Product details

The Siemens 6ES7924-0BE20-0BA0 is a connection module for digital input signals in SIMATIC S7-300 systems. It has 20 screw-type terminals, rated at 50 V and 1 A.

Mounting and wiring reality

The terminals sit on top, single level, accepting 0.5 to 2.5 mm² stranded wire with a 3.5 mm screwdriver blade. Maximum cable run between this module and the front connector is 30 m, so keep the remote I/O within that span. No shield connection or PE terminal here — this is a pass-through block, not a grounding junction.

Environmental tolerance

Operates from 0 to 60 °C, stores from -40 to +70 °C.

Frequently asked questions

What is the closest functional second-source or alternative?

The 6ES7522-5HF00-0AB0 is a different class of module (digital output, not input connection) and will not drop into the same panel position without rewiring. The 6ES7924-0BE20-0BA0 is purpose-built for S7-300/1500 input signal connection; there is no direct pin-compatible substitute from the peer list. Source this exact order code for a drop-in fit.

What are the key electrical ratings?

Rated voltage 50 V, rated current 1 A. It is designed for digital input signal switching, not power distribution. The switching contact is a single-pole normally-open type.

What wire sizes and termination type does it accept?

Screw-type terminals accept 0.5 to 2.5 mm² stranded wire. A 3.5 mm screwdriver blade is specified for termination. Up to two wires per connection are allowed if the combined cross-section fits within a single ferrule.
