SIEMENS 6AV6640-0AA00-0AX0 TD 400C Text Display | S7-200 HMI Panel

SIEMENS 6AV6640-0AA00-0AX0 TD 400C Text Display – SIMATIC S7-200 Series

When a production line loses its operator interface, engineers are left blind — unable to monitor process variables, acknowledge alarms, or adjust setpoints without halting operations. In time-critical industrial environments, even minutes of downtime translate directly into lost output and costly maintenance escalations. The SIEMENS TD 400C Text Display (6AV6640-0AA00-0AX0) eliminates this vulnerability by providing a robust, dedicated HMI solution engineered specifically for SIMATIC S7-200 PLC systems.

Within the SIMATIC S7-200 HMI ecosystem, the TD 400C occupies the entry-level yet highly capable tier — offering a cost-effective, space-efficient display solution for machines and panels where a full-color touchscreen is unnecessary but reliable text-based monitoring is essential. Trusted by OEMs and system integrators across manufacturing, water treatment, HVAC, and packaging industries worldwide, the 6AV6640-0AA00-0AX0 has established itself as a dependable workhorse in global industrial automation deployments.
