The cold-restart floor is -25 °C (condensation and frost permitted, though commissioning under condensing conditions is not allowed), so the PLC can power up after a sub-zero night without a heater tape. It provides 4 digital inputs that accept 115 V AC, 230 V AC, 115 V DC, or 230 V DC — the signal-1 threshold is >79 V for both AC and DC, with a typical input current of 0.37 mA at signal-1. The 4 outputs are relay contacts rated 5 A resistive (3 A inductive), so they switch small motor contactors, solenoid valves, or indicator lamps directly without an interposing relay. ## Mounting and wiring — panel integration checklist The 90 mm height and 58 mm depth fit standard 200 mm deep enclosures. Supply voltage range is 100–253 V DC or 47–63 Hz AC, so it runs on any standard single-phase mains or DC bus in that window. The relay outputs are not short-circuit protected — add an external fuse or circuit breaker per output circuit, sized for the 5 A resistive or 3 A inductive limit.","metaTitle":"Siemens 6AG1055-1FB00-7BA2 LOGO! 8 Expansion Module","metaDescription":"Siemens 6AG1055-1FB00-7BA2 SIPLUS LOGO! 8 expansion module with 4 digital inputs and 4 relay outputs.
