YXU169H 3ASD273001B5继电器输出模块继电器输出（RO）模块是非三重模块，用于与高侧固态输出开关（如信号器面板）不兼容的非关键点。继电器输出模块在三个通道中的每个通道上接收来自主处理器的输出信号。然后对这三组信号进行表决，表决后的数据用于驱动32个单独的继电器。每个输出都有一个环回电路，该电路独立于负载的存在来验证每个继电器开关的操作。YXU169H 3ASD273001B5正在进行的诊断测试RO模块的运行状态，YXU169H 3ASD273001B5模块不用于关键点或现场负载切换。监控数字输出模块监控数字输出（SDO）模块提供电压和电流环回，允许通电跳闸和断电跳闸条件下的完整故障覆盖。YXU169H 3ASD273001B5模块监控现场电路，以便可以检测到这些现场故障：断电或保险丝熔断、负载开路或缺失、导致负载错误通电的现场短路，以及断电状态下的短路负载。现场负载的任何损失均由模块通知。115 VAC数字输出模块此图为YXU169H 3ASD273001B5型TMR数字输出模块的简化示意图。

Relay Output Modules Relay Output (RO) Modules are non-triplicated modules for use on non-critical points which are not compatible with high-side solid-state output switches, such as annunciator panels. YXU169H 3ASD273001B5Relay Output Modules receive output signals from the Main Processors on each of three channels. The three sets of signals are then voted, and the voted data is used to drive the 32 individual relays. Each output has a loopback circuit which verifies the operation of each relay switch independently of the presence of a load. Ongoing diagnostics test the operational status of theYXU169H 3ASD273001B5Module, which is not intended for use on critical points or switching of field loads. Supervised Digital Output Modules Supervised Digital Output (SDO) Modules provide both voltage and current loopback, allowing complete fault coverage for both energized-to-trip and de-energized-to-trip conditions. YXU169H 3ASD273001B5modules supervise the field circuit so these field faults can be detected: loss of power or blown fuse, open or missing load, field short resulting in the load being energized in error, and shorted load in the de-energized state. Any loss of field load is annunciated by the module.115 VAC Digital Output Modules This figure is a simplified schematic for models YXU169H 3ASD273001B5 which are TMR Digital Output Modules.
