1C31116G04 analog input module

1C31116G04 is an analog input module designed by Westinghouse (later integrated into Emerson's product line) specifically for the Ovation Distributed Control System. It is dedicated to high-precision acquisition and conversion of on-site analog signals, and is widely used in various harsh industrial scenarios. The detailed information is as follows:

Core Technical Specifications

Parameter	Details
Number of Channels	8 independent isolated input channels, which can avoid signal interference between different channels and improve data collection stability.
Input Signal Types	Mainly supports 4 - 20mA current signals; some configurations can also be compatible with voltage signals, and there are also versions matching the ±1V voltage input range.
Measurement Accuracy	At 25°C, the accuracy is ±0.1% of the full scale plus ±1/2 least significant bit, with a confidence level of 99.7%; the temperature coefficient is ±0.24% of the full scale in the range of 0 - 60°C, ensuring measurement accuracy under temperature changes.
Resolution	14 - bit resolution for current signal input groups, and 13 - bit resolution with sign for voltage signal input groups, which can capture small changes in analog signals.
Sampling Rate	When configured for 60Hz interference suppression, the minimum sampling rate is 20 times per second; when configured for 50Hz interference suppression, the minimum sampling rate is 25 times per second, meeting the real - time data acquisition needs of general industrial processes.
Isolation Performance	The isolation voltage between channels and between channels and logic circuits can reach 1000V AC/DC, which can effectively prevent ground loops and electromagnetic interference in industrial environments from damaging the module.
Power Supply	Adopts 24V DC power supply, with a power consumption of about 5W, which can be well matched with the power supply module of the Ovation system rack.
