ABB Ovation™ PPD series modules are high-performance I/O modules specially designed for Ovation Distributed Control System (DCS), which are used for signal acquisition, conditioning and output in industrial process control. With high precision, strong isolation and modular design as the core, this series of modules are suitable for harsh industrial environments such as electric power, petrochemical industry and water treatment.
Product features
Analog output: Support standard signals such as 4-20mA and 0-10V, with an accuracy of ±0.1% FS (full scale).
Channel isolation: the isolation voltage between channels is ≥500V, which effectively suppresses the ground loop interference.
Redundancy configuration: optional dual-module hot standby, switching time < 100ms, ensuring system continuity.
application area
Boiler control: water supply valve opening adjustment (driven by 4-20mA signal).
Speed regulation of steam turbine: analog output to servo actuator.
Substation automation: communicate with protection relay (via Modbus RTU).
Pressure control of reaction kettle: PID algorithm is output to electro-hydraulic regulating valve.
Pipeline flow management: multi-channel coordinated control of pump speed and valve.
Dosing pump control: dynamically adjust dosage according to water quality feedback.
Pumping station scheduling: digital output starts and stops large centrifugal pumps.
