Product Overview
PFXGM4201TAD is a Pro-face GP4000M Series 3.5″ modular HMI. It offers DC analog input, TFT color LCD, and a resistive touch panel. This unit is ideal for compact control panels. It is now end of sales. A recommended substitute is PFXSTM6200WADE from the STM6000 Series.
Key replacement note: The PFXSTM6200WADE keeps the same panel cut-out size but has a different display resolution. The PFXST6200WADE (ST6000 Series) has a different cut-out and resolution. Always check the replacement book before ordering.
