Product details

The 6ES7122-1FA00-0AA0: This is a spare part for the SIMATIC SC system — a single digital output module rated for 120/230 V AC, 1 A continuous, with zero-crossing switching to reduce contact stress on AC loads. At 10 mm wide it fits tight DIN-rail slots; it takes one slot out of eight in a SC subrack. The output is isolated from the backplane bus, tested at 2500 V DC. Headroom: continuous current bumps to 1.1 A at 40 °C ambient, and surge is 10 A for 2 half-waves. Switching speeds are modest — 50 Hz resistive, 10 Hz inductive (DC-13 / AC-15), 1 Hz lamp loads. No diagnostics or alarms on this module; status is a green LED per channel.
