R38s Series are super-simplified to program and use. This system is made with a e-fied sensor that guarantees complete protection from dust and liquids. Each unit has start-up delay which avoids the overcurrent device from being activated. The R38S also features a sensitive touch keyboard.
The soft start function makes it possible to eliminate thermal shock and mechanical stress (due to dilation) that a system undergoes during start up. The On/Off SP1 drives out - SP2 drives out 2 feature helps to keep the set points (the working points) of the devices you are actuating, separate for better control of the system. And the Keyboard Lock feature keeps the controller from being tampered by an unauthorized person.
