MM1T12RO
The MM1TI2RO is a 1 channel Thermocouple/RTD input module with
two alarm outputs. The input range can be configured for a range of
reduce effects of electrical noise and mains pickup.
The thermocouple voltage/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 as indicated in the
table below. 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 temperature can be read out of the Modbus registers as a value
between -32767 and 32767 or as a floating point value using the
IEEE754 notation.
The type is setup by writing a value to the Type register (40006). The
value is obtained from the table below. For example to select type K
thermocouples, the value "2" must be written to the TC Type register.
The DIP switch 9 is used to select upscale or downscale burnout. A
value of 32768 is used to indicate upscale burnout and a value of
-32767 is used to indicate downscale burnout.
The module has built in Cold Junction Compensation. Use must be
made of the correct thermocouple extension wire to avoid reading
errors.
The thermocouple module can also be configured for a 0 - 50mV
input range. The TC Type register must be set to 9 for this option.
The value in the register which is read back over the network is 0 -
50,00.
The temperature can be offset by writing an offset value to register
40009. The temperature is filtered to prevent false alarms
operations. The filter parameters can also be configured by
writing to Modbus registers.
The alarms operate from the temperature value. A number of alarm
modes can be configured depending on the application. Alarm
setpoints, hysteresis and delays are configured by writing to the
Modbus registers.
The alarms can also be operated manually by controlling the
Modbus registers over the network.e inputs to be read as either
single bits or all at once as a single register on the Modbus network.
