ADVANTECH BB-MESR921

Industrial Modbus Ethernet/Serial Gateway – DB9/TB, (2) RJ45

BB-MESR921 Modbus Gateway bridges devices on Modbus serial networks (RS-232, RS-422 or RS-485) with those on Modbus TCP networks, allowing seamless integration. Serial port/s can be accessed over a LAN or WAN using Direct IP Mode connections. Supporting up to 16 masters and 32 slaves, the gateway features auto-detecting 10/100 copper. Serial data rates up to 230 kbps ensure maximum network flexibility. The Ethernet Modbus/Serial Gateway is built for industrial environments, featuring a slim IP30 DIN rail mount case. It operates from a range of DC power supply voltages and has pluggable terminal block connectors. An external power supply is required (not included, sold separately).
