1746-IG16

Product Overview

1746-IG16 is a TTL Input Module from Allen-Bradley’s SLC 500 series, designed for 5V DC logic-level signal interfacing in industrial control applications.

Electrical Specifications

• Voltage Category: 5V DC TTL signal input (sourcing)

• Operating Voltage: +5V to DC COM, range 4.5–5.5V DC

• Ripple (max): 50mV peak-to-peak

• Input Current: 3.7mA @ 5V DC nominal

• Off-State Voltage: 2–5.5V DC

• Off-State Current (max): 4.1mA

Module Configuration

• Number of Inputs: 16

• Points per Common: 16

• Signal Delay (max): On = 0.25ms; Off = 0.50ms

• Logic Note: TTL inputs are inverted (−0.2 to 0.8V DC = low voltage = True = ON). Use a NOT instruction in ladder logic for True = High operation.

Power and Consumption

• Backplane Current (5V DC): 0.140A

• Backplane Current (24V DC): 0.0A
