Overview
The Turck BL67-B-1M23-19 is a passive base module in the BL67 series featuring one M23 19-pin female connector for reliable field device integration. BL67 base modules are connected to the right of the gateway, using two screws for each module, and a DIN rail is not required, creating a compact and stable unit. Field devices are connected to the base modules which are available with different connection technology (M8, M12, M23 and 7/8″).
