DDC2I

The DDC2I is a DIN railmounted optically isolatedRS -232 to RS -422/485converter. It is especiallydes igned for use withModicon PLCs and Niobraracommunication modulesequipped with RJ-45 RS-232ports.

The DDC2I's RS-232 port hasan RJ-45 connector designedto use straight through cablingfrom the RJ-45 RS-232 port ofa Modicon Micro PLC, TSXMomentum™ PLC, TSX Compact PLC, NOM 252 or NR&D . A variety ofserial cables are available from Niobrara to allow the DDC2I to be used with otherstandard RS-232 ports.

The DDC2I has two RS-422/485 connectors to increase flexibility. A DB9 connectorhas the standard SY/MAX pinout for use with Square D SY/MAX devices and standardSY/MAX cabling. The other connector is a removable screw terminal that is wired inparallel to the DB9 connector for use with POWERLOGIC equipment or other RS-422/485 devices.

The DDC2I supports 4-wire RS-422, 4-wire RS-485 multidrop or 2-wire RS-485multidrop networks. It contains terminating and biasing resistors that can be disabledand can run in Master or Slave mode. Multidrop operation is controlled by the RS-232RTS pin.

Applications:

Power:

The DDC2I enables the user to:

Build a serial network of Modicon PLCs

Use a Modicon PLC as the master of a Modbus RS-485 multidrop network

Use a Niobrara QUCM-S to communicate with a network of RS-485 devices

Run RS-232 signals further than 50 feet

Many Modicon-style RJ-45 RS-232 ports, such as those of the Modicon Micro PLC, TSXCompact PLC and the NR&D QUCM-S supply 5VDC power to the DDC2I. Forinstallations using other equipment the DDC2I must be powered by 9 to 24 VDCthrough a removable screw terminal power connection. A Niobrara TR92 wall-mounttransformer is provided with the unit for this purpose. If suitable power is alreadyavailable, the DDC2I may be obtained without the transformer at a reduced cost (orderpart number DDC2I-NT). Consult the current price list for pricing information.

The DDC2I comes with both a 5-position removable screw terminal RS-422/485connector and a 2-position removable screw terminal power connector. The DDC2Ihas a one year warranty; see Niobrara's Standard Terms and Conditions of Sale fordetails.
