Product Introduction
The MTL 8910-PS-DC is a redundant power supply module designed specifically for the MTL 8000 series of intrinsically safe interface systems. It ensures continuous power delivery to the I/O modules, preventing system downtime caused by single power source failures. This unit is critical for process control applications where reliability is non-negotiable.In terms of electrical performance, the module handles a 24VDC input and delivers a stable 2A output to the backplane. The redundant design means that if one power feed fails, the other takes over immediately without interruption. This specific architecture significantly reduces the risk of total system failure in hazardous areas, providing a measurable increase in operational uptime.
Installation & Configuration Guide
Preparation (10 min)
- Verify the backplane model matches the MTL 8000 series.
- Ensure the 24VDC power source is disconnected.
- Check the module for physical damage (cracks in casing, bent pins).
Removal (5–10 min)
- Depress the locking clip at the bottom of the unit.
- Gently pull the module away from the backplane.
- Do not force it; the connectors are keyed.
Installation (10 min)
- Align the module with the designated slot on the backplane.
- Push firmly until the connector seats fully.
- Engage the locking clip to secure the unit.
Power-On & Test (10 min)
- Apply 24VDC power.
- Check the LED indicator on the front face.
- It should light up (usually green) to indicate valid power.
- Measure the output voltage at the test points if possible.
Troubleshooting Quick Reference
| Symptom | Probable Cause | Action |
|---|---|---|
| LED Off | No input power | Check 24VDC supply wiring and fuse. |
| LED Red/Flickering | Module Fault | Replace the 8910-PS-DC unit. |
| System Intermittent | Loose connection | Reseat the module on the backplane. |
| Low Voltage | Overloaded backplane | Calculate total current draw of I/O modules. |
Dimensions, Mounting & Wiring Notes
- Dimensions: Standard MTL 8000 footprint (approx. 115mm height).
- Mounting: Clips directly onto the MTL 8000 backplane.
- Wiring: Input terminals are typically located at the bottom or top (verify with terminal diagram).
- Note: Ensure terminal screws are torqued to spec to prevent arcing.
FAQ (5–7 questions)
Q1: Is this unit new or refurbished?
A: We stock both. Most units are “New Surplus” (unused but older stock) or “Tested Refurbished.” Please check the specific listing for the exact condition.Q2: Can I use this with MTL 5000 series?
A: No. The 8910-PS-DC is designed strictly for the MTL 8000 backplane architecture. The connectors and pinout are different for the 5000 series.Q3: What does the LED status mean?
A: A solid Green LED typically indicates healthy 24VDC input and output. A Red or Off LED suggests a fault or lack of power.Q4: Do you offer a warranty?
A: Yes, we provide a 12-month warranty on all power supply units. This covers functional failures under normal use.Q5: How do I verify redundancy is working?
A: You need to simulate a power loss on the primary feed. The system should stay active without resetting. (Do this only during scheduled maintenance).Q6: I need this urgently. How fast can you ship?
A: We usually ship within 24 hours of receiving payment. Express shipping options are available at checkout.
