- Hot-Swappable: Supports replacement without powering down the rack.
Application Scenarios
Used to interface the 3500 protection system with plant DCS, ESD systems, or to directly trip machinery drivers.
Performance Parameters
- Contact Rating: 30 Vdc / 2 A
- Operating Temperature: -30°C to +65°C
Material Composition
Industrial-grade enclosure with high-reliability electromechanical relays and conformal-coated internal circuitry.
Structural Characteristics
Standard 3500 module size with front-panel relay status LEDs and rear terminal connections.
Working Principle
Receives digital alarm states via the 3500 backplane bus, evaluates programmed logic, and energizes or de-energizes the mechanical relays accordingly.
Installation Requirements
Insert into an available slot in the 3500 rack. Wire field loads according to specified voltage and current ratings.
Precautions for Use
Verify relay logic configurations in the software before energizing field loads. Ensure proper snubber circuits are installed if switching inductive loads.
