Software Functions

          The software with a variety of test functions: can test relays such as voltage relays, current relays, frequency relays, intermediate relays, time relays, impedance relays, differential relays, and microcomputer protection devices such as line protections, bus protections, transformer protections and generator-transformer unit protections.

Feature:

Embedded computer + True color large LCD screen: designed as embedded integration, supports offline operations.

 Selective output modes of the 12 channels D/A(6U+6I) at the same time: can solve the test problems of differential protections, automatic switch and quick switching devices effectively, it also simplifies the test connection and improves the test efficiently.

 Lightweight and portable: total weight of AD661 is less than 15.8 kg.

 Supplied by 220V AC/DC power: the device will alarm if it is connected to 380V AC by mistake.

 The communication between PC and the ONLLY-AD series device is by networkwhich has clear advantages over COM/USB, provides much more convenience for long-distance experiment and improves the efficiency.

 Unique synchronization of multi-machine by power frequency can control multi-machine to output at the same time without any external equipments, can build a test system which has much more and mutual stable analog outputs without any modification. This speciality makes it convenient to do a variety of complicated dynamic simulation experiment, especially meets the needs of institutions such as scientific research organizations, training centers, test and supervision institutions for secondary equipments, teaching bases and electric power departments.

 Embedded GPS receiver (optional) simple and reliable, has clear advantages for testing of pilot protections.

 Transistor binary outputs can be used in high frequency channel test.

 It can offer synchronous outputs with the power frequency.

 The software with a variety of test functions: can test relays such as voltage relays, current relays, frequency relays, intermediate relays, time relays, impedance relays, differential relays, and microcomputer protection devices such as line protections, bus protections, transformer protections and generator-transformer unit protections.

 The software can be updated freely anytime: compatible with all Windows operating system, can be updated freely without any modifying of hardware.
