Product Description
Overview
The KJ3102X1-BA1 (12P2093X132) is a high-performance Redundant High-Speed Pulse Input Card for the Emerson DeltaV™ Series 2 Distributed Control System (DCS). It is engineered to capture high-frequency pulse signals with precision, making it ideal for applications such as turbine speed monitoring, flow measurement, and other pulse-based instrumentation. Its redundant design ensures continuous operation in critical process environments.
Key Features
-
High-Speed Pulse Processing: Handles inputs up to 50 kHz, providing accurate frequency and totalization measurement.
-
Redundancy and Failover: When paired with an identical module, it provides seamless failover within milliseconds to maintain uninterrupted process control.
-
Hot-Swappable: Can be safely replaced without shutting down the DeltaV system in non-hazardous environments.
-
Versatile Signal Compatibility: Accepts dry contacts, voltage pulses, and specialized transmitters with programmable filtering to prevent false counts.
-
Channel-Level Diagnostics: Monitors each input channel for open circuits, short circuits, and general health, reporting status to the DeltaV controller.
-
Robust Industrial Design: Supports operation from -40°C to 70°C, with storage up to 85°C, and humidity tolerance from 5% to 95% non-condensing.
