Remote I/O for safety

Jan. 30, 2023

LB Remote I/O system for Zone 2/Div. 2 connects sensors and actuators to the DCS using one standardized fieldbus connection, such as Profibus and Modbus. A wide range of single- and multi-channel I/O modules is available, ensuring that engineering is easy and adaptable to the needs of any plant concept. With up to eight channels per I/O module, LB’s modules are plugged into a backplane, while the energy-saving power management system and low power dissipation allow maximum packing density. LB I/O modules can be inserted into any slot, enabling a customized mix of I/O signals. In addition, the relay outputs are hot-swappable, which allows quick and easy module replacement without time-consuming system shutdowns.
