TT-S 4- or 6-stage step controller

TT-S4/D or TT-S6/D is a microprocessor-based step controller intended for control of electric heating coils, four or six relays. It can be used with any controller with a 0…10 V DC or 10…2 V DC output signal. The step controller also have an analogue output (0…10 V) for control of an electric heating controller to give proportional heating between steps.

Main features:

• 4- or 6-stage
• control signal 0...10 V or 10...2 V DC
• analogue output
• settable limit for number of steps
• built-in testing function for simple start-up testing
• intended for DIN-rail mounting
