Product Introduction

Maximizing rack density in VersaMax systems requires intelligent module selection, and the delivers exactly that by combining input and output capabilities in a single footprint. Functioning as a 32-point mixed module, it provides 16 sourcing transistor outputs and 16 versatile DC inputs, making it ideal for applications like conveyor control, packaging machines, and auxiliary process monitoring where I/O points are distributed but space is limited.

Designed for flexibility, the outputs are positive logic (sourcing), switching the load to the positive side of the DC supply. The inputs support both positive and negative logic, allowing seamless integration with diverse field devices without needing external signal conditioners. Individual green LEDs for every point provide instant visual diagnostics, significantly reducing troubleshooting time in the field.

 

Key Selling Points & Differentiators

• High-Density Mixed I/O: Combines 16 outputs and 16 inputs in one module, saving valuable VersaMax backplane slots and reducing wiring complexity.
• Versatile Input Logic: Supports both Positive and Negative logic inputs, eliminating the need for separate NPN/PNP modules in mixed-signal environments.
• Sourcing Output Architecture: 0.5A sourcing outputs are ideal for driving PLC inputs, relays, and solid-state switches directly without external pull-up resistors.
• Verified Functionality: Every undergoes point-by-point activation testing and load verification before shipping, complete with a signed test report.
• Not Recommended For: Do not use this module for high-current loads (>0.5A) or AC signals. For higher currents, use relay output modules; for AC, use dedicated AC I/O modules.
• Stock Availability: Current inventory is factory-sealed new surplus with traceable lot numbers; typically ships within 48 hours of order confirmation.
• Warranty Backed: Includes a 1-year functional warranty covering manufacturing defects and DOA conditions, with no restocking fees for verified failures.

FAQ

Yes. All units in stock have passed our 32-point activation and load tests. We ship same-day for orders placed before 2 PM EST, so you’ll have tracking before end of day.

The is compatible with all VersaMax CPUs and NIUs. It auto-configures via the backplane. Ensure your PLC program addresses the correct %I and %Q references for the slot it occupies.

What does “Sourcing” mean for the outputs?
Sourcing (Positive Logic) means the module provides the positive voltage to the load when active. The load must be wired between the output terminal and the negative/common rail. This is the standard for most modern DC sensors and PLC inputs.

Do I need to configure the input logic?
The module supports both positive and negative logic natively. Positive logic inputs receive current from the sensor; negative logic inputs sink current to the sensor. Verify your field wiring matches the logic type, but no software configuration is needed to switch modes.

What if the module fails within the warranty period?
We offer a no-questions-asked replacement for any verified manufacturing defect. Ship the failed unit back with your RMA number, and we’ll send a replacement within 24 hours of receipt.

Can this module handle inductive loads?
Yes, but with caution. The 0.5A rating is for resistive loads. For inductive loads (solenoids, relays), ensure the inrush current does not exceed 2.0A for <100ms and steady-state current is well below 0.5A. Always use flyback diodes across inductive loads to protect the output transistors.

Is this a refurbished or new surplus unit?
This is New Original (New Surplus) – factory sealed, never installed, with full traceability to the original manufacturing lot. It is not refurbished, repaired, or pulled from a decommissioned system. We provide the original manufacturer’s lot code upon request for your quality records.

 

Quality Transparency SOP

• Incoming Verification: Source traceability confirmed via lot code; anti-counterfeit visual inspection; serial number cross-referenced with OEM records; accessories verified.
• Live Bench Test: Dedicated VersaMax test rack; power-on self-check; 16-output activation test; 16-input signal injection; LED indicator validation; 24-hour continuous load test; signed test report generated.
• Electrical Tests: Insulation resistance verified at 500V megger (>10 MΩ); ground continuity confirmed; backplane power consumption validated.
• Firmware Verification: Hardware revision “F” verified; configuration parameters backed up and documented.
• Final QC & Packaging: QC sign-off; anti-static seal applied; shock protection installed; QC Passed label affixed with date and inspector ID.

Test photos and video available upon request. We never claim “100% failure-free” – we provide verified, tested units with documented performance.

 

Technical Risk Avoidance

• Missing Field Power: Risk: Outputs remain off despite PLC command. Prevention: Verify external field power is connected and the green “FLD PWR” LED is lit. Field Note: We’ve seen technicians replace modules because they forgot to wire the 24VDC field supply. Always check the FLD PWR LED first.
• Inductive Load Damage: Risk: Output transistor failure. Prevention: Install flyback diodes across all inductive loads. Field Note: Missing flyback diodes on solenoid valves caused premature output channel failure. Always protect inductive loads.
• Backplane Seating: Risk: Intermittent I/O communication. Prevention: Ensure the module is fully seated and locked onto the VersaMax backplane. Field Note: A partially seated module caused random channel zeros during panel vibration. Push firmly until the latch clicks.
• Logic Mismatch: Risk: Inputs always ON or always OFF. Prevention: Verify field wiring matches Positive/Negative logic requirements. Field Note: Wiring a PNP sensor to a Negative logic input caused the input to stay energized. Check sensor type vs. module logic.
• ESD Damage: Risk: Silent channel failure. Prevention: Use grounded wrist strap and anti-static mat during handling. Field Note: We’ve tested modules that passed power-on but had dead output channels after 48 hours due to ESD. Handle with care.
