The Siemens 6ES7135-4MB01-0AB0 is an ET 200S analog output module with two configurable current outputs. Each output supports either 4 to 20 mA or ±20 mA ranges (deactivated state also selectable). Power comes from the backplane bus at 24 V DC, with a maximum current draw of 150 mA from load voltage L+ (unloaded). The module sits on a 15 mm wide base and occupies 4 bytes of address space, with a cycle time of 1.5 ms for all channels.
Mounts on an ET 200S terminal module; the 15 mm width allows high-density layouts along the DIN rail. The module supports isochronous mode for deterministic exchange with the controller. Response to CPU or master STOP is programmable: outputs can de-energize, hold last value, or substitute a safe value. Diagnostics are configurable for wire-break and group error, with the red SF LED indicating a group fault. Isolation between channels and the backplane bus is tested at 500 V DC.
