Eight digital inputs in an IP67 slice
The 3RK5010-0CA00-0AA0 is an IO-Link module K20 that provides 8 digital inputs, each configurable with adjustable input delay times of 1 ms, 3 ms, 15 ms, or 20 ms per module. Rated for a maximum of 400 mA, it operates on a 24 V DC supply (18 V minimum, 30 V maximum) and carries IP67 protection, meaning it withstands washdown environments without an additional enclosure. Mounting is via frontal or lateral wall mounting — the 20 mm width and 45 mm depth fit into tight panel layouts or machine-mount applications.
Pinout and sensor supply per socket
Each of the eight M12 sockets provides sensor supply + on PIN 1, sensor supply - on PIN 3, and the digital input signal on PIN 4 — a standard three-wire sensor interface.
