Product Description

General introduction 

GDJB-902 Relay Protection microcomputer test device play a key role in operating electricity power systems reliably and safely. It is the testing device used in professional field of microcomputer protection, relay protection, excitation measurement, fault recorder.


Features

1. Embedded host machine, equipped with big programmed CPLD(Complex Programmable Logic Device).
2. 12channels D/A output simultaneously in a single machine;
3. High precise linear power amplifier, 6phase voltage and 6 phase current output simultaneously.
4. 8inch LCD screen display. Provide with keyboard/mouse connecting port, also 2USB port, 2 RS232 port, to communicate with PC and other communication devices.
5. Easy to carry, suitable for flexible testing and wild working; Intelligent self-protection.
6. 8channels switching value input and 4channels switching value output. Input contact is idle contact and 0-250V potential contact for selectable, intelligent identification.
7. Plentiful Binary and powerful software function.
8. Two groups of DC power supply, 110VDC/1.0A&220VDC/0.6A, no need to set and adjust by software(Optional).
