RIO Remote I/O

PLC with connection terminals

The RIO-47300-PLC is a DIN rail mounting unit with screw terminals and Ethernet connection. A RIO contains a fast RISC processor to handle the I/O logic and is programmed using Galil's intuitive command language or Galil's Ladder Interface software.

Each RIO unit has numerous analog and digital I/O, including 48 optically isolated high performance I/O (72 with extended I/O option), 16 user configurable analog I/O and two Ethernet ports. The RIO-47300 has an expanded memory with 400 lines of program storage, 254 variables, 1000 array elements, 6 PID control loops and 5 Ethernet handles.

The RIO-47300 model has an internal switch with two Ethernet ports that allow daisy chaining of RIO units without an external switch. It can also easily communicate with other devices, including Galil's DMC-40x0, DMC-41x3 and DMC-30000 motion controllers.
