- Description
The Siemens 6ES7138-7EC00-0AA0 is a SIMATIC ET 200iSP power supply module rated 120/230 V AC, feeding the backplane and power bus of an intrinsically safe distributed I/O station with redundancy capability and a 20 ms buffering time. It accepts 85-264 V AC at 47-63 Hz, carries an IP30 rating, and is certified Ex db eb [ib] IIC T4 Gb for Zone 1 gas areas.

Selection Notes
Redundancy capability lets two of these modules feed one ET 200iSP station in parallel, so pick this over a non-redundant supply when the power bus must stay live through a single-supply fault or a maintenance swap. The 20 ms buffering across the backplane bus, powerbus, and IM 152 CPU means AC interruptions shorter than 20 ms do not reset the station. Its 85-264 V AC input range covers both 120 V and 230 V distribution from one catalog number, so no separate model is needed per mains voltage.
