The 3UF7020-1AB01-0: The 22.5 mm width of this control unit matches the standard single-module DIN-rail pitch, so it occupies one slot in a SIMOCODE pro S lineup alongside the current/voltage sensing modules and the bus interface. The height is 100 mm and the depth is 124.5 mm, with a required top clearance of 40 mm and bottom clearance of 40 mm for wiring access and heat dissipation. Mounting is by screw or snap-on onto the DIN rail, both methods listed as supported.
What the ratings decide in the BOM
This is the control unit of the SIMOCODE pro S system — it handles the logic, the 4 digital inputs, and the relay output for motor starting and protection. The 24 V rated supply powers the unit and the connected sensors. The 4 digital inputs accept 24 V signals from pushbuttons, selector switches, or PLC outputs. The unit also provides current detection for the motor circuit, feeding back the actual load current to the protection algorithms.
