Product Short Description
Product Name: Ovation Discrete Input/Output or Contact Input Module (commonly 24 V DC contact input or relay output variant in 1C31 family).
Product Introduction: Digital I/O module for Ovation DCS handling discrete field contacts, solenoid drive or status acquisition depending on assigned G01 revision. Treated here as 24 V DC isolated contact input module commonly paired with Ovation terminal assemblies.
Description
Technical Specifications (typical for 1C31 digital family):
- Channels: 16 or 32 depending on exact subgroup
- Input Voltage: 24 V DC nominal (12–30 V DC window for contact input type)
- Isolation: 500–1500 V DC field-to-backplane
- Response: <5 ms
- Backplane: 24 V DC
- Operating Temp: 0–60 °C
- Hot Swap: Yes
- Mount: Ovation I/O chassis 1U
Functional Features: LED per channel, debounce filtering, wiredetect on some revisions, software force/override.
Application Scenarios: Motor run/stop feedback, limit switch status, pump trip logic, breaker auxiliary contact acquisition.
Structure & Material: Ovation 1U card, optocoupler isolated inputs, plastic housing.
Working Principle: Field contact closes 24 V DC path through optocoupler, controller reads boolean state, applies debounce and alarm filtering.
Installation Requirements: Ovation chassis slot, 24 V DC field supply independent of backplane, shielded cable separated from analog.
Usage Notes: Verify sink/source wiring with terminal block type. Do not mix 120 V AC field wiring on DC-rated module.
