Siemens 6AV3525-1EA01-0AX0 OP25 Operator Panel is a SIMATIC HMI device featuring a monochrome LC display with pixel graphics for local operator interaction. It operates from 24 V DC and is shipped without a direct keypad, designed to pair with external input devices and PLCs for machine- or line-level control. The OP25 provides four integrated interfaces (2× TTY/V.24, X.27/TTY, MPI/PPI), enabling flexible serial and fieldbus connectivity to Siemens controllers and automation networks. This panel is intended for industrial environments where operators must view critical process data and issue commands at the point of use, serving as a compact, cost-effective operator interface within the SIMATIC HMI family.
