Siemens 6ES7194-4AJ00-0AA0 SIMATIC ET 200pro CM IM PN 2x M12 2x 7/8 Inch 8A Remote I/O Accessory

The Siemens 6ES7194-4AJ00-0AA0 is a PROFINET connection module for the SIMATIC ET 200pro M154-4PN High Feature interface module, providing two M12 and two 7/8 in. power ports. It accepts up to 8 A on both the 1L+ and 2L+ supply rails and internally transfers up to 8 A on 2L+ and 5 A on 1L+. The unit measures 90 x 130 x 51 mm and weighs 540 g.

Technical Specifications

Selection Notes

This CM version routes both the 1L+ sensor supply and 2L+ actuator load voltage through separate M12 and 7/8 in. ports, so it supports stations that need the standard ET 200pro power split rather than a single combined feed. The 8 A per-rail limit sets the ceiling on how many downstream I/O modules the M154-4PN interface segment can carry before an additional power module is needed.

Applications

Mounts beneath the SIMATIC ET 200pro M154-4PN High Feature PROFINET interface module to bring in and distribute 1L+/2L+ power for the I/O modules in that station, typical in machine-mounted distributed I/O on production lines.
