Description
Robust DataComm RS-232 3-Port Hub/Repeater w/ DB9 Connector.
The rdc232hub allows connection of three RS-232 devices complete with full 4-port 2.5kv optical/galvanic isolation - including 3 isolated DC supplies. Each port is fully isolated (with floating ground) with reference to the other data ports and the power supply.
The rdc232hub can operate as a full 3-way hub. Any device can freely talk to the other two. Any data received on any port is echoed out the other two. Moving one internal jumper (J3) converts it to a Master/Slave configuration where any data received on port C ("Master") is echoed out both port A and B ("Slaves"). Data received on either port A or B is only echoed out port C ("Master").
500-watt voltage transient suppressor diodes protect the rdc232hub from normal mode surges, while the full galvanic isolation protects the rdc232hub from common mode surges.
Isolation, industrial design, small size, DIN rail mount, user indication, and DC supply make the rdc232hub a very engineer-friendly device for your industrial data communication system.
