Expert Tips: Relay Load Balancing
When installing the FX3SA-20MR-CM, be mindful of the total current through the COM terminals. While each point can handle 2A, the common terminal should not exceed 8A. For high-cycle applications (switching more than once every few seconds), we recommend using interposing relays to save the internal PLC contacts. Sourcing your FX3SA-20MR-CM from Atlantechdrives ensures you receive a unit with low-resistance relay contacts, minimizing heat buildup inside the compact housing.
Maintenance and Hardware Protection
The FX3SA-20MR-CM is designed for a long, maintenance-free life. It uses flash memory for program retention, so there is no battery to replace. Periodic maintenance should focus on terminal screw tightness to prevent arcing due to industrial vibration. Sourcing from Atlantechdrives guarantees the hardware quality required for 24/7 service in decentralized automation cells.
