More Description

Model SCP311T-DFTB3 serial converter is compact and rugged, designed and tested to meet heavy industrial EMC standards. The RS-232 signal is connected through a female DB9 connector. The RS-422/485 (2-wire and 4-wire) signal is connected through a removable terminal block, making wiring easy. Power is connected through a two-position, removable terminal block. A 10-30VDC external power source is required (not included, sold separately). Bit-wise enabled circuitry automatically detects the character time-out eliminating the need to set DIP switches for the baud rate.Model SCP311T-DFTB3 offers 2 kV isolation plus a -40 to 80°C wide operating temperature. This rugged model is an excellent investment for protecting your expensive control equipment.
