Monitoring Relays
3RS10, 3RS11 Temperature Monitoring Relays
Relays, analog adjustable
■ Overview
The 3RS10/3RS11 analog temperature monitoring relays can be
used for measuring temperatures in solid, liquid and gas media.
The temperature is sensed by the sensors in the medium,
■ Technical specifications
evaluated by the device and monitored for overshoot or
undershoot. When the threshold values are reached, the output
relay switches on or off depending on the setting.
