BK Mikro BKM91,6304247 BKM9I

BK Mikro BKM9 I/O is an expansion module designed to pair with BK Mikro9 control units (the BKM91 family) to extend input/output capability in automated systems; its part number is 6304247. The module provides 10 inputs and 2 powered outputs via plug‑in screw terminals for straightforward wiring of sensors and actuators, and it includes an 8‑pin M12 round connector for touch‑probe interfaces along with a Mini‑USB port for configuration. This expansion is intended to operate with BK Mikro9 control units and is compatible with the BK Mikro9 system’s DIN‑rail mounting scheme (35 mm profile) and ambient operating range of 0°C to 50°C, meeting EN 50178 Class 3K3 requirements. In practice, it enables compact, reliable integration of additional discrete sensors (such as limit switches and proximity sensors) and simple actuator control into tooling, machining, and automation cells, without enlarging the central controller.
