These modems convert digital information to FSK analog signal and vice versa. The application of FSK modems is to transfer information from remote terminals (RTU) to dispatching centers. Modje Niroo modems are type tested by EPIL reference laboratory.
Types of Modje Niroo FSK modems:
: MNK5D* This modem is internal and modular with a transfer rate of 600 and 1200 bits per second, which supports full duplex mode. The method of sending and receiving information is synchronous, and it is designed and produced as a direct replacement for the NSK5 modem made by ABB and installed inside the corresponding sub rack.
MNK6*:
This series of SCADA modems is designed and produced in 2 models: MNK6E, External (Rail-Mount) and MNK6I, Internal (Rack-Mount). Among the salient features of this series, the following can be mentioned:
– Operation based on microprocessor and microcontroller
– Adjusting the level of the transmitted signal: dBm +8 to -8 dBm levels with 2 dBm steps
– Data transfer rate: 600 and 1200 bits per second
– Working mode: Full Duplex
– Data transfer method: serial/asynchronous
MNC-23WT25*
This model can be used directly in the ABB RTU560 terminal sub rack and is a direct replacement for the ABB 23WT25 model.
