Distributed I/O block for ET 200B stations
The Siemens 6ES7133-0BN00-0XB0 is an ET 200B distributed I/O block that packs 24 digital inputs and 8 digital outputs into a single compact module, with a 3 ms output response time. It is classified under PLC expansion modules and sits within the PLCs & HMIs category, meaning it is designed to snap onto a DIN rail in a control cabinet and communicate over the ET 200 backplane.
I/O count and response constraints
With 24 inputs and 8 outputs, this block handles a mixed-signal footprint that suits medium-density machine sections — think a small conveyor zone or a packaging station with a dozen sensors and a handful of actuators. The 3 ms output response time sets the minimum pulse width the module can deliver; a downstream PLC scan must account for this when timing a fast solenoid or a clamp cylinder.
