Product Description
- The SMC SI unit EX250-SAS3 is used in industrial automation to connect valve islands and decentralised inputs and outputs to AS-i networks.
- It is suitable for use in machinery and production systems with AS-i communication.
- The module is used to transmit and process input and output signals within automated systems.
- It is used in conjunction with the SV and VQC solenoid valve series and the components of the EX250 system.
- The SMC SI unit EX250-SAS3 is a serial input/output unit for AS-i networks in 31-slave mode.
- The unit has 8 inputs and 8 outputs, as well as two separate power supply systems.
- The integrated serial wiring facilitates easy installation and reduces the amount of wiring required.
- The SI unit complies with protection class IP67 and is compatible with digital input and output signals.
