Description
Emerson 1C31222G01
Technical Specifications
- Output channel quantity: 16 discrete output channels
- Output form: dry contact relay output
- Rated relay contact capacity: 240VAC / 2A
- Operating temperature: 0°C to 60°C
- Storage temperature: -40°C to 85°C
- Ambient humidity: 5% to 95% non-condensing
- Channel isolation between different relay loops
Functional Features Each channel uses independent electromagnetic relay component. Relay state feedback function sends contact status back to monitoring system. Output loop overload protection reduces risk of relay damage. Open-circuit diagnosis capability monitors field wiring condition. One LED status indicator assigned for each channel. Supports configurable relay action logic for interlock application.
Application Scenarios Remote motor logic control, solenoid valve driving and alarm lamp output inside thermal power plant and chemical plant Ovation DCS control systems.
Performance Parameters
- Relay mechanical service life reaches 10 million operation cycles
- Relay actuation response time less than 15ms
- Stable contact performance under industrial vibration environment
- Surge suppression for relay coil circuit
Material Composition Flame-retardant plastic housing. Industrial grade electromagnetic relay components. Surge absorption diodes and resistors for coil protection. Gold plated backplane connector. Flame-retardant plastic terminal blocks.
Structural Characteristics Rack mount plug-in card construction. Front-side wiring terminal block for field output wiring. Front-panel channel-status LED indicators. Module locking buckle structure prevents loosening from vibration. Each relay channel is arranged in separated area to avoid cross channel interference.
Working Principle Controller transmits digital command over backplane bus to this output module. Internal logic circuit controls energization and de-energization of corresponding relay coil. Relay contacts close or open to switch field equipment power loop. The module feeds relay contact state information back to Ovation DCS system for monitoring purposes. Self-diagnosis circuit continuously checks relay driving circuit health.
Installation Requirements Mount onto Ovation DCS cabinet backplane. Keep field power wiring separated from control signal wiring. Tighten terminal block screws fully to avoid bad contact. Ensure cabinet protective grounding connection is reliable.
Use Precautions Do not exceed rated relay contact load capacity. When switching heavy inductive load equipment, install external surge suppression accessories. Test relay channels completely after installation. Replace module when relay contact adhesion or failure occurs. Avoid strong vibration environment.
