Survives the nacelle extremes
The 6ED1052-1MD08-0BA1: Eight digital inputs include four that double as 0–10 V analog inputs, letting you read a pressure transmitter or wind speed sensor without an expensive expansion card. Four relay outputs handle 3 A inductive or 10 A resistive loads; the relays are rated for the surge a small contactor coil or brake resistor can throw. 400 function blocks give enough logic for a pitch control governor, a tower vibration trigger, or a hydraulic brake sequence. The integrated web server and data logger mean you can pull trending data from a remote SCADA system without opening the cabinet door.
Mounts 4SU, not 6SU
Replaces the peer model (107 mm wide, 55°C max) with a narrower 71.5 mm (4 SU) on 35 mm DIN rail. Same 10.8–28.8 V DC supply range and relay ratings; depth increases to 60 mm.
Ready for world-wide approval stacks
Active and CE, UL, CSA, FM, and Marine approved. EN55011 Class B emission limits for residential EMC.
Sourcing for a current-design BOM
As a current-production part, the 6ED1052-1MD08-0BA1 is quoted to order through our normal Siemens supply channel. No last-time-buy deadlines to chase, and the 480-hour power reserve means it will hold its real-time clock and program memory through a weekend panel power-down.
