Description
TRICONEX 3604E Triple Modular Redundancy (TMR) Digital Output Module
TRICONEX 3604E is a highly reliable TMR triple digital output module used in the safety instrumented system SIS of TRICONEX Tricon. The module receives instructions from three main controllers and performs a two out of three vote to convert the internal interlocking logic of the system into a 24VDC on-site drive signal, driving on-site execution components such as solenoid valves, motor starters, alarm relays, etc; Each channel has a complete triple redundant hardware architecture, eliminating single point of failure and meeting SIL3 safety level. It is widely used in ESD emergency shutdown, F&G fire and gas, and HIPPS high-voltage protection safety circuits.

Core Features
- Triple Modular Redundancy & 2‑of‑3 Voting Every output channel contains three independent hardware circuits. Output is activated only when at least two of three processors issue consistent commands, preventing false trips or command loss caused by single component fault. Faulty slices can be isolated while the module keeps working without process interruption.
- Comprehensive Loop Diagnostics Supports output on‑state verification; can detect field wiring open‑circuit, short‑circuit and blown fuse. Diagnostics covers the whole safety loop from logic solver to field load, supporting predictive maintenance for safety instrumented functions.
- Optical Isolated Non‑Commoned Output 16 non‑commoned sourcing outputs with 1500 VDC galvanic isolation between channels. Eliminates cross‑channel interference and simplifies field wiring for multi‑group independent loads.
- Hot‑swappable & Mechanical Keying Module can be replaced online without system shutdown. Mechanical key prevents wrong‑slot insertion to avoid mis‑configuration risk.
