The 6ES7145-1FB31-0XB0: The module is housed in an IP66/67 rated enclosure with M12 circular connectors (4/5-pin), making it suitable for direct field mounting in washdown or dusty environments without an additional cabinet.
Each analog output is configurable for two-wire or four-wire voltage connections and includes channel-by-channel short-circuit protection, with maximum short-circuit current limited to 30 mA. The minimum load for voltage outputs is 1 kΩ, and capacitive loads must not exceed 0.1 µF per channel. Diagnostics are parameterizable and report via a group error SF (red) LED and a diagnostic alarm to the controller. The module also supports substitute values on a per-channel basis, though it cannot connect substitute values—each channel can either output the last value or go to a predefined substitute. Cycle time across all channels is a maximum of 1 ms, with crosstalk between outputs rated better than 45 dB. Typical power draw is 1.5 W, and the module draws up to 75 mA from the backplane supply (L+).
