UR20-4DO-PN-2A:

• Digital output modules are available in the following variations: Four DO, eight DO with two or three wires, and sixteen DO with or without a PLC interface link.
• Their primary purpose is to integrate decentralized actuators.
• All outputs are made in accordance with DIN EN 60947-5-1 and IEC 61131-2 requirements for DC-13 actuators.
• Frequencies can reach as high as 1 kHz, like digital input modules.
• The highest level of system safety is ensured by output protection.
• This involves an automatic restart after a short-circuit.
• LEDs indicate both module and channel condition.
• The collection of digital output modules includes specific versions, including the 4RO-SSR module for rapidly switching applications, in addition to the normal uses.
• With solid state technology, each output can receive 0.5 A.
• In addition, there is the 4RO-CO relay module for power-intensive applications.
• It has four CO contacts, is optimized for a switching voltage of 255 V UC, and is meant to switch at 5 A.
• The module electronics power the associated actuators via the output current channel (UOUT).
