ARCUS-EDS 30513261 SK20-TC-VOC-2B

ARCUS-EDS 30513261 Product Description

The Arcus-EDS SK20-TC-VOC-2B KNX sensor is a specialized device for measuring and controlling the temperature and the level of VOC (Volatile Organic Compounds) in indoor air. This sensor is designed to be integrated into home and industrial automation systems, offering a range of climate control capabilities.

Technical characteristics

• Temperature Measurement Range: -20°C to +80°C with a resolution of 0.02°C and an accuracy of ± 0.4°C (between 5°C and 60°C), otherwise ± 0.8°C.
• VOC Measurement Range: 400 to 10,000 ppm (CO2 equivalents).
• Supply Voltage: 21-32 VDC (KNX bus voltage).
• Power Consumption: Approximately 240 mW at 24 VDC.
• Operating and Storage Temperature: -25°C to +80°C.
• Ambient Humidity: 10% - 95% RH (non-condensing).

Control functions

• Temperature and VOC Control: The sensor measures temperature and VOC level and can be configured to control heating and cooling applications.
• Temperature Setpoint: Setpoints for Comfort, Standby, Economy and Protection, selectable through KNX HVAC objects.
• Setpoint change: Modification of setpoints using KNX objects.
• Storage of Minimum and Maximum Temperatures: Storage of minimum and maximum temperatures.
• Heat and Frost Alarm: Alarm functions for extreme temperatures.
• Fan Control: Fan control via external inputs.
• Adjustment of Setpoints and Maximum Temperatures: Adaptation of setpoints and maximum temperatures.
• Controller Output: Controller output 0... 100% or programmable PWM for thermal actuators.
• Valve Flushing Function: Valve Flushing Function.
• Second Auxiliary Controller: Second auxiliary controller as an auxiliary controller.

Logical and Input/Output Functions

• Binary contacts: Two binary contacts.
• Logic Blocks: Four logical blocks for the logical connection between internal and external signals.
• Logical Inputs/Outputs: 10 associated logical inputs/outputs.
• Logical Functions: “AND, OR, NOT, XOR” logical functions for binary signals and “+ - *” functions for 8-bit values.
• Conditional Event Forwarding Function: “=” function for conditional forwarding of events.

Installation and Configuration

The sensor is configured using the ETS software (Version 4 or higher) and the related application program. The sensor is supplied unprogrammed and all functions are programmed and parameterized with ETS.
