The Eaton MTL5582B is a professional industrial multiplexer designed for hazardous area process control applications. It supports up to sixteen mixed signal inputs from thermocouples RTDs millivolt sources and potentiometers for centralized signal collection. Featuring intrinsic safety design compliant with international safety standards it operates steadily in Zone 0 hazardous environments. It transmits both data and power via a single twisted pair cable to simplify on site wiring and reduce installation costs. With reliable signal conversion and strong anti interference performance it ensures accurate long distance data transmission and serves as a core signal multiplexing component for petrochemical and industrial automation systems.
Communication & Typical Applications
– Main protocol: DNP3.0 over Ethernet (SCADA remote monitoring, pipeline / wellhead / pumping station / distribution network automation)
– Suitable for: oil and gas wellheads, long-distance pipelines, gas metering stations, water resources management, and solar-powered RTU field sites
Key points
– Model: MTL831C (fixed terminals) | Variant MTL831C-PS = plug-in terminals version**
– Channels: **Up to 16 mixed inputs**
✔ Thermocouple TC / mV signal ✔ 2/3/4-wire RTD thermoresistance ✔ Potentiometer (can be mixed) Eaton
– Explosion-proof: **Intrinsic safety Ex ia, can be directly installed in Zone 0** (ATEX / IECEx certified) Eaton
– Transmission: Single shielded twisted pair Data Highway, signal + power on the same cable, maximum distance up to 2 km Eaton
– Networking: **One MTL838C receiver can connect up to 2 MTL831C → Total 32 points, output Modbus RTU (MTL838C-MBT is Modbus TCP)
