It also offers diagnostic alarms, a wire-break detection function, and status LEDs for RUN, ERROR, RxD, and TxD. ## Backplane power and physical fit The module draws 50 mA from the S7-1500 backplane bus, with a typical power loss of 0.6 W. It mounts directly on the standard S7-1500 mounting rail and occupies one slot. Dimensions are 127 mm deep, 35 mm wide, and 147 mm high — matching the single-wide form factor of the S7-1500 series. Isolation between the backplane bus and the interface is tested at 707 V DC type test, which provides reasonable protection against ground loops and transient pickup common in industrial environments. Operating temperature range is 0 to 60 °C horizontally and 0 to 40 °C vertically, so it can sit in a warm cabinet near drive power stacks without forced cooling concerns.","metaTitle":"Siemens 6ES7541-1AD00-0AB0 CM PtP RS232/422/485, 115.2 kbit/","metaDescription":"Siemens 6ES7541-1AD00-0AB0 CM PtP module for S7-1500.
