It provides highly reliable, regulated DC power to the Trusted chassis, main processors, and I/O modules in SIL3-rated safety applications such as emergency shutdown (ESD), fire and gas, burner management, and turbine control. The T8193 features true TMR architecture—three independent power supply circuits operating in parallel within a single module. If any one supply fails, the other two continue to power the system without interruption. Hot-swap capability allows replacement without shutting down the safety system. This unit is new surplus, factory-sealed in original ICS Triplex/Rockwell Automation packaging. Trusted components are engineered for the highest safety integrity; contact us for current stock and firm pricing. Frequently Asked Questions (FAQ) Q: What is the Trusted TMR system, and where is the T8193 used? A: Trusted TMR is ICS Triplex’s (now Rockwell Automation) high-integrity safety system platform, used for SIL3 applications in: Emergency shutdown (ESD) Fire and gas detection Burner management systems (BMS) Turbine and compressor control Critical process control Pipeline protection The ICS TRIPLEX T8193 is the power supply that provides reliable DC power to the entire Trusted chassis. Without it, nothing works. In safety systems, power supply reliability is as critical as the logic solver. Q: What does TMR mean on the T8193? A: TMR = Triple Modular Redundant. Inside the ICS TRIPLEX T8193, there are three independent, isolated power supply circuits operating in parallel. Each supply can power the entire Trusted chassis by itself. They share the load under normal conditions. If one supply fails (due to component failure, surge, etc.), the other two instantly take over with no interruption to the system. The failed supply can be hot-swapped while the system runs. This is critical for safety applications where power loss means loss of protection. Q: Is the T8193 a redundant power supply or does it require external redundancy? A: The T8193 itself is TMR—it has three internal supplies in one module. This provides internal redundancy. For external redundancy (protecting against loss of input power), you can connect two independent 24V DC sources to the module (if it supports dual feeds). The T8193 is designed for the highest availability: internal TMR covers internal failures; external dual feeds cover input power failures. In critical SIL3 applications, we use both. Q: What input voltage does the require? A: The ICS TRIPLEX T8193 accepts 24V DC nominal, with a range of 18-32V DC. This is standard industrial control voltage. The input should come from a reliable, safety-rated 24V DC source—typically redundant power supplies with battery backup. Do NOT connect AC power; it’s DC only. Verify your plant power before installation. Q: What do the front panel LEDs indicate on the? A: The has multiple status LEDs: POWER (green): Input power present DC OK (green): Output voltages within spec TMR OK (green): All three internal supplies healthy FAULT (red): Internal fault (one or more supplies failed, overtemp, etc.) In normal operation, POWER, DC OK, and TMR OK are green, FAULT off. If TMR OK goes off but DC OK remains green, one internal supply has failed—module is degraded but still working. Schedule replacement. If DC OK goes off, module has failed completely—replace immediately. Q: Is the hot-swappable? A: Yes. The ICS TRIPLEX T8193 supports hot-swapping (online replacement) in a Trusted TMR chassis. However: The module has internal TMR, so you’re replacing the entire triple supply When you remove the module, all three internal supplies go offline The chassis loses power during swap (unlike modules with external redundancy) For critical systems, ensure you have backup power or schedule during low-risk periods Procedure: Verify you have external redundancy (dual input feeds) if critical Remove faulty Insert new module Verify LEDs return to normal System restarts (brief power interruption) In practice, we schedule replacement during planned outages unless the system has dual power feeds to separate chassis. Q: What’s the typical failure mode for modules? A: In my experience with Trusted systems: One internal supply fails (TMR OK off, but module still works—most common) Capacitor aging—after 10-15 years in warm cabinets Input surge damage—lightning or switching transients on 24V DC lines Connector corrosion in harsh environments (offshore, chemical) The is built for safety systems, but nothing lasts forever. If TMR OK goes off, the module is degraded—replace at next opportunity. If DC OK goes off, replace immediately. In one refinery, we found a with two supplies failed (TMR OK off, DC OK still on)—still running on one supply! Replaced it ASAP. Q: Does the require configuration software? A: No. The is hardware-only—no software configuration. It simply provides power. However, the Trusted system monitors its status via the backplane. The safety controller can detect and report power supply faults, TMR status, and alarms to operators. This monitoring is automatic—no configuration required beyond standard system integration. Q: What cooling does the use? A: The uses convection cooling—no fan. This is intentional for safety systems: fans are moving parts that fail. Convection cooling means: No fan noise No moving parts to wear out Requires adequate airflow around the module Must not block ventilation slots In Trusted cabinets, we ensure proper spacing and airflow. The is rated for full load without fans, but don’t pack modules tightly without ventilation. In hot environments, cabinet cooling may be needed. Q: What’s the difference between and T8191? A: The is typically the main TMR power supply for the Trusted chassis. T8191 may be: A lower-power variant An older revision A different input voltage version Always match the exact part number from your existing system. In Trusted, power supply variants are critical—using the wrong one may not fit or may not provide adequate power. The is the standard for most Trusted installations. Check your system documentation. Q: Can the be used in SIL2 applications, or is it only for SIL3? A: It’s certified for SIL3, but you can use it in SIL2 applications—it’s overkill but works fine. The doesn’t care what safety level you’re targeting. However, its TMR architecture and diagnostics are designed for SIL3. If your application only needs SIL2, you’re paying for capability you don’t use. Many plants standardize on across all safety functions for spares commonality. That’s fine—the module doesn’t degrade in lower-SIL use. Q: What maintenance does the require? A: Minimal but critical: Annual visual inspection for bulging capacitors, discoloration, or odor Check input voltage quality (stable 24V DC ±10%) Verify all LEDs indicate normal during routine rounds Ensure ventilation slots are clear of dust In redundant power configurations, test failover periodically The is designed for long life, but preventive maintenance catches problems before they cause outages. In one chemical plant, we found a with elevated ripple during testing—replaced it proactively before failure. 1769-L23EQBFC1B PLC RINT-6621C PLC HCS02.1E-W0012-A-03-NNNN PLC 3508E PLC 3503E PLC S2MAL36600 PLC Email: [email protected] Phone: 86 15340683922 Sales:Wu Jiedong Our products are guaranteed for 1 year, with new and original production stopped and imported spare parts.
