CONTROL ACCESSORY TYPE: RZ
- Connection to Rekumat burners (RB) or Rekumat radiant tube burners (RS)
- Screw type or mounting rail fastening
- Overtemperature input
- Power dosing input
- Adjustable burner on time
- Function display by LEDs
The Control Accessory is used in connection with a Rekumat burner (RB) or Rekumat radiant tube burner (RS) to calculate the switch on time of the built-in twoposition controller in the controlled member.
The ON time of the burner corresponds to the process conditions.
The control accessory is equippedped with a microprocessor that calculates the power requirements.
Different function versions are available.
RZ-RS (Rekumat radiant tube burner)
Construction:
Plastic housing with open terminals, alternatively with screw fastening (DIN 46121) or snap fastening(mounting railDIN46277)
Dimensions:
150 x 70 x 112 mm (wxhxd)Installation position:
anyAuxiliary voltage:
115 / 230 Vac ± 10 % / 50 – 60 HzPower consumption:
approx. 8 VAInput:
Controllercontact(workingcontact):The contact must be potential-free and is loaded with approx. 20 mA
Analog input: Thermoelement NiCr-Ni with automatic reference point compensation
Output:
