Each output has a non-accessible 5 A fuse and an adjustable current limit set via potentiometer. Overcurrent conditions trigger a fast switch-off (1.5x set value, typ. 100 ms) or a delayed switch-off (between 1.0 and 1.5x set value, approx. 5 s), giving you selectivity between short-circuit and moderate overload. Outputs are not parallelable. On power-up, the module delays output connection for 25 ms, 100 ms, or a load-optimised sequence selected via DIP switch—useful when charging downstream capacitive loads. Three-color LEDs per output indicate normal pass-through (green), manual off (yellow), or overcurrent trip (red). An optional non-isolated 24 V remote reset input (sensing >15 V as high) can clear a fault per output. The unit is rated for 97 % efficiency at nominal load. Mounts on DIN rail EN 60715 35×7.5/15. Screw terminals on input accept 0.5...16 mm²; output and signal terminals accept 0.5...4 mm². Enclosure dimensions 72 mm wide, 80 mm high, 72 mm deep; requires 180 mm of vertical clearance for terminal access. Protection class IP20, safety according to EN 60950-1 and EN 50178, emissions per EN 55022 Class B, immunity per EN 61000-6-2.","metaTitle":"Siemens 6AG1961-2BA31-7AA0 Power Distribution Module, 4 Outp","metaDescription":"Active four-output 24V DC distribution module with 97% efficiency.
