WZPK temperature transmitter is a high cost product from our company, suitable for up to ten types of thermocouple and thermal resistance signal transmission. The product uses a 24-bit Σ-△ analog front end to ensure high precision measurement. Perfect anti-surge and anti-reverse design to avoid misinstallation and misoperation in engineering applications; Enhanced software security design, including low-voltage monitoring reset, multi-task scheduling optimization and other functions. WZPK all use imported components to ensure long service life and stability. In order to facilitate the long-term stocking of large customers, the USB communication cable can be usedfor configuration Settings, and no external power supply is required for setting.

三、接線方式
wiring mode
1號接線柱和2號接線柱分別為24V電源正負(fù)極,線路板帶防反接功能。
The No. 1 terminal and No. 2 terminal are respectively the positive and negative terminals of 24V power supply, and the circuit board has anti-reverse connection function.
The thermal resistance connection supports two wire and three wire. The connection method is shown in the figure above. The solid line is the sensor leadout line, and the dashed line is the short wire, which needs to be connected by the user with a short wire (it can also be short-connected internally according to the customer's needs).
The positive terminal of the thermocouple is connected to terminal 3, and the negative terminal is connected to terminal 4.
