The 6AG1331-7RD00-2AB0: Four analog inputs accepting 0 to 20 mA or 4 to 20 mA, terminated on a 20-pin front connector. Input resistance sits at 50 Ω per channel, so the loop sees a standard burden. Module carries Ex i intrinsic safety protection—zone-mount with confidence. Reverse polarity protection on the 24 V DC supply. Diagnostics via red SF and per-channel F indicators; group error signal reports on the backplane.
Rated -40 °C minimum to 70 °C maximum operating.
ATEX II 3 G Ex nA [ib Gb] IIC T4 Gc, FM Class I Division 2 Groups A B C D T4, and UL File E239877.
Uo 25.2 V max, Po 431 mW max. PTB test number Ex-96.D.2092X.
