DY-400S Touch Screen Switch

【 Product Introduction 】

DY-400S touch screen low potential conversion switch, mainly used for standard thermocouple and standard platinum resistance, working thermocouple and thermal resistance, DC small signal in the measurement of conversion, through manual operation or standard interface control can be any one of the switch to the output, the switch contact has a very low thermoelectric potential (less than 0.2 microvolts). Easy to operate, it is an indispensable important equipment for automatic verification (with RS485 communication interface), calibration and measurement system.

【 Main purpose 】

Used for temperature field and laboratory verification, calibration or testing, supporting manual thermal resistance, thermocouple verification system. Any input channel can be used to verify standard resistance, standard galvanic couple, standard platinum resistance thermometer, industrial platinum thermal resistance, industrial copper thermal resistance, thermocouple and various auxiliary instruments of the subject.

【 Mode of operation 】

Switch channels by manual switching or communication control.

When measuring thermal resistance, three wire system measurement, four wire system measurement, can be received to switch, no secondary wiring.

This is a communication interface model (485 communication), supporting the host computer software/digital multimeter or our thermal automatic verification system master box, can be upgraded to automatic scanning. Realize desktop plane connection, intuitive and easy to operate.
