RS-232 to RS-422/485 Converters (with Optical Isolation (C53) (C52E/C53)

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
C52E/C53 converters let you take advantage of RS-422 and RS-485 on systems originally equipped with RS-232. They transparently convert RS-232 signals into RS-422 or RS-485 signals. You do not need to change your PC's hardware or your software. The C52E/C53 let you easily build an industrial grade, long distance communication system with standard PC hardware. They extend the communication distance by 4Kft (1.2Km) or increase the maximum number of connected nodes by 32. The C53 provides the optical isolation for system protection.

Features:
-High efficient converters allow wide range of input voltage(9~36VDC/9~58VDC) and power saving
-Polarity guard available prevents damage from reverse power
connection and provision of over voltage protection
-Rugged metal casing with better mechanical and EMI protection
-35mm DIN rail connection kit option available
-Clear LED indications of power status, RS-232 data signal
status(TX/RX) and operation modes (RS-422/485 4W or RS-485 2W)
-Clear indications of all signals on the casing allow convenient
connection
-Built-in pull high/pull low resistors
-Plug-in screw terminal blocks for easy RS-232, RS-422/485, and power supply wiring
-DIP switch settings for RS-485 2-wire with ERADC auto mode,
-RS-422/485 4-wire mode
-DIP switch setting for internal terminal resistors
-15KV ESD surge protection
-C53 provides CMR-10KV/μs optical isolation between the RS-232 port and RS-422/485 port and 1KVDC isolation between the DC power and the RS-422/485 port
