While SFT2885 is used to create the logic, it works in tandem with , the general setting and operating tool for Sepam relays. The typical workflow involves: Designing the logic in SFT2885 . Validating the program through simulation.
is a high-frequency, low-noise, gain-block amplifier integrated circuit (IC) widely used in RF and microwave communication systems. Manufactured originally by RF Micro Devices (RFMD) — now part of Qorvo — this device has become a staple in applications requiring wide bandwidth, stable gain, and moderate output power. Its combination of performance, ease of use, and reliability makes it a popular choice among RF design engineers for both commercial and industrial systems.

Because the SFT2885 has ~15 dB gain and good return losses, two or three can be cascaded for 30–45 dB total gain. Between stages:
for programming and customizing control system functions within the Sepam series 80 While SFT2885 is used to create the logic,
In many legacy and modern hybrid substations, protection relays output analog signals or dry contact signals. However, modern communication networks operate on digital protocols (like IEC 61850). The SFT2885 serves as the translator and guardian between these two realms.
Technical manuals and introductory examples, such as creating a Set/Reset example, are available through the Schneider Electric Knowledge Base. Logipam (SFT2885) Manual for Sepam Series 80 : A built-in tool that allows users to
