A60MXT/A60MXR Isolated Multiplexer Module Replacement Bulletin

This technical bulletin recommends replacing the A60MXT and A60MXR isolated multiplexer modules with the newer A60MXTN and A60MXRN models due to environmental conservation requirements, specifically replacing the mercury relay with a Photo MOS relay. It details performance and function comparisons, transition guidelines including wiring modifications and jumper setting changes, and highlights advantages such as unrestricted relay life and improved vibration/shock resistance.
