Product Description

 IRSFC24-B9FSPS - 3KV Opto/Xformer Isolated RS232 toRS485 2 Wire Half Duplex Bidirectional Converter w/ 12V Power Supply & DB9F Adapter w/ 7ft. Cable in Boxed Enclosure.

  • This 3KV Isolated auto transmit unit features Bi-directional serial conversion from RS232 to RS485 in 2 wire half-duplex communications mode.

  • Optimized for Isolated office/indoor/outdoor point to point, or multi-drop systems.

  • Transparent to all asynchronous data, with any combination of data, parity, and stop bits, at data rates up to 115.2Kbps. 

  • Fast auto turn-around, from transmit to receive mode, requires no software delays and eliminates timing problems and data collisions. Jumper J8 can further shorten the turn-around time to accommodate fast responding target devices. We pioneered this leading edge technology long before our competition.

  • The RS485 driver is protected by auto-reset fuses, a transient suppressor bridge, and built-in ESD tolerance. It can drive 32 standard loads at 4000 ft. at data rates up to 115.2 Kbps.

  • Jumpers allow the RS485 termination, two levels of bias resistors, and the RS232 DTE/DCE mode to be user configured. Jumper J7 will place the unit in Loop-Back mode for self test.

  • Edge mounted LEDs display isolated power, and RX and TX data activity at both interfaces. 

  • Pull-up resistors are built-in to accomodate RS232 devices that need inputs: CTS, RTS, and DSR. This unit does not require these, or any other control signals, to operate at maximum performance. 

  • A polarity protected switching power regulator accepts supply voltages from 9 to 35VDC, at 0.5 Watts max. 

  • Broad environmental range. Temperature: -40C to +85C(-40F to +185F). Humidity: 10 to 90% RH(non-condensing)

  • Four(4) easy mount through hole standoffs, which accept #6 hardware, are provided on the circuit board.

  • User connectors are an RJ11/12 telephone style for the RS232, 2 RJ11/12 telephone style and a 3 pin Wago style for the RS485, and a 2 pin screw terminal strip and a 2.1 mm barrel connector for the power. 

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

  • Conformal coating, cables, and connectors, are factory options. Contact us for options help.

  • R E Smith Inc makes a wide variety of isolated converters that address the electrical noise problems that contribute to unreliable communications, and product failure. 

  • We also have a new series of Converters and Repeaters that extend the RS485 communications distance far beyond conventional limits.

  • If what you see here is not exactly what you need, don't hesitate in calling us at 513-874-4796.

  • WARNING: Do NOT connect this device to a telephone system under any circumstances. Damage could result to the circuit board and/or your telephone system.
