Q: What is the primary function of the 1771-IBD-B module?

A: The 1771-IBD-B is a 16-point digital DC input module that converts 10-30V DC discrete signals from field devices into logic-level signals for PLC-5 processors.

Q: Does the 1771-IBD-B support source or sink wiring configurations?

A: The 1771-IBD-B features a sink input configuration, meaning current flows from a sourcing PNP field device into the input terminal.

Q: How do you configure the hardware filter times on the 1771-IBD-B? 

A: You must position the onboard jumpers located on the 1771-IBD-B circuit board to select either a 1 ms or 6 ms filter time.

Q: Can the 1771-IBD-B be hot-swapped during system operation?

A: Yes, the 1771-IBD-B supports RIUP (Removal and Insertion Under Power), allowing module replacement without turning off backplane power in non-hazardous locations.

Q: Which wiring arm is required to connect field signals to the 1771-IBD-B?

A: The 1771-IBD-B requires the 1771-WH edge-connector wiring arm to allow module swaps without disconnecting individual field wires.

Q: What do the front-panel status LEDs on the 1771-IBD-B indicate? 

A: The 16 red LEDs on the front face of the 1771-IBD-B provide real-time visual verification of the ON or OFF state of each input channel.

Q: What is the maximum off-state leakage current for sensors wired to the 1771-IBD-B?

A: Connected proximity or photoelectric sensors must not exceed a maximum off-state leakage current of 1.7 mA to prevent the 1771-IBD-B from sticking ON.

Q: Is the 1771-IBD-B compatible with all Allen-Bradley 1771 chassis? 

A: The 1771-IBD-B is compatible with standard 1771 I/O chassis but cannot be used in obsolete 1771-A1, 1771-A2, or 1771-A4 models.
