MSA 9010/9020 Controller

MSA 9010/9020 SIL Controller


The 9010/9020 SIL controller has an advanced design and innovative features. It can monitor up to 20 channels and is now suitable for SIL 2.



The 9010 controller operates with one independent sensor, while the 9020 operates with two independent sensors per controller module. Each module has an independent power supply for increased system reliability. Both units have full internal diagnostics, reducing false alarms and unexpected failures. The controller switches on the external gas detectors, while the large four-digit LCD display and LED provide essential information such as gas concentration and alarm status.
