ICSX7HV: 3KV Isolated Serial 7 Port RS485 Repeater with RS232 Converter Port


"Let me spin a very large
RS485 network for you!"

  • This auto transmit unit features 7 isolated(3KV) RS485 ports in 2 wire half-duplex communications mode and 1 RS232 port

  • As a true repeater, data received on any one port is transmitted to all other ports. Thus each port becomes the the start of an isolated and buffered "star configuration" branch, expanding the network while observing the RS485 loading rules

  • Robust RS485 drivers, with built in transient suppression, allow 32 single unit loads at 4000 ft. and data rates up to 115.2 Kbps on each port

  • Galvanic Isolation of 3KV helps protect against destructive transients often found in industrial and outdoor environments

  • Transparent to all asynchronous data, with any combination of data, parity, and stop bits at data rates up to 115.2Kbps. Contact factory for faster speed enhancements

  • Fast auto turn-around, from transmit to receive mode, requires no software delays and eliminates timing problems and data collisions

  • Edge mounted LED Indicators for power and data on all ports

  • Efficient onboard polarity protected power regulators accepts supply voltages from 9 to 35 VDC, at 3 Watts max

  • Jumpers allow the RS485 termination resistors, the RS485 Rx and Tx enables, and the RS232 DTE/DCE mode to be user configured. The 7 isolated RS485 ports can be reconfigured as several independent repeaters

  • The user connections are: 3 pin removable terminal strips(RS485), a 2 pin terminal strip and 2.1 mm barrel connector(power), and an RJ11/12(RS232)

  • The RS232 converter port provides an interface to a computer or host controller. When used as a converter this port transmits and receives serial data through all the isolated RS485 ports

  • Broad environmental range. Temperature: -40C to +85C(-40F to +185F). Humidity: 0 to 95% RH(non-condensing)

  • Six(6) easy mount through hole standoffs, which accept #6 hardware, are provided on the circuit board.

  • Conformal Coating Available (Call us: 513-874-4796)

  • Accessories available are a 12VDC Switching Power Supply(Wall Wart), and a 7ft DB9F to RJ11/12 RS232 cable.

  • We also make similar isolated multi-repeaters in 5 Port(IBS485HV), and 10 Port(ICS485HV) versions.

General Description:

This unit can be connected to a computers' RS232 port, and distribute RS485 via 7 Isolated Ports to form large/robust networks. Units can be cascaded for very large RS485 multi-drop (2-wire, half-duplex) networks.

Need something special? Please contact us. We have additional isolated and non-isolated converters, repeaters, and repeater hubs. Units are generally stock to 2-3 business days for shipment. We design and manufacturer our entire product line, and offer technical support for our units, and can offer system recommendations for your application. Please give us a call: 513-874-4796
