Failsafe PLCs for Your Application

In addition to controllers, HIMA also provides safety instrumented systems (SIS). These combine safety-related hardware and software to enable failsafe control of your plants. In this way, you can efficiently and cost-effectively implement functional safety for many applications – from emergency shutdown (ESD) to high-integrity pressure protection (HIPPS).
