New Low Cost DIN-Rail Dual Port Signal-Powered RS-232 Line Driver
Dataforth Corporation, Tucson, Arizona announces the introduction of its new,
high performance DCP35 DIN-rail signal-powered RS-232 line driver. The new device
offers customers a unique combination of protection, speed, and versatility for
DIN-rail mount industrial data communication applications.
The DCP35 signal-powered line driver
allows computers, controllers, terminals, and other industrial I/O devices with
RS-232 ports to communicate with each other over extended distances while protecting
valuable equipment and signals from damage or degradation due to ground loops,
power surges, lightning strikes, and other electrical hazards commonly found in
industrial environments.

The
new DCP35 uses heavy-duty optical couplers to provide 300Vrms continuous (500VDC
surge, 1 minute) isolation between input and output signals. The dual port models
offer inter-channel isolation of 1500Vrms continuous (5000VDC surge, 1 minute).
For added safety, ANSI/IEEE C37.90.1-1989 surge protection is also provided on
all field side connections.
The
DCP35 does not require a power supply for operation. The use of low power circuits
and a sensitive optically isolated receiver allow the unit to derive all necessary
power from the RS-232 data and control signals. It is designed for full-duplex,
asynchronous operation over two DC-continuous, non-loaded, twisted-wire pair.
It can be operated up to 19.2K bps (Baud) at a distance of 0.5 miles (0.8 km).
The
DCP35 is easy to set up and to use. Markings on the exterior of the compact, DIN-rail-mountable
package (4.2" x 3.3" x 0.89"; 107mm x 84mm x 22.5mm) provide all the information
necessary to quickly wire and set up the device. Each unit features a convenient
DCE (Data Communication Equipment) to DTE (Data Terminal Equipment) switch that
reverses pins 2 and 3 of the RS-232 connector. For installation and system troubleshooting,
each unit has diagnostic LEDs on the transmit and receive lines. RS-232 connections
may be made through male or female EIA 9-pin D-sub connectors. Field connections
are made through pluggable screw terminal connectors. The device operates over
a temperature range of 0 to +70°C.
The
device is available in single and dual channel versions.
The
new device adds to the Company's already extensive line of high performance industrial
data communications products and systems, including stand-alone and rack-mounted
limited distance line drivers and line driver systems. Dataforth Corporation is
a worldwide leader in the design and manufacture of signal conditioning and data
communications products for industrial and institutional markets.
