VMF-IOC4T Analog/Digital I/O Board | Core Applications
Function: Provides 4-channel isolated signal interfacing between VM600 monitoring modules and field devices/control systems. Version 200-560-101-017 = standard I/O, 200-560-000-111 = redundant configuration.
Typical Application Scope
-
Signal Integration
- Analog Inputs (4x):
- 4–20mA sensors (pressure, temperature)
- ±10V vibration transducers
- HART-enabled devices (with VM600 QuickCal)
- Digital Inputs/Outputs (4x configurable):
- Trip/status signals (e.g., lube oil pump failure)
- Relay commands (start/stop sequences)
- Analog Inputs (4x):
-
System Roles
- Safety Interfacing: SIL2/PLe safety logic solver integration (e.g., emergency shutdown commands via DO)
- Legacy Retrofit: Connect non-VM600 devices (e.g., third-party PLCs) to VM600 racks
- Redundancy Bridge: Cross-communication path for paired VMPx controllers (requires
-000-111version)
Industry Use Cases
| Sector | Implementation Example |
|---|---|
| Power Generation | Gas turbine lube oil monitoring: – AI1: Bearing temp (PT100) – DI1: Oil pressure switch – DO1: Auxiliary pump start |
| Oil & Gas | Compressor surge control: – AI2: Discharge pressure (4–20MPa) – DO2: Anti-surge valve trigger |
| Hydro Turbines | Guide bearing supervision: – AI3: Radial vibration (Velomitor sensor) – DI3: Cooling water flow status |
| Marine | Diesel engine protection: – AI4: Exhaust temp (K-type thermocouple) – DO4: Fuel cutoff |
Critical Configuration Notes
| Parameter | Requirement |
|---|---|
| HART Support | Enable via VM600 ConfigTool (requires FSK module) |
| Redundancy Sync | Use optical cable (ST connector) between -000-111 boards |
| Isolation | 500V channel-to-channel / 1500V channel-to-backplane |
| Environmental | -40°C to +85°C (condensation prohibited) |
