Omron SMARTSLICE DATASHEET
SmartSlice
The smartest modular I/O system
OMRON's SmartSlice I/O system is compact, intelligent and
easy. When used with OMRON's CS1/CJ1 DeviceNet or
CompoNet master units, no configuration tool is required.
By using built-in functions such as pre-scaling, totalising,
differentiation and alarming in analog I/O units, PLC programming can be minimised. Preventive maintenance data
collected by all I/O units can be accessed using CX-Integrator or NS-series Smart Active Parts.
• Most compact in the market (84 mm high)
• Easy set-up, backup and restore functions
• Diagnostics and preventive maintenance data at I/O level
• Detachable terminal blocks allow hot-swapping without
re-wiring
• 3-wire I/O connection with 'push-in' technology, no screwdriver required
