Product Details Introduction

1785-V40L processor module (PLC-5/V40L VMEbus)

1785-V40L is a VMEbus architecture processor module of the Rockwell Allen Bradley PLC-5 series, designed for medium to large industrial control systems, providing stable control and multi network communication capabilities.

Core parameters (plain text, no links)

Model: 1785-V40L, PLC-5/V40L VMEbus processor.

Processor architecture: Based on Intel 80386, 33 MHz clock speed, 16 bit control architecture.

User memory: 48K words of SRAM (program/data table), 64 KB of VME bus memory.

Total I/O capability: Maximum 1920 I/O points (any mix), complementary I/O is 1920 in+1920 out.

Analog I/O: Supports up to 1920 analog I/O.

Communication port:

2 DH+/remote I/O channels, configurable as DH+nodes or remote I/O scanners/adapters.

1 RS-232 serial port (25 pin D-Sub), used for programming, monitoring, and communication with the upper computer.

1 extended local I/O port, supporting the expansion of local I/O racks.

Rack expansion:

Supports up to 15 I/O racks (local+remote).

Expand up to 16 racks for local I/O and up to 60 racks for remote I/O links.

Remote I/O speed: Supports three speeds: 57.6 kbps, 115.2 kbps, and 230.4 kbps.

Program scanning: Bit logic is approximately 0.5 ms/1000 words, typical scanning is 2 ms/1000 words.

Power supply and power consumption: VME backplane 5V DC power supply, typical current 2.9A, maximum 3.5A; power consumption 16-21W.

Physical specifications: VME standard size, weighing approximately 0.71-1.36 kg, occupying one VME slot.

Status indication: onboard LED, displaying operation, fault, communication, and I/O status.

Environmental parameters: working temperature 0-60 ° C, humidity 5% -95%, no condensation, industrial grade anti-interference.

Product status: discontinued, mainly for refurbishment/spare parts in the market, used for maintenance of old VME architecture PLC-5 systems.

Typical applications: Industrial scenarios such as power, metallurgy, rail transit, and large-scale production lines that require VME bus, medium to large-scale I/O, and multi network communication.

The 1785-V40L is the mainstream mid to high end processor of the PLC-5 VME series, with core advantages of VME bus compatibility, 48K memory, 1920 point I/O, and dual DH+channels.
