TRICONEX 3700A Product Specification
Product Overview
The TRICONEX 3700A is a high-reliability redundant power supply module designed for TRICONEX’s Triple Modular Redundant (TMR) safety instrumented systems (SIS). It serves as the primary power source for critical components in these systems, converting alternating current (AC) from the mains into stable direct current (DC) to power processors, input/output (I/O) modules, and communication modules. This functionality is essential for maintaining continuous operation in safety-critical environments where even brief power interruptions could lead to catastrophic incidents.
The TRICONEX 3700A supports redundant configurations, allowing multiple units to operate in parallel. If one module fails, others automatically take over without disrupting power flow. This redundancy is a key feature for industries such as oil refineries and chemical plants, where system downtime is unacceptable. As part of TRICONEX’s TMR architecture, the TRICONEX 3700A integrates seamlessly with main processor modules like the TRICONEX 3008 and I/O modules such as the TRICONEX 3721, connecting via a backplane interface to ensure low-latency power distribution.
Built to withstand harsh industrial conditions, the TRICONEX 3700A operates in temperatures from 0°C to 60°C and handles humidity between 5% and 95% (non-condensing). Its compact design (254 mm × 165 mm × 102 mm) and lightweight structure (1.8 kg) make it easy to install in standard control cabinets. Whether in power generation facilities, mining operations, or pharmaceutical plants, the TRICONEX 3700A delivers consistent power to keep TMR systems running safely and efficiently.

Main Features and Advantages
Redundant power delivery: The TRICONEX 3700A can operate in parallel with up to two other units. This means if one module fails, the others immediately take over. No power interruption occurs. This is critical in oil refineries, where a power loss could disable emergency shutdown systems, leading to leaks or explosions.
Stable output: The TRICONEX 3700A provides precise DC voltages (5 VDC, 12 VDC, 24 VDC) with very little fluctuation. This protects sensitive TMR processors and I/O modules from voltage spikes. Stable power reduces the risk of data errors or module damage in high-precision systems.
Wide input range: It accepts 85–264 VAC input. This allows it to work with different power grids worldwide. It works with 110 VAC in North America and 220 VAC in Europe. No extra voltage converters are needed, simplifying installation in global facilities.
Built-in protection: The TRICONEX 3700A has multiple safeguards. Overvoltage protection triggers if input exceeds 264 VAC. Overcurrent protection shuts down outputs during short circuits. Reverse polarity protection prevents damage from wrong wiring, which is common during maintenance.
Easy integration: Designed for TRICONEX TMR systems, the TRICONEX 3700A connects directly to the system backplane. No extra wiring is needed to communicate with processors. Its small size fits in standard 19-inch racks, saving space in crowded control cabinets.

Installation and Maintenance
Pre-installation preparations: Before installing the TRICONEX 3700A, turn off power to the TMR system. Check that the input voltage (85–264 VAC) matches the facility’s power supply. Mount the module in a 19-inch rack using the provided brackets. Make sure it is secure to resist vibration. Connect AC input cables to the L/N terminals. Connect DC output cables to the backplane. Tighten all terminals to prevent loose connections. For redundant setups, link modules using the parallel connection port.
Maintenance suggestions: Inspect the TRICONEX 3700A every month. Check the LED indicators. A green light means normal operation. A red light indicates a fault, such as an overcurrent. Clean dust from the vents with compressed air to keep it cool. Test redundancy every three months. Disconnect one module to ensure others take over without interrupting power. Replace the module if output voltages drift more than ±5% from the rated values. This indicates component wear.
Application Fields
In oil and gas: The TRICONEX 3700A powers TMR systems in offshore platforms. It supplies power to emergency shutdown modules. Its redundancy ensures these modules work during storms or power surges. This prevents oil spills and protects workers.
