OPTO-ISOLATORS
Protect your high-speed equipment data from ground-loop problems.
Features
Fiber optic circuitry. Stops groundpotential differences 2500 volts. Small lightweight. Choose from models RS-232 RS-422/ RS-485 protection. Data rates 19.2 115.2 kbps. Optional power supply available RS-232 models. 4-wire versions RS-422/RS-485 isolator available. Transparent operation.
uard your asynchronous data equipment from ground loops between buildings with BLACK Opto-Isolators. ground loop occurs when ground potential different each cable. These often occur from floor another, from building another, anywhere there's widely spaced sites that have different earth-grounding systems characteristics dissimilar electrical demands. difference potential causes dangerous currents that your equipment. OptoIsolator, however, stops those currents dead-they simply can't across optical barrier. keeps difference ground potential each data link from interfering with data integrity damaging attached
equipment. device does this creating electrical circuits (where otherwise there would have been only one) separating these circuits with "air gap" that electrical energy can't cross, RS-232, RS-422, RS-485 signals-translated into pulses light-can. Each model featured here provides 2500 volts optical isolation between device point-to-point setup. Because it's small (less than inches high) lightweight less than pound), won`t your way. SP340A-R3, SP400A-R3 RS-232 serial equipment that's running high rate speed 115.2 kbps), High-Speed Opto-Isolator (SP340A-R3). your RS-232 equipment runs lower speed
19.2 kbps), Opto-Isolator (SP400A-R3). Both models plug directly into connect short cable. devices isolate four RS-232 signals. addition data line signals RD), RS-232 Opto-Isolators pass user-configurable control signal each direction. These isolation capabilities make devices perfect hardware flow control. isolators come equipped with 8-position switches. These easy-to-access switches enable configure user-configurable leads device work wide range applications. Designed operate transparently, Opto-Isolators begin operating soon they

receive power. They usually require external power supply operation because they draw their power from RS-232 interface. interface doesn`t give enough power, optional power supply: 9-VDC Power Supply (PS1002). This 120-VAC, 60-Hz power supply unit used provide secondary voltage isolators. You'll also need optional power supply with SP340A-R3 SP400A-R3 want achieve protection against ground loops equipment separated greater distances. SP401A, SP402A SP401A SP402A OptoIsolators protect against ground loops between equipment with
RS-422/485 interfaces, isolating four signals (XMT+, XMT-, RCV+, RCV-) process. Both support async data rates 115.2 kbps draw their power from external wallmount transformer. Opto-Isolator (SP402A) differs from SP401A that 4-screw terminal block with strain relief instead RJ-45 jack each side and, therefore, does support 2-wire operation. with RS-232 isolators, RS-422/RS-485 models have switches configuration purposes.
