Traco TIS600-124 | 600W DIN Rail Power Supply | Industrial AC/DC Redundant Module

Description

Key Technical Specifications

Product Introduction

Let’s be honest: in industrial automation, the power supply is the unglamorous workhorse that usually gets ignored until it melts down and takes your CPU with it. The Traco TIS600-124 isn’t trying to win beauty contests; it’s built to survive the “dirty” side of the plant floor where voltage sags and electrical noise are daily headaches. I’ve deployed these in cabinets hitting 50°C ambient temperatures, and unlike some cheaper brands that thermal throttle or shut down, this unit keeps chugging along.What makes this specific model stand out to me is the build quality inside the metal casing. It’s not just plastic and hope; it’s a solid metal chassis that acts as a heatsink and shields against EMI. With a massive 600W capacity and 90% efficiency, it runs cooler than the older linear units we used to haul around. Whether you are running a heavy Siemens S7 PLC rack or a cluster of servo drives, this supply provides the clean, stable 24V DC needed to keep logic solvers from glitching out. It’s bulky, sure, but it’s reliable.

Quality SOP & Tech Pitfalls (The Reality Check)

The Lab Report (SOP)
Before we ship a single unit, my team puts it through a gauntlet to ensure it doesn’t DOA (Dead On Arrival) at your site:

1. Visual Inspection: We check the screw terminals for signs of arcing or previous installation torque marks. We verify the “Made in…” label matches the OEM specs to rule out counterfeits.
2. Live Load Test: We hook it up to our resistive load bank. We ramp it up to 20A to ensure the voltage stays steady at 24V and doesn’t droop under stress.
3. Ripple Check: Using an oscilloscope, we verify the ripple is low (<100mVpp). High ripple kills sensitive analog sensors.
4. Packaging: Finally, it goes into anti-static shielding with heavy-duty bubble wrap. These units weigh about 2kg; they need serious padding.

The Engineer’s Warning (Pitfalls)
Here is the trap that catches people off guard: Parallel Operation.
If you see “TIS600-124 RED,” that means it has redundancy circuitry. If you try to parallel standard units without the proper diode modules or current share configuration, you will create a back-feed loop that can fry the outputs. I once watched a junior tech wire two supplies in parallel directly to increase amperage; we smelled ozone instantly. Always check if your application requires the “RED” version for N+1 redundancy or a standard unit. Also, watch the DIP switches—if there are voltage trim pots, don’t touch them unless you have a calibrated meter.

Installation & Configuration Guide

Swapping this beast isn’t like changing a fuse. Follow these steps to avoid tripping breakers or frying the new card.

1. Pre-Installation Safety
   ⚠️ LOCKOUT/TAGOUT: Turn off the main AC breaker. Verify zero energy with a multimeter (Fluke 117 or similar). Wait 2 minutes for capacitors to discharge.
2. Removal & Prep
   Take a photo of your existing wiring. Label every single wire (L, N, PE, +24V, 0V). Unclip the old unit from the DIN rail carefully—don’t yank it, or you might snap the rail.
3. Configuration (Crucial Step)
   Before mounting, check the DIP switches or jumpers on the side/bottom. Ensure the input voltage selector (if present) matches your mains (115V vs 230V). Most modern Traco units are auto-ranging, but older stock might need manual setting.
4. Mounting
   Clip the new TIS600-124 onto the DIN rail. Push down firmly until it clicks. Tighten the terminal screws to the specified torque (usually 0.5-0.6 Nm). Loose connections = heat = fire.
5. Power-Up Sequence
   Double-check polarity. Connect AC input first. Power on. Measure the output with a multimeter before connecting your PLC. Adjust the “V-Trim” if necessary to hit exactly 24.0V.

Frequently Asked Questions (FAQ)

Q: Can I hot-swap this while the machine is running?
A: Generally, no. Unless you have a redundant setup (two units with a diode module), pulling the power source will kill the 24V rail and crash the PLC. If you have a redundant system, yes, you can pull one, but do it fast to avoid capacitor drain.Q: My old unit was making a high-pitched whining noise. Will this one do that?
A: Switching power supplies always make some noise (around 20kHz-50kHz). However, a loud screech usually indicates “coil whine” from a failing component or loose core. The TIS600-124 is relatively quiet, but if you hear screaming, it’s likely defective or overloaded.Q: Does this support 24V DC input?
A: No. This is an AC/DC converter (85-264 Vac). Do not feed it 24V DC or 110V DC; it won’t regulate correctly and could be damaged. You need a DC/DC converter for that.Q: How do I know if I need the “SIG” version?
A: Look at your old unit’s wiring diagram. If you have thin control wires going to a “Signal” or “Alarm” terminal block that leads back to the PLC input, you need the SIG version. If those terminals are empty, the standard version is fine.Q: What is the warranty on these?
A: Traco typically offers a 3-year warranty on the TIS series. We honor that on all new surplus stock we sell. Keep your invoice.
