Siemens ET 200SP Series Safety Module, 24 V

Use this digital iinput module from Siemens for the reading of sensor information in an automated system. It meets the requirements for safety applications and communicates with a fail-safe SIMATIC S7 CPU (central processing unit) by means of PROFIsafe. The module is suitable for both centralised and distributed configuration and includes short-circuit protection for enhanced electrical safety. Its hardware has automatic encoding for increased accuracy and reduced storage-space needs, while its diagnostic function has an alarm to warn you of a malfunction. This module is easily integrated into your automated industrial-control system and designed for long-term reliability.

Compact, modular design to save on space and make it easy to configure with other modules
Bright LED (light-emitting diode) warning lamps for a visual alarm that's easy to see
Extremely low probability of failure even when used in high demand or continuous mode

This device has dimensions of 15 (width) x 73 (height) x 58mm (depth), so it's suited to systems where space is limited.
