AutomationDirect’s Productivity2000 programmable controller line includes additional low-cost discrete and analog input and output modules. AC and DC discrete I/O modules include 8-point, 100-120 VAC input and output modules, 8 and 15-point, 3.3-24 VDC input and output modules and high-density, 32-point,12-24 VDC input modules. These I/O modules allow easy connections for photo eyes, proximity sensors, limit switches, pushbuttons, light curtains, or any other discrete control device. 12-bit, low-resolution, 4-channel, current and voltage analog I/O modules are available to precisely measure and control process variables such as level, flow, and pressure.
