Product Description
The Honeywell 2MLQ-RY2B is a 16-point digital relay output module belonging to the MasterLogic-200 PLC system. Designed for robust industrial control, it provides high-reliability relay outputs with enhanced protection through integrated surge absorbers (varistor and C.R. absorber). It supports switching for both AC and DC loads and is suitable for applications requiring electrical isolation and noise resistance.
