The 6ES7141-5BF00-0BA0 is an ET 200eco distributed I/O block providing 8 digital inputs and 8 digital outputs, each 24 V DC, via M8 shielded connectors (4-pin). Operating ambient spans -30 to 55 °C, with IP65/67 protection for direct machine mounting without an enclosure. Dimensions are 159×30×40 mm (H×W×D). Input signal thresholds: +11 to +30 V for logic 1, -30 to +5 V for logic 0. Outputs switch within 1.2 to 4.8 ms. Functional safety is documented with SIL 2 and Category 3. Isolation between bus circuits is type-tested at 707 V DC, and diagnostic alarms are parameterizable with I&M data sets 0 to 3 for asset tracking.
M8 connectors are shielded; maximum unshielded cable length is 30 m. Electronic short-circuit protection per module guards the sensor supply and output encoder supply (total 0.7 A, max. 4 A from load voltage 2L+). Reverse polarity protection prevents destruction of the encoder power supply outputs. Power consumption is 1.9 W typical, drawn from the 24 V DC network.
