Designed for the ControlLogix platform, the 1756-OX8I module provides eight isolated relay outputs, each capable of handling voltages from 10 to 265V AC or 5 to 150V DC. The isolation between channels enhances noise immunity and allows for independent operation of each output. The module requires a compatible removable terminal block (RTB), such as the 1756-TBCH or 1756-TBS6H, for field wiring connections. Its compact design facilitates easy integration into ControlLogix chassis, optimizing space within control panels.
