FM33xx-B110 Thermocouple Fieldbus Modules with EtherCAT interface

FM33xx-B110 | Thermocouple Fieldbus Modules with EtherCAT interface

The module’s circuit can operate thermocouple sensors using a 2-wire connection. Linearisation over the full temperature range is realised with the aid of a microprocessor. The temperature range can be selected freely. The error LEDs indicate a broken wire. Compensation for the cold junction is made through a temperature measurement in the connecting plugs. This means that standard extension leads can be connected. The Fieldbus Modules have back-voltage protection circuitry to protect against external voltages applied to the thermocouple inputs. Voltages of up to 230 V AC are withstood without damage to the module. Those thermocouple inputs that are not affected remain functionally operative or are only affected for a short time.

The extended parameterisation is carried out via EtherCAT. The parameters are stored in the module. The status of the Fieldbus Module is indicated via LEDs.

The different versions of the FM33xx-B110 Fieldbus Module differ in terms of the number of available thermocouple input channels (12 or 32 channels) and the housing type (clip-on housing A or add-on housing B). The add-on housing (type B) features two locking latches and a continuous rubber seal to provide an IP 65 connection to the socket element. In addition, housing type B features two cast brackets with holes for attaching the FM module to mounting plates (through-hole mounting).
