Siemens 6AV3627-1JK00-0AX0 is the OP27 operator panel for SIMATIC S5 systems, delivering a 5.7-inch STN monochrome LCD with 240 × 320 pixel resolution and eight gray levels. It uses a fixed membrane keyboard with 24 function keys (18 with LEDs) and a non-touch, vertical-mount design for rugged industrial panels. The display is powered from 18 V DC and draws about 0.3 A, with backlighting rated for an MTBF of roughly 50,000 hours. This HMI provides a compact, reliable operator interface suited to process and machine-control applications in older Siemens installations.
