Siemens 3RK1100-1CQ20-0AA3 AS-i K45 4DO Module

Product Description

The Siemens 3RK1100-1CQ20-0AA3 is an AS-Interface K45 compact digital output module designed for IP67-rated field applications . This robust module features 4 digital outputs, each rated at 1 A with a total output current of 3 A at 24 V DC, making it suitable for controlling actuators directly in harsh industrial environments . Connection is facilitated through 4 M12 sockets, and the module supports addressing via a front-facing socket . Please note that the mounting plate (3RK1901-2EA00 or 3RK1901-2DA00) and an external AUX POWER supply (20–30 V DC) for output circuits must be ordered separately .
