Description
The ET-7018Z/PET-7018Z is an ethernet based data acquisition module specifically designed for extremely accurate thermocouple measurement and features automatic cold-junction compensation for each channel to ensure temperature output consistency and stable temperature output in the field. Current input and voltage input are both supported. Another feature is that its ten input channels can be individually configured for different kinds of analog input. Open thermocouple detection and ESD/EFT/Surge protection mechanisms are also included. The six digital output channels can be set as alarm outputs with short-circuit protection and overload protection.
NOTE: Comes with DB-1820 Screw Terminal Connector
Configuration of the module is done via its integrated Web Server, while communication to a Data Logging / SCADA Package can be achieved using the ModbusTCP protocol.
The PET-7018Z is a Power-over-Ethernet version, for use with a compatible Ethernet Switch. Please call us about this unit.
