Wireless I/O

The OptoGSM I/O rack accepts industry standard, G4-footprint, plug-in digital I/O modules and offers three built-in analog inputs. Combined with a Nokia 30 or 31 GSM connectivity terminal, the I/O rack transmits machine or environmental data over any Global System for Mobile Communications (GSM) network. The resulting system provides machine connections, mobile communications, and carrier services to communicate with systems and equipment.
