Siemens 3RK2200-0CT30-0AA3

The K20 4I M8 AS-i compact module is designed for field applications, featuring an IP67 protection class that ensures reliability in harsh environments. This module functions as an A/B slave and provides four digital inputs capable of handling 2- or 3-wire sensors with a supply voltage ranging from 16.5 to 30 V DC. The sensor supply is short-circuit and overload resistant, with a maximum output of 200 mA at an ambient temperature of 40 °C, and 150 mA at 55 °C.

With dimensions of 20 mm in width, 108 mm in height, and 45 mm in depth, the module is compact and does not require a mounting plate for installation. It supports standard pin assignment for ease of connection through M8 screw-type terminals. The operational temperature range is between -25 °C and +70 °C, while storage conditions can range from -40 °C to +85 °C. The module's construction allows for shock resistance up to 15g over 11 ms, making it suitable for various industrial environments.
