Products Description
ELEMASTER IB3110551 Distributed I/O Module
ELEMASTER IB3110551 is a remote distributed I/O module manufactured by Elemaster. It acts as a field interface, collecting analog and digital signals from on-site sensors and transmitting data to the host control system via Modbus RTU serial bus.


This compact module integrates multi-channel I/O circuits with built-in surge and short-circuit protection. The front panel LED array indicates power status, channel activity and fault alarms. As aftermarket spare parts, it is widely used for maintenance, replacement and retrofit of factory automation and railway control systems.
