Description
Product Overview
The 7400208B-020 DI2301 Card Module from Triconex delivers high-speed digital input for safety-critical DCS systems. Designed for Tricon Systems v10–v11, this 32-channel module supports 24VDC inputs with ON/OFF thresholds of 15–30V and 0–5V respectively.
Each input channel in the 7400208B-020 DI2301 features 1500V AC/DC isolation and optical separation to prevent cross-channel interference. The module responds in under 10 milliseconds, ensuring rapid signal acquisition for shutdown and protection systems.
Its hot-swappable design allows technicians to replace the module without halting operations. Engineers rely on the 7400208B-020 DI2301 for continuous performance in refineries, offshore platforms, and chemical plants.
LED indicators provide per-channel diagnostics for quick fault identification. The module consumes just 130mA typical current while handling up to 200mA fault current, supporting energy-efficient installations.
