The 6ES7142-6BF50-0AB0 is an 8-channel digital output module from the SIMATIC ET 200eco PN family, designed for cabinet-free machine-mount installation. Each of its four M12 connectors carries two output channels through duplicate pin assignment, halving field cable count compared to single-assignment modules. The IP65/66/67 zinc die-cast housing withstands wet, dusty, and washdown environments.

How does duplicate M12 assignment simplify field wiring?

Each M12 socket carries two independent output channels:

By assigning two channels per connector, only four M12 cables are needed for eight outputs, reducing wiring cost and installation time in distributed architectures.

What load types suit the 0.5A output rating?

With 0.5A per channel, this module drives indicator lights, small solenoid valves, contactor coils, and signal lamps up to 5W. Switching frequency reaches 100Hz for resistive loads and 0.5Hz for inductive loads. For higher-current actuators such as large valves or motor contactors above 0.5A, use the 1.3A variant (6ES7142-6BF00-0AB0) instead.

Availability and lifecycle status

This product entered phase-out (PM400) on October 1, 2024. It remains orderable while stocks last. No direct successor has been announced. For new installations, consider the M12-L generation of ET 200eco PN for long-term availability and MultiFieldbus support.

Frequently Asked Questions

What is the difference between 6ES7142-6BF50-0AB0 and 6ES7142-6BF00-0AB0?

The sole difference is output current: 0.5A (6BF50) vs 1.3A (6BF00) per channel. Both share identical dimensions, connectors, PROFINET interface, and IP rating. The 0.5A variant dissipates less heat (3W vs 5.5W). Choose 6BF50 when 0.5A per channel is sufficient; choose 6BF00 for higher-current loads.

Can I daisy-chain multiple ET 200eco PN modules?

Yes. The integrated 2-port PROFINET switch on every ET 200eco PN module supports line topology without external switches, reducing infrastructure cost in distributed I/O architectures.
