Heavy Industrial RS-232 to BB-485DRCI-PH RS-422/485 Isolated Converter Features Converts RS-232 data signals to RS-422/RS-485 2 KV 3-way isolation (input/output/power) Data rate: 1.2 to 115.2 Kbps Wide operating temperature: -40 to +85 C Rugged IP30 metal panel mount case 10-48 Vdc power (external power supply required, sold separately) UL Class 1/Division 2 Introduction Ordering Information Model BB-485DRCI-PH is a premium, heavy industrial RS-232 to RS-422/485 isolated Model No. Description converter. Designed for rugged industrial environments, it has been put through some of the most exacting compliance tests in the industry. Meeting the requirements of IEC 61850-3 BB-485DRCI-PH Heavy Industrial RS-232 to RS-422/485 Isolated Converter and IEEE 1613, it is suitable for installation in electrical substations. These specifications are more stringent than the NEMA TS1/TS2 requirements for transportation applications. Powerful isolation on both data ports protects equipment and data from damaging ground Accessories Sold Separately loops and surges. Additional isolation on the power supply circuits adds a third degree of BB-MDR-40-24 Power Supply, 24 Vdc, 1.7 A output power, DIN rail mount protection. An external power supply is required (not included, sold separately). BB-TBKT1 Replacement terminal block, 2-position, 5.08mm, 8A, 300V Packaged in a rugged IP30 metal case, it converts unbalanced, full or half-duplex RS-232 BB-TBKT2 Replacement terminal block, 5-position, 5.08mm, 8A, 300V signals to balanced RS-422/485 signals. Featuring Automatic Send Data Control circuitry, it does not require special software control of handshake signals in RS-485 mode. Bit-wise enabled circuitry automatically detects the data rate without setting a DIP switch. All product specifications are subject to change without notice.
