Features:
- Each electronic module accepts two High Feature 24 V DC input channels.
- Configurable delays and rising-edge interrupts shape the response to field transitions.
- Channel LEDs and encoder-supply diagnostics separate input states from wiring faults.
Siemens 6ES7131-4BB01-0AB0 is the five-piece package code for the two-channel ET 200S High Feature input module.
A compatible terminal module presents the sensor power, ground, input, and optional AUX1 connections to each electronic module.
The input circuits feed the ET 200S backplane through an isolated interface while sharing their channel-side reference within the module.
The Siemens 6ES7131-4BB01-0AB0 SIMATIC ET 200S 2DI High Feature Digital Input Module 5-Pack may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Selecting the field-connection base for each module
- Spring Terminals: TM-E15C variants provide spring-clamp field connections in the listed conductor arrangements.
- Screw Terminals: TM-E15S variants provide the corresponding screw-type terminal layouts.
- Fast Connect: TM-E15N variants support the documented Fast Connect field-wiring option.
- AUX1 Access: The selected terminal-module layout determines whether the optional AUX1 terminals are present.
Following a powered field signal into ET 200S
- Sensor Feed: L+ supplies the connected switch or proximity sensor from the module-side 24 V path.
- Signal Return: DI0 or DI1 receives the field state while M completes the channel reference.
- Input Electronics: The two channel circuits convert the field states before the data enters the backplane.
- Backplane Boundary: Electrical isolation separates the field-side input circuits from the ET 200S bus.
Controlling when an input transition reaches the controller
- Delay Choice: One module-wide delay applies to both rising and falling input transitions.
- Edge Trigger: Rising-edge process interrupts can be enabled individually for channel 0 and channel 1.
- Interface Requirement: Interrupt parameterization requires the documented High Feature interface module or CPU.
- Synchronous Cycle: Isochronous support aligns input acquisition with the distributed-I/O cycle.
Separating channel state from module diagnostics
- Green LEDs: One green indicator reports the active state of each digital input.
- Red SF LED: The group-fault indicator turns on for a pending diagnostic or incorrect parameter assignment.
- Supply Fault: A short circuit in the encoder supply is reported through the module diagnostic path.
- Shared Message: The encoder-supply fault is reported on channel 0 and applies to the complete module.
