1746-NR4 Allen Bradley

SLC 500 RTD/resistance input module has Four (4) channels available that are backplane-isolated. The module’s A/D conversion method is sigma-delta modulation.

Features:

• This module is compatible for installation to a fixed style or modular hardware SLC 500.
• Input filtering, particularly a low-pass digital filter that has programmable frequencies.
• LED (5) indicators made up of 1 indicator for the status of the module itself and 4 indicators for the module’s channels, with 1 indicator for every channel.
• RTD types compatible for this module are Nickel Iron, Nickel, Copper, and Platinum.
• Does not require an external power supply and it does a self-calibration automatically when the filter frequency, input type, or excitation current, or when a channel is enabled.
• It features Four (4) RTD inputs with each channel supporting a wide variety of RTD types.
• Compatible RTD types include Platinum (385) 100, 200, 500 and 1000; Platinum (3816) 100, 200, 500 and 1000; Copper (426) 10, Nickel (618) 120, Nickel (672) 120, and Nickel Iron (518) 604.
