[0002] At present, the wiring terminals used for remote signal and telemetering signal collection on the market are all independent terminals. In addition, the telemetering collection terminals have no signal conversion method and cannot achieve small current (such as 4-20mA) or small voltage (0-5V) output. For the general measurement and control device DC board (current type: 4-20mA, voltage type: 0-5V), the signal quantity collected by telemetering (generally the secondary voltage of the voltage transformer or the secondary current of the current transformer) cannot be directly connected to the measurement and control device DC board.

[0003] The problem this leads to is that if the existing technology collects analog quantities of a certain telesignaling circuit, it can be achieved by using an independent DC transmitter, etc., but there are many problems as follows: one DC transmitter is required for each collection object, which greatly increases the cost; the reliability of the DC transmitter operation and the maintenance workload increase; on-site installation is difficult, etc. Summary of the invention
