On the heels of the recently released RIO-47142 comes the new RIO-47300 which is an expanded model that includes two Ethernet ports, more I/O, and screw terminals.The RIO-47300's Ethernet ports allow an unlimited number of RIOs to be daisy-chained together without an external Ethernet switch. The RIO-47300's memory allows 400 program lines, 254 variables, 1000 array elements, 6 PID control loops and 5 Ethernet handles. Digital inputs and outputs on the RIO-47300 are increased from 16 to 24 each for a total of 48 optically isolated digital I/O. All the digital outputs are high-power 500mA outputs. The 16 analog inputs and outputs are user-configurable for +/-10V, +/-5V, 0-10V or 0-5V. For more details - see this Comparison of Screw Terminal RIOs: RIO-47200 and RIO-47300
