PRODUCT INFORMATION
Product Overview
Revision scope: These specifications describe 1762-IQ16/A (Series A). Check the corresponding technical data before specifying another hardware series.
The Allen-Bradley 1762-IQ16 MicroLogix Digital Input Module provides discrete 24 V DC sensing. It offers sixteen discrete input points for industrial automation systems. The inputs support sink or source wiring configurations. The standard operating voltage ranges from 10 to 30 V DC. Ambient temperature operation up to 55 degrees Celsius derates voltage to 26.4 V DC.
The sixteen digital inputs are divided into two isolated groups. Group zero covers channels 0 through 7. Group one covers channels 8 through 15. Group-to-backplane electrical isolation is factory tested at 1697 V DC for one second. Both on-state and off-state transitions have a maximum signal delay of 8 milliseconds. The physical module structure conforms to an IP20 environmental enclosure rating.
