PRODUCT INFORMATION
Product Overview
The Allen-Bradley 1771-IQ16 PLC-5 Digital Input Module provides discrete signal acquisition for industrial control architectures. It interfaces discrete electrical and mechanical devices directly to the controller module for logic execution. The module converts incoming DC voltage signals into binary digital data. This data stores directly into the programmable memory of the controller. Sixteen isolated input channels protect system logic from field-side electrical disturbances.
This module operates over a DC voltage range of 10 to 32 volts. Nominal input operating voltage is rated at 24 volts DC. The unit operates on a backplane current draw of 100 milliamperes. Maximum power dissipation is 15.0 watts, while minimum dissipation is 0.5 watts. Thermal dissipation ranges between 1.7 BTU per hour and 51.0 BTU per hour. External field wiring connects via a removable wiring arm to simplify replacement.
