Specs & Technical Data
Specifications: Allen-Bradley 1771-IT PLC-5 Digital DC (12-24V) Fast Response Input Module, Number of Inputs: 8; Input Voltage, Nom: 12-24V DC; Input Voltage Range: Logic 0 - 0V min to 4V max, Logic 1 - 10V min to 27V max; Input Current, Nom: 8mA @ 12V DC, 24mA @ 24V DC; Input Impedance: 1-2 KOhms Max (On-State), 2-3 KOhms Max (Off-State); Input Signal Delay: 0.6ms (+/-0.2ms) On-to-Off; Wiring Arm: 1771-WA; Backplane Current Load: 74mA @ 5V DC. 
Miscellaneous: Allen-Bradley 1771-IT module should be used with devices that benefit from very short delay times, such as: Photoelectric Switches, Incremental Encoders, DC Proximity Switches. The 1771-IT module may not be suitable for use with hard contact devices because its fast response could register contact sources as input data. A DC input module (Cat. No. 1771–IB) is recommended for interfacing with hard contacts. The delay due to filtering is nominally 1ms for turning DC inputs On or Off.
