Product Description:

The IE2321 extension unit controls input and output operations by using space-saving design in small size. It also has a control voltage with a maximum output of up to 0.5 A protected against short circuit. The load voltage is 24 volts and can operate within voltage swings of -15% to +20%. It allows it to operate well in places where voltage is not stable. It also supplies a maximum output current of 2 A to stabilize the connected equipment.

The unit offers stable and safe operation in systems where extension modules are few. It is suitable to use in systems with narrowly confined space and power consumption. The unit meets protection standards for the industrial short-circuit, ensuring minimum risk of damage under faulty conditions. Its ruggedness against small voltage changes makes it highly suitable for field mounting. It provides optimal signal transmission and current treatment in small spaces for more compact cabinet design. Its electrical ruggedness provides longer term operating reliability in the field. Its solid-state construction is built to be reliable and accurate in control systems. The IE2321 is built for expanding modular systems with less complex flexible infrastructure design. Engineers may utilize it where power density and integrity of control are critical. Sustained current supply protects loads, especially during automated applications.

There are no moving parts, and maintenance is reduced while ensuring uptime is guaranteed. It can also be utilized in rough operating conditions with guaranteed performance in a wide range of industries. It remains stable even under negative conditions with instability of voltage. Its built-in protection function enhances its application to safety-related applications. Its ability to supply power safely and voltage fluctuation control make it a safe unit for extending digital systems.
