F3221 984322102   数字输入模块

取决于系统型号的不同，有一个或两个由微处理器控制的中央模件。中央模件上有两个RS485接口，传输率可达57600bps。取决于系统型号的不同，有一个或两个用于串接、以太网或profibus-DP通讯的通讯接口模件。在故障情况下，中央模件产生一个看门狗信号，用来切除可测试(Testable)输出模件。一个或两个电源模件(24VDC/5VDC)，用来提供中央模件的5VDC操作电压和输入/输出模件的控制电压。安装在机架背面的电池，作为SRAM和中央模件上实时时钟的后备电源。三个24VDC配电模件，用于输入与输出的供电，同时具有保护(熔断)功能。数字与模拟信号输入和输出(I/O)模件使用的插槽，多 13 个槽位。1/O模件直接连到中央模件上，连接I/O总线所需的一切功能都集成在H41g中央模件中。整体式电缆托架。连接与断开 24VDC供电的辅助模件，用来给看门狗信号、熔断器、风扇运转监视及两台风扇供电。用于系统、1/O级与用户程序信息的诊断显示和2个LED。用于第二个中央模件快速存取的双口RAM。时钟与后备电池I/O总线逻辑及与I/O模件的连接安全看门狗电源监视，可测试(5V系统电压)。电池监视

Depending on the system model, there are one or two central modules controlled by microprocessors. There are two RS485 interfaces on the central module, with a transmission rate of up to 57600bps. Depending on the system model, there are one or two communication interface modules for serial, Ethernet, or profibus-DP communication. In the event of a malfunction, the central module generates a watchdog signal to cut off the testable output module. One or two power modules (24VDC/5VDC) are used to provide the 5VDC operating voltage of the central module and the control voltage of the input/output module. The battery installed on the back of the rack serves as a backup power supply for the real-time clock on the SRAM and central module. Three 24VDC distribution modules are used for input and output power supply, and also have protection (fuse) function. A maximum of 13 slots are used for digital and analog signal input and output (I/O) modules. The 1/O module is directly connected to the central module, and all the functions required to connect the I/O bus are integrated into the H41g central module. Integral cable tray. Connect and disconnect the auxiliary module for 24VDC power supply, used to provide power to the watchdog signal, fuse, fan operation monitoring, and two fans. Diagnostic display and 2 LEDs for system, 1/O level, and user program information. Dual port RAM for fast access to the second central module. The clock and backup battery I/O bus logic, as well as the connection to the I/O module, are monitored by the safety watchdog power supply and can be tested (5V system voltage). Battery monitoring
