产品详细资料
SRXM模块与行业标准ST光纤连接器兼容。指定的坏情况下的分贝光功率预算包括由于SRXM发射机和接收机处的光纤连接器造成的损耗,以及2分贝裕度/老化损耗。在计算大安装电缆长度时,应考虑光纤电缆拼接或接线盒耦合引起的额外损失。所有模拟输入模块都有三个独立的输入通道。每个输入通道接收来自每个点的可变电压信号,将其转换为数字值,并根据需要将这些值传输到三个主处理器。为了确保每次扫描的数据正确,使用中值选择算法选择一个值。以防止一个通道上的单个故障影响另一个通道的方式执行每个输入点的感测。3700A、3703E、3704E、3720和3721型模拟输入模块提供6%的超量程测量能力。3703E提供开放输入检测,可在TriStation 1131中配置为或低档。如果开路输入(<0 VDC)超出范围下限,主处理器将接收整数值–32767。如果开路输入(>5 VDC或10 VDC)超出范围上限,主处理器将接收整数值+32767。
SRXM Modules are compatible with industry-standard ST fiber-optic connectors. The specified worst-case optical power budget of decibels includes losses due to the fiber-optic connectors at the SRXM transmitter and receiver, and 2 decibels margin/aging loss. Additional losses incurred by fiber-optic cable splices or junction-box couplings should be considered when calculating the maximum installed cable length.All Analog Input Modules have three independent input channels. Each input channel receives variable voltage signals from each point, converts them to digital values, and transmits the values to the three Main Processors on demand. To ensure correct data for every scan, one value is selected using a mid-value selection algorithm. Sensing of each input point is performed in a manner that prevents a single failure on one channel from affecting another channel. The Model 3700A, 3703E, 3704E, 3720, and 3721 Analog Input Modules provide a six percent over-range measurement capability. The 3703E provides open-input detection, which can be configured as upscale or downscale in TriStation 1131. If an open input (< 0 VDC) goes out of range downscale, the Main Processors receive the integer value –32,767. If an open input (> 5 VDC or 10 VDC) goes out of range upscale, the Main Processors receive the integer value +32,767.
