SmartSlice GRT1 remote I/O terminals have a CompoNet interface unit and ac input modules. CompoNet networks distribute sensor and actuator I/O status. The ac input modules are designed to reduce space and incorporate 110 Vac or 240 Vac inputs by offering four inputs. SmartSlice uses building-block style I/O terminals that allow connection of up to 64 remote I/O units to expand an I/O system. Pin terminal blocks are designed to enable screwless wiring.
