It handles both 24 V AC and DC input signals, with a logic \"1\" threshold above 12 V and \"0\" below 5 V. The relay outputs switch up to 5 A resistive or 3 A inductive loads, and can handle lamp loads up to 1000 W. That 3 A inductive rating is what you'll use for small contactors or solenoid valves — the 5 A resistive covers heaters or indicator banks. Rated IP20, so it lives inside an enclosure. Ambient range is 0 to 55 °C; if you have a firmware version ES03 or higher, the cold end drops to -20 °C. ## Signal and timing Input switching times: 1.5 ms on the rising edge, 15 ms on the falling edge. That's fast enough for most discrete sensing — limit switches, pushbuttons, proximity sensors. The relay outputs mechanically switch at up to 10 Hz, so don't plan on PWM or fast counting through these; use a transistor output module for that.","metaTitle":"Siemens LOGO! 6ED1055-1HB00-0BA2 4DI/4DO relay, 5 A resistiv","metaDescription":"Siemens LOGO! 6ED1055-1HB00-0BA2 with 4 digital inputs and 4 relay outputs, max 5 A resistive load, 55 °C ambient, current production, sourced to order.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Digital Input Modules"],"specifications":{"Max.":"55 °C","Min.":"0 °C; ES03 and higher: -20 °C","Depth":"58 mm","Width":"35.5 mm","title":"6ED1055-1HB00-0BA2","Height":"90 mm","24 V AC":"Yes","24 V DC":"Yes","CE mark":"Yes","Mounting":"on 35 mm DIN rail, 2 spacing units wide","FM approval":"Yes","UL approval":"Yes","description":"LOGO!
