RSC_02

Introduction
ZEUS presents RSC_02 a very stable and reliable optically isolated RS 485 / RS 422 TO RS 232 converter to be used between PCs and PLCs or any other process control instruments.

RS 232 C RS 485 provides connectivity between any Device that is having RS 485 inter-face with PC, which has RS 232 C interface. It, converts RS 232C signals into RS 485 & Vice versa.

RS 232 C interface is half duplex i.e. it has two common lines for transmission & reception. Thus RS 232 C interface has three wires. The major drawback with RS 232 C interface is that the length of cable is very much limited and baud rate is also very low.

These drawbacks are overcome in RS 485 interface, which is basically two wire / four wire system. The transmit (TXD) as well as received (RXD) both signals use same two lines / separate four lines in differential mode. Due to differential mode the signals can be transmitted over long distances at higher baud rates. Moreover RS 485 also provides point to multi-point connectivity.

RSC_02 is 2 Wire Half duplex convertor

Feature
  1. Optically isolated
  2. 2 Wire mode
  3. can be used on higher boud rate (boud rate selection is required)
  4. RS 232 to RS 485 & RS 422 Operating Modes.
  5. Point to Point / Multidrop and Simplex / Duplex Operating Modes.
  6. Line power source built-in (Cable length No problem).
  7. Din Rail mounting, Compact size

Application
  1. PLCs
  2. Process Automation Plants
  3. Data Equisition Systems
  4. Process Instruments
  5. Moving Display.
  6. Computerize Process Control
