Description
Technical field
The utility model relates to a kind of miniaturization current acquisition modules.
Background technique
Existing power monitoring circuit, protective relay, instrument and control system can all need in data collection system etc.
External current signal is acquired, and is converted to bus mode or serial mode is transferred to control equipment, controls equipment needle
Logic control is carried out again to the data after conversion, board size is big, occupies the device space, and circuit is complicated, and at high cost, maintenance is tired
Difficulty etc. devises the current acquisition general module of modularized design thus, and area occupied is small, for finding that indicating equipment is exhausted in time
The bad state of edge protects operator's personal safety.
Utility model content
In order to solve the above technical problems, the utility model provides a kind of miniaturization current acquisition module.
The utility model is achieved by the following technical programs.
A kind of miniaturization current acquisition module provided by the utility model, including printed circuit board, interface connector, screw
Fixedly connected hole, electronic component；The screw is fixedly connected with hole machined on the quadrangle of printed circuit board, the interface connection
Device is arranged on the side of screw fixedly connected hole, in the circuit of the electronic component grafting on a printed circuit board.
