Detailed content
-
Functional Features:
-
Input Type: Supports both dry contact and wet contact (sinking/sourcing) inputs.
-
Redundancy: TMR architecture; each input signal is read by three separate controllers for voting and fault detection.
-
Filtering: Onboard hardware filtering and debouncing to eliminate signal noise and chatter from mechanical switches.
-
Diagnostics: Includes wire-break detection and short-circuit monitoring.
-
-
Technical Specifications:
-
Input Voltage: 24VDC nominal (range typically 18-32VDC).
-
Input Current: Approximately 7mA per channel.
-
Isolation: Group isolation between input channels and the logic level.
-
-
Application Scenarios: Essential for gathering status data from emergency stop buttons, limit switches, pressure switches (e.g., low lube oil pressure), and valve position feedback switches in gas and steam turbines.
-
Structural Features: Heavy-duty screw terminals for secure field wiring. The board includes test points for troubleshooting voltage levels without disconnecting wires.
