Special sales item with limited quantities available. If you are interested in ordering multiple items, please contact us to verify inventory.

The rdc485ir3 safely connects 2-wire RS-485 devices and networks together without danger of ground loops and damaging surges. It also doubles permitted cable length. Data signals have 2.5Kv optical isolation. Isolated DC supplies provide full 3-port galvanic isolation. The signal (reference) ground for both RS-485 ports float with respect to power supply ground. The biased network principle is used for bi-directional communications without control signals. Jumpers enable 120? internal terminating and bias resistors. 500 watt voltage transient suppressor diodes protect the rdc485ir3 from normal mode surges, while the full galvanic isolation protects the rdc485ir3 from common mode surges.

Isolation, industrial design, small size, DIN rail mount, user indication, and DC supply make the rdc485ir3 a very engineer-friendly device for your industrial data communication system.
