Description
Product Overview
The 7400221-100 PI2381 Pulse Input Baseplate from Triconex delivers precise pulse counting and frequency measurement for safety-critical DCS systems. Built for Tricon Systems v11, this 16-channel module supports 5–30V DC inputs with 24-bit resolution and ±0.01% frequency accuracy.
Each channel in the 7400221-100 PI2381 provides 1500V AC/DC isolation, ensuring signal integrity in noisy environments. The module handles up to 10kHz input rates, making it ideal for turbine speed monitoring and compressor control.
Its hot-swappable design allows technicians to perform maintenance without interrupting operations. The module operates across a wide -40°C to +70°C range and tolerates storage temperatures up to 85°C.
Advanced signal conditioning and noise rejection enable reliable RPM detection in electromagnetic-heavy environments. Engineers value the 7400221-100 PI2381 for its compact footprint, low power consumption, and seamless integration with TRISTATION 1131 tools.
