The 6ES7138-4CB10-0AB0 is a SIMATIC DP power module (PM-E) for the ET200S distributed I/O system. It provides a fused, regulated supply voltage for the electronics and field devices, accepting both DC (24-56.7 V) and AC (24-48 V / 120 V / 230 V) inputs. Diagnostic feedback includes group error (SF red), fuse blown (FSG green), and load-voltage monitoring (PWR green), configurable as enable/disable. The internal fuse is a 5×20 mm, 250 V, 10 A quick-response type, replaceable in the field without removing the module.
Sourcing and compliance posture
The module is isolation-tested at 1 500 V AC between load voltage and backplane bus, and carries reverse polarity protection and overvoltage protection – factors that support qualification documentation for plant-change control reviews.
Physical integration into ET200S rack
Width of 15 mm matches the standard ET200S electronic module form factor; depth 52 mm, height 81 mm. The module snaps onto the DIN rail mount of the ET200S interface module and connects via the backplane bus. Maximum power loss is 5 W.
