Frequently Asked Questions

Does this module support redundancy?
Yes. PW482-50 modules are typically installed in pairs. The system balances the load, and if one module fails, the other takes over without process interruption.

Is the -20°C to +70°C rating applicable to all PW482 versions?
No. Only temperature-specific variants like the PW482-50 are rated for this range. Standard PW482 modules are usually rated for 0°C to 50°C.
