rdc485ir-dv-3p-cc Repeater

Description

Robust DataComm Isolated RS-485 Repeater, 2- and 4-Wire, DIN-Rail Mount, 9-36 VDC Powered, Fully Isolated, Screw Terminal Connectors On Both Sides.

Isolation, industrial design, small size, DIN rail mount, user indication, and DC supply make the rdc485ir a very engineer-friendly device for your industrial data communication system.

The rdc485ir safely connects 2 and 4-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-ohm internal terminating and bias resistors. 500-watt voltage transient suppressor diodes protect the rdc485ir from normal mode surges, while the full galvanic isolation protects the rdc485ir from common mode surges.
