IRSFC24FB 3 KV Opto/Xformer Isolated RS232<=>RS485 2 Wire Half Duplex Converter

Product Description

IRSFC24FB-BSPS as converter - 3 KV Opto/Xformer Isolated RS232 to RS485 2 Wire Half Duplex Bidirectional Converter w/ 12V Power Supply in Boxed Enclosure

This 3KV Isolated auto transmit unit will be factory configured as a bi-directional serial converter, or repeater, 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. We pioneered and perfected this leading edge technology long before our competition.
The isolated RS485 transceiver 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.
When configured as a repeater, the unisolated RS485 transceiver is protected by its built-in ESD tolerance. This side of the unit is intended to be connected to the system by a short cable run.
A jumper allows removal of the RS485 termination, and several jumpers enable multiple levels of bias in order to optimize performance in less than ideal system configurations.
Edge mounted LEDs display regulated power, and RX and TX data activity.
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 3 pin removable terminal strips for the isolated RS485, and the unisolated RS485/RS232, and a 2 pin screw terminal strip for the power.
Accessories available are a 12VDC Switching Power Supply(Wall Wart), and an enclosure. No cables are available for this unit
Conformal coating, 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.
R E Smith Inc has similar converters with comparable/enhanced performance. They feature different connectors, LEDs, and termination options. Check out the IRSFC24, IRSFC24H, and IRS422HV.
We also have a new series of Converters and Repeaters that extend the RS485 communications distance far beyond conventional limits.
