    CMC-141 Multicon Panel Mount Recorder Controller 144x144mm

    The Multicon CMC are powerful and versatile compact-multichannel-controllers with a capability to record data, if the recording function is requested and activated. e.g. 16 RTD ot 31 TC signals. MultiCon CMC-141 is CMC-99's bigger brother. It has all features included in CMC-99, but in addition it has a bigger display, more inputs/outputs and even more logic channels. Casing depth is still only 100 mm. Thanks to that it is one of the first industrial devices which integrates advanced control functions (PID, ON/OFF, time & profiles etc.) and logging of setpoints, excitations and current state of controlled objects. Based on Linux firmware, is stable and the touch screen makes configuration easy and comfortable and data presentation also readable and attractive. Although the Multicon CMC-141 is build in a quite small housing, it can integrate up to 72 inputs, and its construction allows user almost free configuration by choosing up to 3 from 30 available input/output modules. The device can simultanously record all build-in logical channels, and is capable to record data with maximum speed 10Hz (ten samples per second, with some limitation of number of recorded channels). 1.5GB of internal data memory is enough for continuous recording of all channels with a speed of 1 sample per second (each channel) for over 2 months (125 000 000 samples in total!). An operator can download stored data using a USB flash disk or via Ethernet.

FMEDA - SIL assessment

A temperature-sensing device together with a temperature transmitter becomes a temperature sensor assembly. When using FMEDA (Failure Modes, Effects and Diagnostic Analysis) in a SIL verification assessment, also the failure rates and failure modes of the temperature sensing device must be considered. This EXIDA assessment was made for our key transmitter supplier, PRelectronics. In this document typical failure rates for thermocouples and RTD's are stated.
An electrical temperature sensor assembly can be used in a safety instrumented system accordance with IEC 61508 standard. Thermocouple and RTD sensors can be used in conjunction with temperature transmitters, certified for safety relevant applications, such as the PR-electronics transmitters PR5337 / PR6337 / PR7501. Electrical thermometer sensors without a temperature transmitter, for example a resistance thermometer or a thermocouple sensor, is not covered by IEC 61508, since a thermocouple, and a measuring resistor is a simple electrical component, and such component cannot perform any self-diagnostics neither it can detect errors.Typical failure rates for thermocouples and RTD's are listed in the following FMEDA assessment, please click here
