Product Description:
The Danfoss 195N1123 Low Voltage Drive focuses on process oriented operations and ensures steady control for continuous industrial automation tasks. The drive's circuitry accommodates a maximum current of 30 milliamps which defines safe operating boundaries and protects both the drive and connected components from potential overload.
The 195N1123 drive can tolerate a slight vibrating force equal to 0.1 gram which suggests it has been assessed under mild mechanical shaking. It is designed to read an incoming control current that begins either at 0 or 4 milliamps and extends up to 20 mA. Its control input lines will endure up to 20 volts of DC and its ceiling ensures that unexpected surges or slightly elevated signals remain safe for the circuit. Its housing follows the NEMA 1 standard which suggests it is mainly for indoor usage as it offers protection from contact and some dust. This drive kVA is 22.2 which is a measure of the total electrical load it can handle and takes into account both active and reactive power. Its base casing provided is a normal protective covering that is sufficient for regular industrial conditions. The module is able to supply mechanical energy equivalent to 20 horsepower which suggests the size of the motor it can drive.
The 195N1123 drive accepts control signals in the range between 0 and 24 volts in DC using an arrangement of a positive logic. It encounters an electrical opposition of about 4000 ohms when a signal enters which defines the amount of current that draws from a connected sensor or control device. It is featured with a single analog channel for current input which allows measurement or control through one process loop at a time.
Frequently Asked Questions about 195N1123:
Q: How does the Danfoss 195N1123 drive handle continuous process operations?
A: It is designed to maintain stable control loops, reducing fluctuations in automated tasks. This ensures consistent output in systems like conveyors or mixers.
Q: What does the 30 mA input current limit imply for installation?
A: It means the control wiring must be paired with compatible sensors or controllers. Exceeding this could risk circuit damage or inaccurate signal reading.
Q: How does vibration resistance affect long-term reliability?
A: With tolerance for minor oscillations, it can withstand routine plant vibrations without loosening connections. This increases operational lifespan in dynamic environments.
Q: Why is having a single analog input significant for process control?
A: It restricts simultaneous measurement to one loop, simplifying system design but limiting multi-signal monitoring. Engineers must integrate external controllers if more channels are needed.
Q: How does the 195N1123 drive’s input scaling of 0/4–20 mA help in practice?
A: It allows flexible interfacing with a variety of sensors. This adaptability supports both legacy 4–20 mA loops and modern 0–20 mA systems.
