Description
The Siemens SIMATIC S7-1500 F-DQ 8x24VDC/2A PPM provides 8 fail-safe digital outputs for controlling safety-related 24 V DC actuators. The outputs support PPM or PM switching, allowing current-sinking and current-sourcing operation depending on the configured mode, with a maximum output current of 2 A per channel and a maximum total module current of 16 A under the specified horizontal installation and temperature conditions. The module also supports 10 W lamp loads, short-circuit protection, overload protection, and open-circuit detection, making it suitable for reliable switching of safety-related actuators.
The module communicates with fail-safe SIMATIC controllers using PROFIsafe and supports diagnostic functions including wire-break, short-circuit, supply-voltage, overload, and group-error monitoring. It provides channel-status and diagnostic LEDs together with RUN, ERROR, and PWR indications for straightforward system monitoring. The module supports shielded cables up to 1,000 m and unshielded cables up to 500 m, while its safety architecture can achieve PLe and SIL 3 under the specified operating conditions. With its 35 mm housing and 300 g weight, it is designed for S7-1500 and ET 200MP safety-related I/O installations.
