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. The SCP converters are tough, compact (3.9- x .9- x 2.9-in.), and versatile. All models come with built in switchable bias and termination, a 2-position removable terminal block for easy wiring, and bit-wise enabled circuitry to detect character time-out--eliminating the need to set DIP switches for the baud rate.
The basic model, SCP211-DFTB3, is non-isolated and made for less demanding temperature extremes. Model SCP211T-DFTB3 provides a wider operating temperature and is non-isolated. These models should be used when isolation is not required, such as applications in which the data line does not exit the control cabinet. Model SCP311T-DFTB3 offers 2 kV Isolation and will stand up to -40 to 80° C temperature variations. The rugged SCP311 is designed to protect expensive control equipment.
