MTL 8604-FT-FU是MTL 8000 I/O系统配套带熔丝保护现场终端模块，8通道设计，专门搭配8103-AI-TX模拟量输入卡，为两线制4-20mA变送器提供回路供电与接线端子。

MTL 8604-FT-FU is fused field terminal for MTL 8000 I/O system. It has 8 channels and works with 8103-AI-TX analog input card, supplying power and termination for 2-wire 4-20mA transmitters.

每通道内置独立熔断器，回路短路、过流时单独熔断隔离故障，防止现场故障冲击背板与I/O卡件；标准DIN导轨卡装，紧凑布局适配控制柜，支持危险区域本安/非本安回路布线，是石化化工DCS柜常用备件。

Each channel is fitted with individual fuse to isolate short circuit and over-current fault, protecting I/O backplane and cards from field surge. Standard DIN rail mount for compact cabinet layout, compatible with hazardous area wiring for DCS systems in petrochemical plants.
