1771-IXE/D Allen-Bradley, Thermocouple/Millivolt Input Module

Description:

The 1771–IXE/D module senses up to 8 differential analog inputs and converts them to values compatible with Allen–Bradley programmable controllers.
This module’s features include:
• 8 input channels configurable for thermocouple input ranges or millivolt input ranges: Types E, J, K, T, R and S thermocouples and +100 millivolts
• two types of inputs allowed: 4 of one input type and 4 of another
• cold junction compensation
• scaling to selected temperature range in oC or oF
• temperature resolution of 1oC or 1oF, millivolt resolution to 10 microvolts
• user selectable high and low temperature alarms
• all features selectable through programming
• self–diagnostics and status reporting at power–up
• detection of open circuit if thermocouple fails
• automatic offset and gain calibration for each channel
• software calibration of all channels, eliminating potentiometers

You can configure the following features for the 1771–IXE/D module:
• type of input
• one or two input types
• oC or oF
• data format
• real time sampling
• alarming
• calibration
Configure your module for its intended operation by means of your programming terminal and write block transfers.
