6ES7193-4CA30-0AA0 Product Overview
The Siemens 6ES7193-4CA30-0AA0, also known as the SIMATIC DP Terminal Module TM-E15C24-A1, is a compact terminal module designed specifically for the ET 200S distributed I/O system. It serves as the physical connection bridge between electronic modules (such as digital/analog I/O) and field devices, providing a standardized, high-reliability wiring interface for 15mm wide electronic modules.
This terminal module features advanced spring-loaded connection technology, enabling tool-free wiring that significantly boosts on-site installation and maintenance efficiency. An integrated AUX bus (AUX1) allows for the application of any desired potential up to 230V AC, serving as a protective conductor or distributing auxiliary voltage. With support for 2x4 terminal connections and continuous AUX1, it ensures distributed supply of auxiliary voltage within the system.
As a core accessory of the ET 200S system, this module supports "Hot Swapping," allowing module replacement during bus operation, dramatically improving the availability and productivity of industrial automation lines. It is typically sold in packs of 5 and is RoHS compliant.

FAQ:
What is the Siemens TM‑E15C24‑A1 (6ES7193‑4CA30‑0AA0) terminal module?
It is a 15 mm wide screw‑type terminal module for the SIMATIC ET 200S distributed I/O system. It serves as the physical base for two‑channel electronic I/O modules, providing the screw terminals for field wiring and an internal bus connection to the ET 200S backplane. The “C” designation indicates screw‑type terminals, and “24” means it includes 24 V auxiliary terminals for supplying sensors and actuators.
How does the TM‑E15C24‑A1 differ from the TM‑E15S24‑A1?
The TM‑E15C24‑A1 uses screw‑type terminals (C = Cage Clamp / Screw) for tool‑based tightening, while the TM‑E15S24‑A1 (S = Spring) uses push‑in spring‑loaded terminals that are pressed by hand. Electrically and mechanically they are identical—same 15 mm width, auxiliary 24 V supply, and slot compatibility. The choice depends on whether you prefer screw terminals or tool‑free spring connections in your panel wiring standard.
Which ET 200S I/O modules use this terminal module?
All 15 mm wide, two‑channel electronic modules that require external power for sensors/actuators are compatible. Typical examples include digital input modules (2×DI 24 V DC), digital output modules (2×DO 24 V DC, up to 2 A), digital input/output combination modules, and certain analog input/output modules. The specific module that uses this terminal is always listed in the ET 200S device manual or the module’s datasheet.
How do I wire the screw terminals, and what is the maximum wire gauge?
The screw terminals accept solid, stranded, and ferruled conductors with a cross‑section of 0.14 mm² to 1.5 mm² (AWG 26‑16). To wire, strip 6 mm of insulation, insert the conductor, and tighten the screw with a 3 mm flat‑head screwdriver to a torque of 0.5‑0.6 Nm. Each terminal point has a corresponding label on the module face for channel assignment.
What is the purpose of the 24 V auxiliary terminals (A1, A2)?
The A1 (24 V) and A2 (0 V) auxiliary terminals provide a convenient supply connection for the sensors and actuators that are wired through the I/O module. By connecting the field power once at the terminal module, all channels on the plugged‑in I/O module receive their supply without requiring separate terminal strips. This reduces wiring effort and keeps the panel tidy.
Can I use this terminal module with 2‑wire and 3‑wire sensors?
Yes. For 2‑wire sensors, connect the sensor’s “+” and “−” wires directly to the input terminals; the module supplies power through the AUX rail. For 3‑wire sensors (e.g., PNP NO), connect the brown wire to AUX +, the blue wire to AUX −, and the black signal wire to the input channel terminal. The screw‑terminal design provides secure clamping for each wire.
Is the TM‑E15C24‑A1 compatible with all ET 200S interface modules and power modules?
Yes, as a terminal module it fits onto any standard ET 200S backplane rack and can be installed next to any interface module (IM) or power module (PM). The electronic module is plugged onto the terminal module after the terminal module is mounted on the rail. The combination is mechanically guided and error‑proofed by coding pins, so a module that requires 24 V AUX will only fit onto a terminal module that provides the AUX terminals.
What is the width of this module, and how many can I fit on a 1‑meter ET 200S rack?
The TM‑E15C24‑A1 is 15 mm wide. On a standard 1‑meter (1000 mm) ET 200S mounting rail, you can install up to 66 of these terminal modules. The exact number depends on the space taken by the interface module, power modules, and any wider terminal modules (e.g., 30 mm, 45 mm) in the same station.
Does this terminal module provide any diagnostic features or LEDs?
No. The terminal module itself is a passive carrier and does not contain electronics or LEDs. Any status or diagnostic indication comes from the I/O electronic module that is plugged onto it. The AUX terminals also have no internal fuse; you must protect the field supply externally if required.
What are the most common use cases for the TM‑E15C24‑A1 in industrial automation?
It is widely used in machine‑building, conveyor systems, and process skids where ET 200S is the distributed I/O of choice. Its compact 15 mm width, screw‑terminal reliability, and integrated 24 V AUX supply make it ideal for wiring discrete sensors, solenoid valves, contactors, and small actuators directly onto the terminal module while keeping the control panel neat and serviceable.
