I/O Modules for Arduino-Based PLCs

AutomationDirect has released new modules for the Productivity1000 PLC. These new lower-cost, high-resolution, four-channel analog input modules support 0-20 mA or 0-10V dc signals. The ProductivityOpen Arduino-based controller line now offers a 2-port serial communications shield that provides an interface between the ProOpen controller and serial networks/devices. The P1AM-Serial is housed in an industrialized Arduino MKR form factor and each 4-pin port supports RS-232 or RS-485 communication. A new lower-cost Productivity2000 base power supply is also available that accepts a 24V dc input and delivers a maximum of 45W.
