1 HY6504输入/输出模块1.1概述HY6504输入/输出模块(见图1)是一款既能控制外部的直流24V负载,并接收负载动作后传回的无源信号,同时又能对输入和输出部件及接线都可进行监测的新型模块。该模块具有对输入设备及接线和有源输出的外部连接的直流24V负载(如:声光报警器、有极性警铃、切换模块等)是否完好进行监测,即从控制器输出的P,G总线和24V外供电源线经该模块至24V负载间的连线只要有一根未接好或出问题,控制器就会报此模块的故障号。同样两根线,只要输入设备及接线有一根未接好或出问题,控制器也会报此模块的故障号。该输入/输出模块只能运用在直流30V
1 HY6504 I / O module 1.1 Overview The HY6504 I / O module (see Figure 1) is a passive, 24 V load that controls an external DC load and returns the load after it has been loaded. It also provides input and output components And wiring can be monitored by the new module. This module monitors the integrity of the 24 V DC loads (eg audible and visual alarms, polar alarms, switching modules, etc.) on the input device and the wiring and external connections to the active outputs, ie the P, G bus and 24V external power supply line through the module to the connection between the 24V load as long as there is a bad or a problem, the controller will report the module’s fault number. The same two lines, as long as the input device and wiring is not a good or a problem, the controller will report this module fault number. The input / output module can only be used in DC 30V
