The GuardPLC 1200 is a safety-related compact Programmable
Electronic System (PES), which is designed in accordance with IEC
61131. Despite its small size, it complies with the requirements for a
control system with the safety integrity level (SIL 3) according
IEC 61508.

Power Rating
The GuardPLC 1200 is designed for smaller applications that
require functional safety and that can be serviced with a fixed
number of I/O points. The compact size of the GuardPLC 1200
combined with DIN rail mounting allows deployment even under
cramped space conditions.
