Banner Engineering AT-FM-2A-24VDC Safety Relay

Banner Engineering AT-FM-2A is a 24 V AC/DC Duo-Touch two-hand safety relay module that interfaces two actuating devices—one PNP input and one NPN or relay output—to drive two independent safety relay contacts in a guarded-path circuit. Operating from 24 V ac/dc ±15% at up to 250 mA, it provides two normally open safety outputs (K1 and K2) rated to 4 A, plus an auxiliary normally closed output (K3) rated up to 0.5 A; the safety contacts are arranged as two redundant, forced-guided contacts with an auxiliary monitor output, matching typical two-hand control safety architectures. The unit uses a fixed 45 mm width terminal block, includes self-checking circuitry, and carries an IP20 enclosure rating, making it suitable for compact safety relay installations in machinery where a fail-safe two-hand control sequence is required. Note that Banner lists AT-FM-2A as part of the DUO-TOUCH family and indicates this model is obsolete, with corresponding documentation and replacement recommendations available from Banner.
