Description
Product Overview
The Emerson KJ3002X1-BF1 is an 8-channel RTD input module for the DeltaV™ Distributed Control System (DCS). It converts signals from RTD, thermocouple, mV, and VDC sensors into accurate digital readings for the controller. Designed for industrial process control, it ensures reliable temperature monitoring and smooth integration with DeltaV M-series hardware.
Key Features
-
Multi-Sensor Compatibility: Supports RTD, thermocouple, mV, and VDC inputs.
-
Eight Channels: Measures multiple points simultaneously with high precision.
-
High Accuracy: ±0.1% full-scale for reliable data acquisition.
-
Rapid Update: Reads all eight inputs every 100 ms for near real-time control.
-
Shielding Included: Minimizes signal noise and electrical interference.
-
Compact Modular Design: 8-wide form factor for efficient carrier installation.
Performance Characteristics
Reliable Temperature Conversion
The module transforms analog sensor readings into stable digital values for DeltaV controllers, enabling precise process control and data logging.
Local Bus Integration
Powered by 12 VDC at 160 mA, the module draws only 1.5 W, making it energy-efficient while maintaining performance. The regulated internal bus isolates sensitive controller electronics from bulk 24 VDC supply fluctuations.
Redundancy and Hot-Swap Capability
When deployed in redundant configurations, the KJ3002X1-BF1 allows seamless failover:
-
If one module fails, the partner module immediately takes over the load.
-
Hot-swappable design ensures no process interruption during maintenance.
Industrial Reliability
-
Convection Cooling: Fanless architecture reduces mechanical failures and dust accumulation.
-
Wide Operating Range: Functions in temperatures from -40°C to +85°C and standard industrial humidity.
-
Rugged Construction: Meets EMI/RFI resistance standards, suitable for harsh environments.
