Product details

What this module is

The Siemens 6ES7141-1BF40-0XB0 is the EM141 extended module for the ET 200X distributed I/O system, delivering 8 digital inputs rated at 24 V DC with M12 5-pole connectors. It accepts signal '1' from 13 to 30 V and signal '0' from -3 to +5 V, and the input delay is parameterizable to 0.5, 3, 15, or 20 ms via the backplane bus. Each input supports per-channel diagnostics: wire-break and short-circuit detection, along with a parameterizable hardware interrupt and diagnostic alarm. The module draws 30 mA from the 5 V DC backplane bus and dissipates 1.5 W.

Connection and integration notes

Permissible quiescent current is 1.5 mA; inputs are not potential-separated from the backplane. Maximum unshielded cable length is 30 m.

Frequently asked questions

What is the depth and width of this module?

Depth is 55 mm. Overall width is 87 mm, and the module width specifically is 60 mm.

Can the 6ES7148-4FC00-0AB0 serve as a direct drop-in replacement?

No. That ET 200SP module has different dimensions (90 x 130 x 65 mm versus 87 x 180 x 55 mm), uses a different backplane connection, and includes four additional outputs. A system redesign would be required.
