Product Description

The RH914SQ is a high-precision analog input interface module designed for the Foxboro I/A Series system architecture. It enables accurate conversion of field-generated analog signals into digital data for processing within the Distributed Control System (DCS). The module supports high-density signal integration and incorporates robust electrical isolation and noise rejection, ensuring stable and reliable measurements in electromagnetically noisy industrial environments.

With advanced A/D conversion circuitry, the RH914SQ delivers high linearity and low thermal drift, making it well suited for critical feedback control loops where process variables such as pressure, temperature, and flow require millisecond-level accuracy.

Technical Specifications

Application

The RH914SQ is widely used in process-critical industries where precise and stable analog measurement is essential. Typical applications include boiler control systems in power plants, reactor monitoring in chemical facilities, and distillation column control in refineries. Its rugged construction ensures long-term reliability in both control rooms and remote instrument enclosures.

Technical FAQ

How does the RH914SQ handle signal interference?
The module employs galvanic isolation and differential input filtering to eliminate ground loops and significantly reduce common-mode noise.

Is the RH914SQ compatible with older I/A Series hardware?
Yes. The RH914SQ is fully compatible with standard I/A Series baseplates and fieldbus communication modules, making it suitable for system expansions as well as legacy upgrades.
