IRS422HV-BSPS - RS232 to RS485 / RS232 to RS422 Bidirectional Converter

IRS422HV - 3 KV Opto/Xformer Isolated RS232 to RS485 (2-wire half duplex) / RS232 to RS422 (4-wire full duplex) Bidirectional Converter with 12V Power Supply in Boxed Enclosure.

• This versatile unit features 3KV isolated bi-directional serial conversion from RS232 to RS422 (point to point 4 wire full-duplex) or from RS232 to RS485 (2 wire multi-drop half-duplex).

• The RS422 / RS485 driver allows 32 standard loads at 4000 ft. and data rates up to 115.2 Kbps.

• The RS422 / RS485 transceiver feature built in static protection, transient suppression and is coupled to the field wiring through auto reset communications fuses.

• An additional layer of 3KV galvanic isolation helps protect the unit from 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.

• When configured in RS485 mode, it features fast auto turn-around from transmit to receive mode, requires no software delays and eliminates timing problems and data collisions.

• This unit provides edge mounted power and data activity LEDs for both the RS232 and RS422 / RS485 ports.

• A polarity protected efficient switching power regulator accepts supply voltages from 9 to 35 VDC (0.5 Watts max.).

• Jumpers allow the RS422 / RS485 termination and bias resistors, and the RS232 DTE/DCE mode to be user configured.

• The user connections are a 5 pin screw terminal strip (RS232 and power), and a 6 pin screw terminal strip (RS422 / RS485).

• 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.

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

• Accessories available are a 12VDC Switching Power Supply (Wall Wart).

• Can be easily reconfigured as a TTL/CMOS to RS422/RS485 isolated converter.

• R E Smith Inc. makes a variety of isolated converters that address the electrical noise problems that contribute to unreliable communications, and product failure. (Call us: 513-874-4796)
