Product Description
Model MGate 5101‑PBM‑MN is an industrial protocol conversion gateway manufactured by MOXA. It is a 1‑port PROFIBUS‑DP V1 Master to Modbus‑TCP gatewayMoxa. Operating as PROFIBUS DP master, it connects PROFIBUS‑DP slave devices such as servo drives, instruments and PLCs, enabling bidirectional data exchange with Modbus‑TCP client/server hosts. Rugged metal housing for DIN‑rail mounting. Dual redundant DC power inputs and relay alarm output are provided. PROFIBUS serial port with built‑in 2 kV optical isolation; Ethernet port with 1.5 kV magnetic isolation. Configuration via MGate Manager utility or built‑in web console. Auto‑scan for PROFIBUS slaves, traffic diagnostic and fail‑safe functions are integrated. Standard model operates 0‑60℃; the‑T variant supports wide temperature‑40~+75℃. Suitable for factory automation, power, oil‑gas process automation, new system integration and legacy equipment spare‑part replacementMoxa Inc..
