Description
Foxboro SAC-RL100-M11
Technical Specifications:
- Type: Signal Accessory Cable with Relay
- Length: Standard length (typically 1 meter or 10 feet, check specific model)
- Connector Type: Custom Foxboro connectors on one or both ends
- Relay Rating: Standard dry contact relay ratings (e.g., 5 A at 250 V AC / 30 V DC)
- Insulation: Industrial-grade PVC or TPE jacket
- Shielding: Braided or foil shielding included
- Operating Temperature: -20 °C to +70 °C
Functional Features:
- Provides galvanic isolation between system and field
- Signal voltage conversion (e.g., 24 V DC logic to dry contact)
- Pre-wired plug-and-play design for quick deployment
- Robust relay for long service life
- Flexible cable for routing in tight spaces
Application Scenarios:
- Connecting DCS digital outputs to third-party control panels
- Interfacing with PLC systems using dry contacts
- Signal inversion or level shifting
- Temporary test and jumper cables for commissioning
Performance Parameters:
- High dielectric strength for isolation
- Reliable contact closure with low resistance
- Durable flex life for moving applications
Material and Structural Characteristics:
- Multi-conductor copper cable
- Reinforced connector backshells
- Molded strain reliefs at connector exits
Working Principle:
The cable carries signals from the source to the relay coil or contacts. The internal relay actuates when the signal is present, opening or closing the contact on the output side. This creates a break in the electrical continuity, isolating the source voltage from the load voltage.
Installation Requirements:
- Route the cable away from high-voltage conductors
- Ensure connectors are fully seated and locked
- Verify the relay coil voltage matches the source signal
Usage Notes:
- Do not exceed the contact rating of the relay
- Check the wiring diagram for the specific contact configuration (NO/NC)
- Inspect the cable jacket for wear if used in high-traffic areas
