Product Description:

The industrial controller RC4-5/30 belongs to the BODAS Controllers series from Bosch Rexroth Indramat. Designed for off-highway and mobile automation, the unit supervises hydraulic valves, engine parameters, and auxiliary functions by processing sensor inputs and issuing proportional or switched outputs. Its rugged housing and automotive-grade electronics let OEMs place the controller close to actuators, reducing wiring length and simplifying machine layouts.

The mechanical interface is defined for installation repeatability. Wiring harnesses may be routed up to 150 mm from the enclosure without jeopardizing strain-relief requirements, which helps preserve cable support near moving equipment. The mounting surface gap must remain below 10 mm to prevent case distortion when fastened. Direct tightening without a washer is limited to 2.5 Nm, while adding a plain washer allows screws to reach 3.0 Nm so clamping force can be increased when higher vibration levels are expected.

Environmental storage limits complement the mounting rules. Components stay within specification at a mean relative humidity of 60 %, and screw heads no smaller than 7 mm help maintain consistent seating on the integrated brass inserts. For production logistics, the electronics tolerate warehouse holding periods of up to 100 h outside sealed packaging, provided surfaces remain flat within 0.5 mm to avoid internal stress on the PCB. When these conditions are met, the controller maintains calibration over the five-year inspection interval stated by Bosch Rexroth.

Wake Industrial stocks the controller. Same-day shipping is available, and purchases include a 1-year warranty. The chat tool on the website answers fault-code questions.
