A-B 1794-IE8

A-B 1794-IE8,namely Allen-Bradley 1794-IE8,is a Flex I/O analog input module.The following is a detailed introduction to it:

I.Basic features

Input channel:It has 8 voltage/current single-ended input channels.

Signal receiving range:It can receive current signals of 0 to 20mA,4 to 20mA,and voltage signals of±10VDC and 0 to 10VDC.

Resolution and accuracy:

Configured to 12-bit resolution in unipolar mode.

Configured to 11-bit resolution in bipolar mode.

The absolute accuracy is 0.20%full scale( 25°C).

Conversion rate:The conversion rate on all channels is 256 seconds(there may be a typo here.It should usually be the number of conversions per second or the conversion rate within a specific time,but based on the information provided,we understand that the module has a fixed conversion cycle or time).

Power supply requirements:External power supply voltage range is 10.5 to 31.2VDC,nominal power supply voltage is 24VDC,and 60mA power supply current is required.
