PLC-5 Backplane and I/O Signal Characteristics
The 1771-OBN uses PLC-5 rack communication through the 1771 I/O chassis backplane. The module provides I/O density scaling with 32 sourcing outputs arranged as four groups of eight channels. The 330 mA backplane current requirement defines the chassis power loading for module operation.
The output interface supports DC actuator connections including discrete loads controlled by PLC logic. Current limiting characteristics and conformal coating are included in the module construction for electrical protection within the specified installation environment.
Frequently Asked Questions
Q: What output signal type does the 1771-OBN provide?
A: The 1771-OBN provides 32 high-true sourcing DC output channels operating with 10-30 VDC field voltage.
Q: What is the backplane current requirement of the module?
A: The module requires 330 mA backplane current from the PLC-5 1771 I/O chassis.
Q: What chassis mounting configuration is supported?
A: The 1771-OBN is designed for rack mounting in compatible 1771 I/O chassis systems.
Field Installation Guidelines
Install the 1771-OBN module into a compatible 1771 I/O chassis slot and verify rack power capacity before operation. Use the specified 1771-WH wiring arm for field connections.
Route DC output wiring separately from high-voltage AC conductors and high-noise signal cables. Connect field wiring with correct polarity for sourcing outputs and verify load current requirements against channel and module current ratings.
Maintain proper grounding practices for the chassis and cable shielding where applicable. Inspect terminal connections, module seating, and keying positions before applying system power.
