Expansion I/O Units
Typical Applications:
Expansion I/O for WI-I/O 9 wireless units
Up to 31 x WI-I/O-EX-1-S units can be connected to each wireless unit via RS485 (up to 2 km long).
Serial I/O multiplexer
Transfer I/O via RS485— up to 32 units per multi-drop link
Expansion I/O for Modbus devices
Up to 31 x WI-I/O-EX-1-S units can be connected to each Modbus master via RS485 (up to 2 km long)
Features
Multi I/O channels— monitoring and control functions
Connected via RS485 multi-drop
Selectable communications via Modbus protocol (both RTU and ASCII formats)
Sensor signals connected at one module (input signals) are transmitted to another module where the signals are re-created as output signals, or passed via serial to a host device such as a PLC or SCADA system
Connect to WI-I/O 9 wireless I/O units for up to 31 serial addresses per wireless unit
Connect WI-I/O-EX-1-S units together to form a serial multi-drop I/O system - up to 32 serial addresses per multi-drop link—no Master device is required to control communications
Connect up to 99 x WI-I/O-EX-1-S units as multi-drop Modbus I/O (RS485 extenders/isolators required for more than 31 units per single multi-drop length)
RS485 multi-drop up to 2 km (1 mile) depending on installation environment
