    The control contacts for parallel operation facilitate uniform current distribution between two devices connected in parallel. A non-isolated connection is established from the leading SITOP PSU8400 (OUT) to an additional SITOP PSU8400 (IN) using a wire connection. This synchronizes the two connected power supplies in operation. This uniformly distributes the currents of the synchronized devices for a constant output voltage independent of the load.

    PCT In this case, a distinction is made between cyclic data (process data, value status) and acyclic data (device data, events). SITOP PSU8400 supports cyclic communication every 4 ms. However, the cycle time that is actually used depends strongly on the IO-Link master being used. This is then appropriately defined depending on the data transmission rate that is supported.
