MMTCP6RTD - RTD INPUTS

The MMTCP6RTD module is a 6 RTD input module. The module can accommodate either 2 or 3 wire RTD sensors. The RTD inputs are isolated from the logic. 

The RTD resistance is read by the module circuitry, linearised and converted to degrees Centigrade. No ranging is required as the module covers the full range of the RTD. The value that is read from the Modbus register is the actual temperature in degrees centigrade to 0.1°C resolution. ie: a value of 3451 corresponds to a temperature of 345.1°C. 

The RTD type is setup by writing a value to the RTD Type register . The value is obtained from the table below. For example to select a PT100 RTD, the value "1" must be written to the RTD Type register. All 6 RTD inputs adopt the same RTD type. 

A value of  -32767 is used to indicate downscale burnout.

Note: As there is no inter-channel isolation, isolated RTD's must be used in order to prevent ground loops and reading errors. 

Each MMTCP6RTD Module has a unique Ethernet IP address which must be programmed into the PC or PLC. The IP address in the MMTCP6RTD Module is configured via the Web Server. Any standard Web browser such as Internet Explorer can be used to access the web pages were configuration is carried out. The converters are factory programmed with a default IP address of 169.254.111.111. This address must be changed before the converter is added to an existing network. 

The web page address for viewing the RTD input parameters is http://169.254.111.111/index.htm  and the address for viewing the configuration is http://169.254.111.111/tconfig.htm.
