules can also be set to active output through parameter setting (such as Gulf GST-LD-8301).

How to configure the output module?

Make sure that the output current is sufficient to meet the current required when the most devices need to be started in the automatic state.

Ensure that the terminal device voltage is sufficient to drive the device when the line is fully loaded.

When the floor display is used, because its working current and alarm current are much larger than other equipment, it is necessary to configure a power panel specially for its use, and distribute the floor display power line.

Each power panel should be equipped with a set of batteries as a backup power supply, and the main board should also be equipped with a set of batteries as a backup power supply.

The function of 70EA05A-E output module is to receive the digital signal processed by the PLC controller, and convert it into a signal that can be received by the field executive parts, which is used to control the contactor, solenoid valve, regulating valve, speed regulating device, etc. Another type of load control is the indicator light, digital display and alarm device.

In order to improve the anti-interference ability, the general input/output units have photoelectric isolation devices. Photoelectric couplers composed of light-emitting diodes and phototriodes are widely used in digital IO modules, and isolation amplifiers are usually used in analog IO modules.
