EXSYS EX-6011 Ethernet to 8-Channel Digital I/O Adapter, Modbus TCP, Opto-Isolated, DIN-Rail

Industrial Ethernet digital I/O adapter with 8 opto-isolated inputs and 8 opto-isolated NPN open collector outputs, delivering reliable remote monitoring and control over 10/100 Mbps Ethernet. The EX-6011 supports Modbus TCP, TCP/IP, UDP, HTTP, DHCP, SNMP, SMTP, and NTP protocols, making it a versatile solution for factory automation, building management, and SCADA systems.

Advantages

Optical isolation of 2.5 kV protects your control system from voltage spikes and ground loops. The wide power input range of +9 to +48 V DC and built-in hardware watchdog ensure stable operation in demanding industrial environments. Configuration is simple via a web interface or Windows utility, and the rugged metal housing mounts easily on a 35 mm DIN rail or wall.
