The modular, rack-based Productivity2000 PLC system now has 47 discrete and analog I/O modules providing over 400 local I/O points. With remote expansion, over 4,000 total I/O points are available. New AC and DC discrete I/O modules include 8-point, 100-120 AC input and output modules, 8 and 15-point, 3.3-24 VDC input and output modules and 32-point,12-24 VDC high-density DC input modules. Starting as low as $47.00, these I/O modules easily connect to photo eyes, proximity sensors, limit switches, push buttons, light curtains, or any other discrete control device. Starting at $101.00, new 12-bit, 4-channel, current and voltage analog I/O modules are available with or without OLED message displays to measure and control process variables such as level, flow, and pressure. ZIPLinks wiring systems eliminate the need for hand wiring I/O modules.
