WIRELESS COEXISTENCEInduraNetp features coexistence frequency management (CFM), so the system can coexist with other wireless systems in the 2.4 GHz ISM band and give immunity to interference from other wireless services. InduraNETp can be added to a new or existing I/O block without changing hardware. A maximum of 64 operational and safety input/output modules, each with two or four I/O, can be installed in any order alongside a single PSSuniversal head module.
