Allen-Bradley 1785-V40V PLC-5 VME Processor Module

The 1785-V40V is a VME-based processor module belonging to the PLC-5 series, engineered to bring extensive control capabilities to industrial automation setups. This hardware unit executes critical data transfer applications and supports dual-mode configuration properties, allowing it to function seamlessly as either a master unit or a slave unit within an open-architecture VMEbus framework. By processing substantial input and output arrays across diverse manufacturing systems, the 1785-V40V manages complex computing sequences while maintaining localized serial interfacing with external peripheral instrumentation.

Features

• Integrates standalone programmable logic processing into standard VMEbus module formats
• Operates under flexible system design rules with dual master unit and slave unit runtime configurations
• Employs onboard static random-access memory (SRAM) storage to buffer and track automation logic blocks
• Supports deep integration with mixed field instrument networks via balanced digital and analog signal mapping

Applications

• Embedded VMEbus chassis process control and instrumentation
• High-density digital and analog automation infrastructures
• Multi-vendor multi-board computer network integration
• Dedicated master/slave data transfer arrangements

Installation Guidelines

• Backplane Insertion: Guide the hardware along the chassis tracks into the backplane connectors, confirming all terminal connections align perfectly before pushing the front latches.
• Electrical Safety: Ensure the host VMEbus assembly power source is fully turned off during any insertion or removal procedures to protect internal logic circuits from current transients.
• Environmental Control: Install the processor exclusively within regulated control enclosures where ambient thermal variables are consistently maintained from 0 to 40 degrees Celsius.
• Thermal Mitigation: Keep clear air vents around the unit chassis slot to effectively dissipate up to 21 Watts of power draw during heavy operations.
