1. Ziehl Electronic temperature monitor and controller TR 210 T224071 24
Application for regulating and monitoring one or two temperatures at one or two setpoints (switchable between day/night) in heating, solar thermal, and ventilation systems. Optimization and energy savings in ventilation through differential temperature control. Pre-set basic programs. Highly variable programmable.
2. Ziehl Electronic temperature monitor and controller TR 111 V T 224107.CO 24
The temperature monitor and controller TR 111 V is suitable for use as a temperature monitor or as an electronic two-point controller with high repeat accuracy. It features three measurement ranges in one device, adjustable hysteresis and switching delay, as well as the option to choose between standby and operating current versions, making it versatile. The temperature monitor and controller serves as protection against overheating in processes, systems, and machines. It has an LED display for power on and relay switching status.
3. Ziehl PTC thermistor tripping device MSR 220 KA T 222175.CO 200
PTC thermistor tripping device MSR 220 KA is a motor protection device designed to protect electrical equipment with built-in PTC thermistor sensors against excess temperatures. It is suitable for direct monitoring of explosion-proof motors of ignition protection type Ex e and Ex d in gas explosion hazardous areas (zones 1 and 2) and in areas with combustible dust (zones 21 and 22).
Equipment features include:
- Input for 1 to 6 PTC thermistors according to DIN 44081/44082
- Short-circuit monitoring in the sensor circuit
- ATEX approval according to Directive 94/9/EC
- UL recognized component
- Electronic fault memory (can be switched off)
- Output relay with 2 changeover contacts.
Technical data:
- Outputs: 2
- Operating voltage: 200 - 240 V/50 Hz
- Weight: 150 g
- Measuring inputs:
- Product dimension, width: 22.5 mm
- Product dimension, height: 75 mm
- Type (manufacturer type): MSR 220 KA
- Other technical data: Relay voltage: 5 A/250 V/AC.
4. Ziehl Control relay Level relay NS 20
Use with 3 electrodes as a Min/Max control for filling or emptying a container, with 2 electrodes for overflow or dry run protection. The AC measurement path is completely free of direct current. This prevents electrolytic decomposition of the electrodes and the formation of explosive gas. Isolated conductors can be used as electrodes. In conductive containers, the container wall serves as the base electrode.
5. Ziehl Speed and frequency relay FR 1000 U 226133.CO 24
Speed and frequency relay FR 1000 can be used either as a frequency relay for monitoring the mains frequency in power networks or as a speed relay for monitoring rotating parts in machines and systems. The adjustable start-up delay, response delay, and hysteresis allow for optimum adaptation to the monitoring task.
Features include:
- Voltage input: 80 - 440 V/AC for monitoring frequencies in the range of 10 - 500 Hz
- Input for proximity switches: 2- or 3-wire, NPN or PNP for monitoring speeds in the range of 5 - 99,999 pulses/min
- Scalable 5-digit digital display
- 2 output relays, each with minimum and maximum or window monitoring relay functions, variable programmable.
Technical data:
- Outputs: 2 relays
- Operating voltage: 24 - 240 V DC/AC
- Installation depth: 55 mm
- Weight: 200 g
- Product dimensions: width 70 mm, height 90 mm
- Type (manufacturer type): FR 1000
- Relay voltage: 3 A/250 V/AC.
6. Ziehl Universal voltage monitoring relay SW32V S222279 24
Description Universal Voltage Monitoring Relay SW32V Effective value measurement Monitoring of phase sequence and asymmetry switchable. The SW32V voltage relay is a high-quality voltage monitor with a wide measurement range for monitoring DC, AC, and three-phase voltage networks for over- and/or undervoltage with or without a neutral conductor. In three-phase networks, phase asymmetry and phase sequence can also be monitored. The limit values are set in volts, allowing the device to be used with various nominal voltages. The digital display is used for displaying measurement values and for the precise setting of limit values, switching times, and functions. Areas of application: As a voltage monitor in energy generation and distribution systems, especially in self-generation systems, such as PV systems or combined heat and power plants. Voltage monitoring in machines and systems to prevent errors, damage, or failures in sensitive facilities or devices. Features: Effective value measurement monitoring.
7. Ziehl Voltage and frequency relay UFR1001E
Monitoring of frequency and voltage, monitoring of vector transitions. Individual fault safety with monitoring of the connected coupling switches. Alarm counter and recording of total alarm time. For use in medium voltage systems with 8 programmable limit values.
8. Ziehl Direction of rotation relay DRR10 no extra power supply required Measuring inputs 3 AC 400 V
With the direction relay DRR10, the phase sequence is always correct, meaning that the motors always start in the right direction, even if the power supply or connection cable is incorrectly connected. It is particularly suitable for mobile systems (pumps, mixers, compressors) that operate on varying networks. The device features a thermistor over-temperature protection. For continuous currents higher than 3 x 12 A, two contactors (please order separately) can be connected in between.
