PDM-10 Other Names:
Input/Output Card PDM-10
PDM-10 Digital Module
Analog Module PDM-10
Basic Attributes
Model Positioning: This is a relay card/module for industrial control systems, commonly used in DCS distributed control systems, PLC programmable logic controllers, and marine automation equipment (such as vacuum toilet systems and diesel engine control modules).
Compatibility: Compatible with Wartsila engines, generator sets, and marine propulsion systems. In some cases, it is used with vacuum toilet drain valves and actuators.
Technical Parameters and Features
Electrical Specifications:
Output Channels: Typical configuration is 16 channels (e.g., RPC2223 module), supporting a voltage range of 24V DC/AC to 230V AC.
Isolation Performance: Coil-to-contact isolation voltage reaches 3000VAC, contact-to-contact isolation voltage is 750VAC, and leakage current is ≤1mA, ensuring electrical safety.
Contact Rating: 2A for resistive loads, derating required for inductive loads. Mechanical life is over 10 million cycles at no load and approximately 100,000 cycles at rated load.
Response Time: Contact switching delay is <10ms, supporting low-frequency control (e.g., 1Hz switching frequency).
Environmental Adaptability: Operating temperature: 0-55°C, storage temperature: -40-70°C, humidity: 5%-95% non-condensing, suitable for harsh marine and industrial environments.
Interfaces and Communication: Supports RS232/RS485 interfaces and is compatible with protocols such as Modbus, Profibus, and Ethernet, facilitating integration into automation systems.
Application Scenarios and Case Studies
Marine: Used in Wartsila diesel engine control systems (such as the RM-11A relay module), vacuum toilet systems (such as drain valves and flush controllers), and thruster control.
Industrial Automation: Used as a switch output module in DCS/PLC systems to control actuators such as motors, valves, and pumps.
Supporting Equipment: Often works in conjunction with Wartsila vacuum pumps, sensors, and actuators (such as horn valves, check valves, and cup assemblies) to ensure stable system operation.
