UAC383AE01 HIEE300890R0001 is the standard digital signal acquisition board for UNITROL excitation cabinets, equipped with 16 independent optocoupler isolated digital input channels, evenly divided into two groups of 8 channels each with separate power supply monitoring circuits. It collects field binary signals including generator circuit breaker auxiliary contacts, excitation switch status, turbine trip command, PT/CT fault interlock and synchronizer enable feedback. Optical isolation completely isolates high-voltage secondary circuit interference to avoid control board damage caused by ground loop surge. Real-time voltage monitoring of each group can instantly report wire break and power loss faults to the main processor via VME backplane bus. Full conformal coated PCB with strong anti-vibration and anti-electromagnetic interference performance, it is essential replacement spare part for thermal, hydro and gas power plant generator excitation cabinets.UAC383AE01 HIEE300890R0001 是 UNITROL 励磁控制柜标配数字信号采集板，搭载 16 路独立光耦隔离数字输入通道，平均分为两组 8 通道，每组配套独立供电监测回路。采集发电机断路器辅助触点、励磁开关状态、汽机跳机指令、PT/CT 故障联锁、同期使能反馈等现场开关量信号；光耦隔离彻底隔绝高压二次回路干扰，杜绝地环路浪涌损坏控制板。每组回路实时电压监测，可通过 VME 背板总线向主控即时上报断线、失电故障；全板三防涂层 PCB，抗震、抗电磁干扰性能优异，是火电、水电、燃气电厂发电机励磁柜必备替换备件。
