Siemens AG 6ES5760-0HA11 Connector Terminator

Siemens 6ES5760-0HA11 Connector Terminator is a terminating resistor connector designed for the IM314 CC interface module in SIMATIC S5 systems. It provides the end-of-line termination that helps prevent signal reflections on the CC bus and maintain reliable communications for the IM314 CC interface. Manufactured by Siemens AG, this part appears in distributor catalogs as the 6ES5760-0HA11 variant of the terminator for IM314 CC interface modules, with Siemens documentation also noting a related terminator model such as 6ES5760-1AA11 for similar peripheral configurations. In practice, the 6ES5760-0HA11 is used in older SIMATIC S5 deployments that rely on the IM314 CC interface module, such as installations referencing IM314 CC and S5-135/55 configurations. Availability can vary by region and catalog; several suppliers list 6ES5760-0HA11 as discontinued by the manufacturer, while others offer used or surplus stock, reflecting its status as an older, legacy component. This connector terminator is a dedicated plug‑in termination element rather than a general resistor network, intended specifically for IM314 CC interface modules to ensure correct line termination and stable bus operation in legacy Siemens automation architectures.
