1746-NI4 AB PLC 25mA 4 Number of Inputs Analog I/O Modules 1746 Series Original brand new

Features

Hardware-platform sharing makes spare-parts stocking convenient.Combinations of input and outputs in the same digital and analog modules provide expansion capabilities without sacrificing space or increasing cost.Variety of voltages creates a precise power fit for your application.No need to disconnect wiring to replace module of 16 or more I/O; removable terminal blocks are shipped with I/O modules.Broad range of signal interfaces to AC and DC sensors/actuators for a wide variety of applications.LED indicators show input/output status for easier troubleshooting.Modules available in different densities (32 I/O per module max) for greater flexibility and cost savings.1746 I/O modules include optical coupling and filter circuitry for signal noise reduction.A wide range of analog signal levels including standard analog inputs and outputs, and direct thermocouple and RTD temperature inputs.
