RS-422/485 Isolated Repeaters - ULI-234 Series

The series feature 2 kV isolation on data lines and terminal blocks for RS-422/485 2 or 4-wire modes and can add 32 nodes to an RS-485 network.

ADAM-4510

The ADAM-4510 repeaters simply amplify, or boost, existing RS-485 signals to enable them to cover longer distances. They extend the communication distance by 4000 ft (1200 m) or extend the number of connected nodes by 32.
ADAM-4510I

The ADAM-4510I (RS-422/485 repeater) is designed more rugged than previous models which have wider operating and storage temperatures, can accept a wider power input, and have excellent anti-noise design. Moreover, it provides signal isolation (3,000VDC) protection and power surge (50V) protection. These industrial-grade features ensure robust and reliable operation in harsh environment applications.
ADAM-4510S

Most industrial computer systems come with standard RS-232 serial ports. Though widely accepted, RS-232 has limited transmission speed, range, and networking capabilities. The RS-422 and RS-485 standards overcome these limitations by using differential voltage lines for data and control signals. The ADAM-4520/4522 converter lets you take advantage of RS-422 and RS-485 on systems originally equipped with RS-232. It transparently converts RS-232 signals into isolated RS-422 or RS-485 signals. You do not need to change your PC's hardware or your software. The ADAM-4510S repeater simply amplifies, or boosts, existing RS-422/485 signals to enable them to cover longer distances. It extends the communication distance by 4000 ft. (1200 m) or increases the maximum number of connected nodes by 32.
BB-485OP

Model 485OP is an optically isolated RS-422/485 signal repeater. In addition to 2KV isolation on the data lines, it can be used to extend RS-422/485 circuits an additional 1.2 km (4,000 ft.), thereby doubling the range. An added benefit is the ability to add another 32 nodes to an RS-485 network and join 2 and 4 wire systems. The compact design fits almost anywhere. Terminal blocks allow easy installation. Wiring schematic on the label eliminates guesswork. A 12 VDC power supply is required, and included, with blades for USA, EU, UK, AU, UP & CN.
BB-485OPDR

Model BB-485OPDR, RS-422/485 line repeater, provides isolation and surge suppression. The repeater extends an existing network an additional 1.2 km and expands it beyond the 32 node limitation. Data signals and power inputs connect via terminal block. Automatic Send Data Control (no SW drivers).
BB-485OPDR-HS

Model BB-485OPDR-HS is a high speed, optically isolated RS-422/485 repeater that supports data rates up to 1.5 Mbps. Isolation - Model BB-485OPDR-HS provides 2 kV digital isolation with 8 kV air ESD protection and 600 W transient voltage suppression on the data lines. Range Extension - Model BB-485OPDR-HS can be used to extend the range of a network up to 1.2 km (4000 ft), depending on data rates, and to add additional nodes. 2-wire RS-485, 4-wire RS-485 and RS-422 are supported. Data signals and the power inputs connect to built-in terminal blocks. Power - The repeater operates on externally sourced 10 to 30 VDC power (power supply is required, not included, sold separately). Enclosure - The enclosure has a DIN rail mount enclosure that is designed to easily fit on standard 35mm DIN rail.
BB-485OPDRI

Model BB-485OPDRI isolated RS-422/485 repeater is designed for rugged industrial environments. It is UL listed and certified for use in Class 1/Division 2 locations. Powerful optical isolation on both data ports protects your equipment and data from damaging ground loops and surges. Additional isolation on the power supply circuits adds a third degree of protection. Packaged in a rugged ABS plastic case, this repeater operates in wide temperature extremes. With a 35mm DIN rail mounting bracket, it easily integrates into control panels or other industrial equipment. Installation and configuration is easy with DIP switches to set up baud rate and serial communications mode. Removable terminal blocks make wiring a snap. Power is connected through separate terminal block that accepts 10 to 48 VDC from any external source (power supply required, not included, sold separately).

BB-485OPDRI-PH

Model BB-485OPDRI-PH is a premium, heavy industrial RS-422/485 isolated repeater. Designed for rugged industrial environments, it meets some of the most exacting compliance tests in the industry. IEC 61850-3 and IEEE 1613 rated, it is suitable for installation in electrical substations. (These specifications are more stringent than NEMA TS1/TS2 requirements for transportation applications). Powerful isolation on both data ports protects your equipment and data from damaging ground loops and surges. Additional isolation on the power supply circuits adds a third degree of protection. Packaged in a rugged IP30 metal case, it extends full or half-duplex RS-422/485 signals an additional 4000 feet and allows you to add another 32 nodes to your network. Bit-wise enabled circuitry automatically detects the data rate without setting a DIP switch. 10-48 VDC power is externally sourced (power supply required, not included, sold separately).
