Abstract
The utility model discloses a signal isolator which relates to industrial automation instrumentation and is especially suitable for monitoring, converting, isolating and outputting the signals of a DCS system, such as temperature, pressure, flow, etc. The signal isolator comprises a mainboard, a switching power supply, a signal input end, a signal conversion part, a signal isolation part, a CPU, a memory and a signal output module. The utility model is characterized in that the mainboard comprises two sets of output module slots which can insert and draw the signal output module to switch the output function. The utility model has the advantages that a three-way input, output and power supply optical-electrical isolation program is adopted, the I / O ports of the CPU are reasonably distributed, the action of each function pin of the CPU is switched by parameter modifying, and the output module slot of the mainboard in which the output function module is inserted is replaced, so that the conversion of different output functions can be achieved.
Description
Technical field:
The utility model relates to industrial automation instrument, and output is isolated in the monitoring conversion that is specially adapted to the signals such as temperature, pressure, flow of DCS system.
Background technology:
Present isolator mainly comprises: power unit, signals collecting part, central processing unit, photoelectricity isolated part, segment signal output; Its function can realize input, output, power supply is tripartite isolates, can adapt to present various DCS system configurations uses, because existing system runs into process modifications often, change primary instrument, and unit such as actuator, make that the isolator of function singleness can't be competent at changeable system originally, the isolator that system personnel often needs frequently to change difference in functionality could use, not only increase cost, also delay the duration, signal isolator reasonable distribution central processing unit I/O mouth of the present utility model, each function mouth function is switched software by revising parameter, changes the output module slot that the output function module is inserted its mainboard simultaneously, can realize can not output function conversion, greatly reduce system cost, made things convenient for the flexible and changeable property of system.
The utility model content:
The purpose of this utility model is in order to overcome above defective, and a kind of signal isolator that can online switching output function is provided.
Its scheme is: signal isolator comprises: mainboard, Switching Power Supply, signal input part, conversion of signals part, Signal Spacing part, central processing unit, storer, signal output module;
It is characterized in that: Switching Power Supply partly comprises safety electric capacity, inductance, rectification silicon stack, anti-low-and high-frequency electric capacity, switching tube, optocoupler, transformer, is positioned at the mainboard right side; Signal input part connects conversion of signals part, Signal Spacing part, central processing unit successively, and storer is connected with central processing unit, and signal output module links to each other with the I/O mouth of central processing unit by the output module slot; Mainboard includes two groups of output module slots, can plug signal output module and switch output function.
Its advantage is to have adopted input, output, the tripartite photoelectricity isolation scheme of power supply, the fine signal anti-interference problem that solved, reasonable distribution central processing unit I/O mouth, switch the effect of each function pin of central processing unit by revising parameter, and replacing output function module is inserted the output module slot of its mainboard, can realize the conversion of different output functions, greatly reduce system cost, make things convenient for the flexible and changeable property of system.
Description of drawings: accompanying drawing is a block diagram of the present utility model.
