产品详情资料：
YPN107A YT204001-DM数字输入模块包括热备用功能，可在线更换故障模块。与所有输入/输出模块一样，数字输入模块需要到远程外部终端面板的电缆接口。每个模块都采用机械键控，以防止在配置的机箱中安装不当。自检功能自检功能持续验证Tricon控制器检测电路转换的能力。此功能有两种版本：1）YPN107A YT204001-DM型号包括电路卡在开启自检功能，可验证检测从正常通电电路到关闭状态转换的能力。2） 型号3504E和3564包括电路卡在接通或卡在断开自检功能，该功能验证YPN107A YT204001-DM控制器检测从接通到断开或从断开到接通到相反状态的转换的能力。单个数字输入模块型号3564是单个数字输入模块，其针对低成本比可用性更重要的安全关键应用进行了优化。在单个模块上，只有确保安全操作所需的信号路径部分是三倍的。自检电路在不到500毫秒的时间内检测到非三重信号调节器内的所有卡滞接通和卡滞断故障情况。这是故障安全系统的一个强制性特征，该系统必须及时检测所有故障，YPN107A YT204001-DM并在检测到故障时将测量输入值强制设置为安全状态。
产品英文详情料:
Digital Input Modules include the hot-spare feature which allows online replacement of a faulty module. Like all I/O modules, Digital Input Modules require a cable interface to a remotely located YPN107A YT204001-DMexternal termination panel. Each module is mechanically keyed to prevent improper installation in a configured chassis. Self-Test Feature The Self-Test feature continuously verifies the ability of the Tricon controller to detect the transition of a circuit. This feature is available in two versions: 1) Models YPN107A YT204001-DM include a circuit stuck-On self-test feature that verifies the ability to detect transitions from a normally energized circuit to the Off state. 2) Models YPN107A YT204001-DM include a circuit stuck-On or stuck-Off self-test feature that verifies the ability of a Tricon controller to detect transitions to the opposite state—either from On to Off or from Off to On.Single Digital Input Module Model 3564 is a Single Digital Input Module, which is optimized for safety-critical applications where low cost is more important than maximum availability. On Single modules, only those portions of the signal path that are required to ensure safe operation are triplicated. Self-test circuitry detects all stuck-On and stuck-Off fault conditions within the non-triplicated signal conditioners in less than 500 milliseconds. This is a mandatory feature of a fail-safe system, which must detect all faults in a timely manner and upon detection of a fault, force the measured input value to the safe state.YPN107A YT204001-DM
