Siemens 6ES7137-6BD00-0BA0 ET 200SP CM 4xIO-Link ST 4-Port Communication Module

The Siemens 6ES7137-6BD00-0BA0 is a SIMATIC ET 200SP CM 4xIO-Link ST communication module, an IO-Link master with 4 simultaneously controllable ports supporting IO-Link protocol 1.0 and 1.1. It runs on a 24 V DC backplane supply, draws 45 mA without load, and provides a 700 mA rated output current per channel from its 24 V encoder supply (2.1 A max. short-circuit protected).

Technical Specifications

Selection Notes

The 4 simultaneously controllable ports (not multiplexed) let this module poll all connected IO-Link sensors and actuators on every ET 200SP cycle without a scan-time penalty, so it fits applications that need real-time feedback from more than one IO-Link device per station. Support for both IO-Link protocol 1.0 and 1.1 means it accepts older field devices as well as current ones on the same module. The 20 m unshielded cable length limit (also applying to shielded cable per the datasheet) should be checked against actual sensor-to-module cable runs before specifying it on a large machine.

Applications

Connects IO-Link sensors and actuators - proximity switches, pressure transmitters, valve terminals - into a SIMATIC ET 200SP station, giving parameter access and diagnostics per port instead of simple binary I/O.
