About ALLEN BRADLEY 1746-IB16K 16-Channel, 24V DC Discrete Sinking Digital Input Module

Core Technical Specifications

The technical parameters below apply to both the standard 1746-IB16 and the conformally coated 1746-IB16K variants:

• Inputs Per Module: 16 current sinking inputs arranged in 1 single common group.
• Operating Voltage Range: 10 to 30V DC (Nominal 24V DC).
• Backplane Current Draw: 50 mA to 85 mA at 5V DC (depending on the hardware series version); 0 mA at 24V DC.
• Signal Delay (Max): 8 milliseconds for both ON and OFF transition states.
• Off-State Voltage (Max): 5.0V DC.
• Off-State Current (Max): 1 mA.
• Nominal Input Current: 8 mA at 24V DC per channel.
• Thermal Dissipation: 0.2 Watts per input channel; 3.6 Watts maximum total module dissipation.
• Circuit Isolation: 500V DC optical electrical isolation between backplane logic circuitry and field-side communication.
• Wiring Options: Shipments typically support standard 1746-HT or 1746-HCA removable terminal blocks for fast maintenance swaps.
