Siemens 6ES7132-4BB31-0AB0 | SIMATIC ET 200S 2DO High Feature — 24V DC / 2A / Diagnostics / 15mm / 5-Pack

Part Number: 6ES7132-4BB31-0AB0

Manufacturer: Siemens AG (Germany)

Product Family: SIMATIC ET 200S 

Two High-Specification Outputs in 15mm — With Diagnostics

The 6ES7132-4BB31-0AB0 is a 2-channel digital output electronic module for Siemens' SIMATIC ET 200S distributed I/O system. At 2A per output channel, it drives loads that exceed the capability of the standard 0.5A output modules — solenoid valves with higher inrush currents, DC contactor coils, heavier duty actuators, and indicator loads with significant current draw. Two outputs in a 15mm-wide module keeps the ET 200S station compact even when higher-current outputs are needed.

The "High Feature" (HF) designation distinguishes this module from the Standard (ST) variant. The HF module's defining advantage is its diagnostics capability — the module monitors each output channel for short-circuit and open-circuit (wire break) conditions. When a short circuit occurs, the module detects the overcurrent, activates short-circuit protection, and reports the fault through the SF (group fault) LED on the module face and through the PROFIBUS DP diagnostic data to the S7 CPU. Open-circuit detection confirms that the output wiring is intact — a broken wire or disconnected load generates an open-circuit fault report before it causes a process problem.

The substitute value output function provides configurable failsafe behaviour — when the connection to the CPU is lost (PROFIBUS DP communication fault), the module can be configured to set its outputs to defined substitute values (force to 0, hold last state, or force to 1) rather than defaulting to all-off.

The 6ES7132-4BB31-0AB0 is sold in packs of 5. Each module is the same product; the 5-pack is the standard purchasing unit for this electronic module in the ET 200S range.

FAQ

Q1: Does the 6ES7132-4BB31-0AB0 require a specific terminal module for installation?

Yes. Each ET 200S electronic module requires a terminal module (TM) to provide the physical connection to the ET 200S power bus and the field wiring terminals. The appropriate terminal module for the 2DO HF module is confirmed from the ET 200S system manual — different terminal modules provide different wiring configurations. The electronic module itself does not include a terminal module; these are ordered separately.

Q2: What happens when a short circuit is detected on a 2DO HF output channel?

The module activates its short-circuit protection, limits the output current, and sets the SF LED on the module face. The fault is reported through the PROFIBUS DP diagnostic data to the S7 CPU, where it can trigger a programme alarm. If the substitute value function is configured, the affected output may be forced to a defined state. The output restarts automatically once the short circuit is cleared and the CPU acknowledges the fault.

Q3: Can the two output channels on the 6ES7132-4BB31-0AB0 be used for different load voltages?

Both output channels share the load voltage supplied to the module's supply terminal. Both channels operate from the same 24V DC load voltage — different voltage loads on different channels of the same module are not supported without external isolation. If different load voltages are required, use separate modules each connected to their respective supply.

Q4: What is the purpose of the substitute value function on a High Feature module?

The substitute value function defines what the output channels do when communication with the CPU is lost — for example, when the PROFIBUS DP bus fails or the CPU stops. Options typically include: force outputs to 0 (all off), hold the last commanded output state, or force outputs to 1 (all on). The substitute value is configured in STEP 7 or TIA Portal and stored in the ET 200S interface module. It protects the process from uncontrolled output behaviour during a communication fault.

Q5: How is the 6ES7132-4BB31-0AB0 ordered — one module or five?

The 6ES7132-4BB31-0AB0 is packed and sold in units of 5 electronic modules. One order of 6ES7132-4BB31-0AB0 supplies 5 identical 2DO HF modules. This is Siemens' standard packaging for ET 200S electronic modules — the pack quantity is stated in the product description and on the product label.
