-13°F to 149°F (-25°C to 65°C)

ELMA offers over-signal protection and programmable signal loss protection. By using an internal dip switch, you can program the ELMA to either freeze at the last setting or drive to zero in the event of a signal loss. This means an added level of protection for your pumps as well as your process.
