General Description:
jieshengda Technology JSD TAmR-1001S series is an input-out four-wire milliohm resistance signal isolation transmitter, which is a small instrument equipment that collects, isolated and amplifiers the resistance of weak and small resistance values and converts them into analog signals, and transmits them to the acquisition card, control room, PLC, PC and DCS system in the form of standard analog signals or user-specified analog signals. The product integrates 2 groups of highly efficient and highly isolated micro power supply, providing isolated working power supply to the input and output, the input, output and working power supply of the product are isolated from each other, the isolation voltage is as high as 3KVDC, the product adopts Kelvin four-wire resistance measurement method, eliminating the measurement error caused by the impedance wire of the wiring and contact resistance, and the internal integration of a high load and high precision Reference constant current source circuit, used to measure the measuring current when the low resistance resistance, to improve the measurement accuracy of the product, the internal circuit response time is fast, the response time is better than 1mS, can replace the four-wire resistance measuring instrument, improve the work efficiency, the product is widely used in mechanical equipment, secondary equipment development, mechanical relay production, instrumentation, impedance measurement test equipment, high precision close connection Plug-in production, precision component measuring equipment and precision connector testing equipment, etc. The isolation transmitter adopts photoelectric isolation technology, has better anti-EMC electromagnetic interference ability, high output precision, small temperature drift characteristics and good linearity, and adopts guide rail installation, easy installation and use
