Frequently Asked Questions (FAQ)

• Is the terminal block included with the VS3202? Yes, this part number is a complete set including both the logic solver and the required terminal block.
• Can I replace a VS3202 while the safety system is online? Yes, the redundant architecture allows for hot-swapping one module while the partner solver maintains the safety loop.
• Does the module support ISA G3 corrosive environments? Absolutely. The internal boards are conformally coated to withstand harsh industrial contaminants.
• How do I configure the logic for the SLS 1508? Configuration is performed through the DeltaV SIS engineering environment using Function Block Diagrams.
• What is the typical lifespan of the VS3202 hardware? Based on field experience, these safety modules are built for 15-20 years of continuous operation in climate-controlled environments.

Selection and Purchasing Guide

• Step 1: Confirm your I/O count and loop criticality to determine the number of VS3202 pairs needed.
• Step 2: Verify that your DeltaV system version supports SIS SLS 1508 hardware.
• Step 3: Ensure your field power supply can handle the 4.0 A load maximum per solver.
