Modbus to Profibus Converter
P485
-
The P485 Modbus to Profibus Converter acts as a gateway between a Modbus RTU network and a Profibus-DP network. Integration of Modbus devices into Profibus networks is enabled without loss of functionality, control, and reliability, both when retrofitting to existing equipment as well as when setting up new installations. The P485 Modbus to Profibus Converter is an external DIN-rail mounted device which provides Profibus network connectivity to Modbus devices via a serial RS232/RS422/RS485 interface.

Modbus RTU Analog Input Modules
-
The Datexel range of Modbus RTU analog input cards for both RS485 and RS232 with Modbus or ASCII protocol can be combined with the DAT9000 series of Modbus Masters. A choice of input cards or modules are available and have various optional inputs such as Voltage, Current, Thermocouples, RTD, and Resistance. Also a choice of 2, 4, 8 channel options are available. The DAT3011 is a Modbus RTU Slave with 1 selectable universal input (Thermocouples, RTD, mV, RTD's or Resistance), 2 x 4-20mA or 0-10V input and 2 x4-20mA outputs. The DAT3011 also has 3 digital inputs and 3 relay outputs. Each module is isolated from each other and is set up using the DAT3000 software Development package which is free of charge from the Datexel download web page. Datexel also has universal input modules. An 8 channel analog input card is available making the DAT3000 series a very economical solution to large and small scale Data Acquisition. Combining these analog input cards with the analog output cards, the digital input/output cards and the communication devices make Datexel the smart choice where Data Acquisition is required.

T7
-
The T7 is available in several interface and protocol options. The physical interface can be RS232, RS485 or US Digital's CAN (Controller Area Network). The protocol can be either US Digital's serial protocol or Modbus RTU. The RS232 version supports a single T7 with up to 100 ft of cable. For users that need longer cable lengths or multiple T7s on a single bus, the RS485 or US Digital CAN (Controller Area Network) version can be used. The USD-CAN protocol allows a network of up to sixty-four T7s to be connected to a single host. Power for each T7 is supplied over the CAN network cable. The host accesses the USD-CAN T7s through US Digital's low cost CANA-232/CANA-485 adapter module. This module allows the host to access each T7 on the network using simple, easy serial port commands, just like the RS232 version. The RS485 version supports up to 32 T7s on the bus.
