Power supply units with IO-Link for field Installation

| By Mary Page Bailey and Gerald Ondrey

The compact PSU67 power supply units (photo) ensure energy-efficient, decentralized power supply in modular systems at ambient temperatures of –25 to 70°C. The units have protection to IP67 and are suitable for single- and three-phase applications in modular machine building. The PSU67 units can be installed directly at the machine without any protective measures needed. This makes it possible to dispense with switch cabinets or switch boxes completely. The PSU67 power supply units are available with 15, 20 or 25 A as well as with M12, 7/8 in. or HAN-Q4 terminals. The decentralized power supply units supply 24 to 28 V d.c. directly in the field without any loss, and offer high fail safety thanks to its electronic no load, overload and short circuit protection. Its high efficiency of over 95% ensures an optimum energy balance. The output voltage can be configured directly on the device via an LED interface or remotely via IO-Link. — Hans Turck GmbH & Co.
