Hardware Specifications

Allen-Bradley Industrial Control and Bus Synchronization

The 2711-K6C5L1 terminal is engineered to interface directly with SLC 500, MicroLogix, and PLC-5 controllers via its embedded RS-232 port utilizing DH-485 communication protocol logic. Designed to manage point-to-point and multi-drop token passing across industrial serial networks, the internal hardware architecture maintains backplane bus communication velocity and real-time data frame synchronization. Channel-to-channel isolation and integrated surge suppression prevent ground loop noise from corrupting display registers or interrupt driven I/O exchanges during continuous industrial execution.

Frequently Asked Questions

Q: Can the RS-232 (DH-485) port on the 2711-K6C5L1 be directly connected to a standard PC RS-232 serial port for programming?

A: Direct connection requires an isolated point-to-point converter (such as a 1747-PIC or 1761-NET-AIC module) or proper RS-232 pinout configuration to properly handoff signal levels and token-passing timing required by the DH-485 driver layer.

Q: What power supply tolerance is permissible on the 24 VDC power terminals?

A: The internal power supply operates across an input voltage range of 18 VDC to 32 VDC. Exceeding 32 VDC will trigger internal overvoltage protection circuitry, while dropping below 18 VDC causes low-voltage brownout shutdown.

Field Installation Guidelines

1. Disconnect and lock out all 24 VDC power sources and serial communication lines prior to mounting or maintaining the terminal.
2. Prepare the enclosure mounting cutout according to standard PanelView 600 dimensional guidelines, ensuring clean edges free of burrs or metal filings.
3. Confirm that the rear bezel sealing gasket is undamaged and seated correctly to guarantee NEMA 4X / IP enclosure sealing compliance upon installation.
4. Position the unit into the panel cutout and secure it using the peripheral mounting clips, applying even tightening torque sequentially across all clamp screws.
5. Terminate the 24 VDC power supply wires to the terminal block with correct polarity, and ensure the protective conductor (earth ground) is bonded directly to the enclosure grounding busbar.
