The DELTA IFD8500 is a high-performance, isolated interface converter designed for seamless communication between RS-232 and RS-422/RS-485 networks. Engineered for industrial automation and harsh environments, it ensures signal integrity, noise immunity, and equipment protection.
Key Features
- Full Isolation Protection – 2.5 kV RMS isolation prevents ground loops and protects connected devices from surges and voltage spikes.
- Dual Conversion Modes – Switch-selectable RS-422 or RS-485 operation on the output side.
- Long-Distance Transmission – RS-485/422 supports communication up to 1200 meters (4000 feet).
- High-Speed Data Rates – Supports baud rates up to 115.2 kbps.
- Automatic Data Flow Control – For RS-485 (built-in auto RTS direction control, no programming needed).
- Durable Industrial Design – DIN-rail mountable, compact metal housing for use in control cabinets.
- LED Indicators – Power (PWR) and data transmission (TXD/RXD) status.
