Analog Alarms

Fail-safe and non-failsafe alarms are available from DIN-rail mount devices to front-of-panel displays offering up to four contact relays. These alarms feature digital setpoint controls, delay timers, and universal inputs. M-System alarm series are used from simple on/off pump control to back-up alarm systems in the event of a PLC/DCS failure.
