More Information

Overview Manuals VME Installation Extended-local I/O Thermal Control Application
  • Provides 48K words of user memory in the PLC-5/V40L VMEbus processor format
  • Supports one extended-local I/O port and as many as sixteen extended-local chassis
  • Requires 200 LFM forced-air cooling across the circuit board at the documented operating range

1785-V40L is the Allen-Bradley PLC-5/V40L processor for a VMEbus assembly.

Its architecture combines two DH+ or Remote I/O ports with one extended-local I/O port, 48K words of user memory, and one RS-232 interface.

Before replacement, preserve the VME slot and backplane details, application, channel assignments, rack plan, airflow, and power requirements.

Availability, condition, price, and shipping time for 1785-V40L are confirmed during quotation.

  • The official catalog number is 1785-V40L and the product designation is PLC-5/V40L.
  • The processor uses the documented VMEbus hardware format.
  • Slot, backplane, addressing, power, and connector details must match the host system.
  • One extended-local-I/O port distinguishes the V40L architecture.
  • The official table permits up to sixteen extended-local I/O chassis.
  • Extended-local and remote-I/O plans must be restored with the controller project.
  • The operating specification assumes 200 LFM forced air across the board.
  • Maximum processor power is documented as 21 W.
  • Airflow, temperature, and clearances should be verified before commissioning.
  • VMEbus control assemblies requiring the documented PLC-5/V40L processor format.
  • Systems combining remote I/O with an extended-local-I/O chassis network.
  • Board-level controller replacement where airflow, VME power, project, and rack records are retained.
Description
Allen-Bradley 1785-V40L is the official hardware catalog for the PLC-5/V40L processor; PLC-5/V40L is the product designation, not an added part of the catalog number.

The processor provides 48K words of user memory, two Data Highway Plus or remote-I/O ports, one extended-local-I/O port, one RS-232 port, and support for the documented VME and 1771 architecture.

Replacement planning should confirm the complete 1785-V40L nameplate, VME slot and backplane, forced-air requirement, extended-local chassis layout, remote-I/O rack plan, processor image, and communication-channel assignments.

Technical notes
1785-V40L replacement requires the exact V40L catalog, VME slot and power, 200 LFM airflow, saved PLC-5 project, extended-local chassis plan, remote-I/O racks, and communication assignments; standard PLC-5/40 is different.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Can Allen-Bradley 1785-V40L from another VME assembly be installed without checking the host system?
No. Confirm VME slot addressing, backplane power, connectors, airflow, extended-local-I/O use, communication assignments, and the saved PLC-5 application for the target assembly.
What VME details should be recorded before replacing Allen-Bradley 1785-V40L?
Capture the installed slot, backplane arrangement, power and airflow, board addressing, adjacent hardware, connectors, and any system-specific VME configuration.
Why does Allen-Bradley 1785-V40L require attention to forced-air cooling?
The official environmental specification states the operating range with 200 linear feet per minute of airflow across the circuit board.
What controller information should be saved before removing Allen-Bradley 1785-V40L?
Retain the PLC-5 project, data values, remote and extended-local I/O layouts, rack addresses, communication-channel modes, and serial settings.
Can Allen-Bradley 1785-V40L be replaced by a standard chassis PLC-5/40 processor?
Do not assume equivalence. The V40L uses a VMEbus format and includes an extended-local-I/O port, so mechanical, electrical, and application compatibility differ.
What should be checked if extended-local I/O is missing after an Allen-Bradley 1785-V40L change?
Verify the extended-local port configuration, chassis sequence, cable path, termination, rack addressing, power, and the restored processor project.
What should be tested after installing Allen-Bradley 1785-V40L in the repaired VME system?
Verify processor mode, project checksum, forced-air cooling, VME communication, remote and extended-local I/O, serial paths, peer messages, alarms, and a controlled machine operating cycle.
