This item is known as a Universal Amulet, or a Magic Square Token, depending on which school you went to.
The symbols on the outside are a septagram of the planets. Skipping the Star of David on the top and moving clockwise, the first symbol is Saturn, then Jupiter, Mars, the Sun, Venus, Mercury, and the Moon. The order seems unusual, but it is traditional in how septagrams are set up. If you trace them in a specific order (Sun, Moon, Mars, Mercury, Jupiter, Venus, Saturn), they make a pattern of the days of the week, starting with Sunday. Reverse that pattern, and you get the Sephiroth of the Tree of Life.
The square with numbers in it is the Kamea of Saturn. Kamea are Hebrew magical squares traditionally associated with the Qabalah and the planetary Sephirah on the Tree of Life. This one represents the third Sephirah. Each row, column and diagonal is equal to 15. The sum of all numbers is 45, or ‘Mah’, the secret name for Yetzirah, the World of Formation.
The third Sephirah is Shabbathai, the Sphere of Saturn, also the planetary symbol to the right of the Star of David, and therefore the most important for this talisman. Shabbathai brings wisdom, which may be the purpose of the talisman.
The symbols below and to the right of the magic square appear to be angelic scripts. If pressed to guess, the one below looks very much like the script for the angel Camael, and the one to the right is like that of Caffiel (according to Barrett's ‘The Magus’). Camael is chief of the order of powers and one of the Sefiroth according to the Qabalah. In Clement's ‘Angels in Art’, Chamuel (a variation on the spelling of the same angel) was the angel who wrestled with Jacob. Caffiel is the archangel ruling over Saturday.
Above the magic square is a symbol which invokes the magic of the talisman. At the top, it has the name of the angel Aba, the angelic luminary invoked in Qabalistic rites. I'm not certain what the other names (ELAB, EHIE, TAIE) are meant to do. Nor am I certain what the numbers to the left of the magic square are meant for.
Likely it is a mystical Hebrew talisman for bringing wisdom, although just as likely a protective talisman (since most talismans are meant for protection).
The numbers 5.25.65.325 are all specifically related to Mars and therefore, have an extremely strong male aspect in their invocation. The strange squiggles are sigils or signatures.
This amulet is not meant to be worn. It should be mounted on the wall of a room in which One is most often in, for example, a bedroom or office. The Universal amulet is a permanent protection element for One and for all that is associated with One. It protects One's sleep and thereby promotes the recovery of One's energy potential.
Scope: Meeting the Needs / Energy Charge.
