Functional Capabilities

The 6ES5380-8MA11 operates independently of the PLC’s internal timers. It provides hardware-based timing that is essential for certain control tasks . When a control signal reaches the input, the timing sequence begins immediately. After the preset time elapses, the module activates the corresponding output. The output remains active until the control signal stops . This module features a setting error of ±5% and reproducibility of ±2% . Its response time is approximately 20 ms .

Application Scenarios

This module implements time delays and intervals in automation processes without altering the PLC program . Its outputs connect directly to PLC digital inputs for monitoring purposes. The compact design suits space-constrained control cabinets. Additionally, galvanic isolation between inputs and outputs ensures reliable operation in noisy environments . Users can rely on this legacy module to maintain existing S5-based automation systems.
