IO-Link Master UR Series
First in industry FPGA-based IO-Link communication processing and unique design enable first in industry functions and performance.
The interface and compact body design give form to the true needs of the field.
The new standard IO-Link Master is now available.
A single unit to connect digital Sink(NPN) and Source(PNP) I/O devices
A single unit to connect digital Sink(NPN) and Source(PNP) I/O devices.
Not only IO-Link devices, but also digital Sink(NPN) / Source(PNP) I/O devices can be connected together in one unit.
16 channels
Connects to more than twice as many I/O devices as standard IO-Link Master.
Save costs and space.
Each channel can be utilized as a digital IO
Realized the minimum cycle time of 0.3 ms
The IO-Link minimum cycle time achieves the industry's fastest* high-speed response of 0.3 ms.
The response time issue of IO-Link communication has been resolved.
Realization of palm size
Approx. 1/2 the size (W110 x D31.4 x H63 mm) of a standard IO-Link Master (8 channels).
In addition, the number of channels is doubled, which contributes to space saving in the equipment.
- In IO-Link Master with display and operation unit.
Surveyed by OPTEX FA in December, 2023.
Palm sized unit with 16 IO Link ports
10 languages supported
Ten languages can be easily selected in the system menu.
The global design allows for safe and reliable use even when equipment is moved overseas.
Automatic IODD download function
Using IO-Link Master and IO-Link devices of OPTEX FA eliminates the need to configure IODD files.
Supports 7 field networks
The multi-protocol design of this unit can be easily switched industrial Ethernet in the system menu.
Backup / restore
When replacing a sensor, if a sensor of the same model is connected to the same terminal position, the settings before the replacement are automatically written.
No sensor reconfiguration is required, which saves downtime.
Users want real ease of use
OPTEX FA's IO-Link Master is equipped with an OLED display and operation keys that allow users to check, set, and change IO-Link device parameters, maintenance information, and errors without using a PC or HMI.
Easy configuration
Accurate data collection
Larger buttons with the tilted top shape help operators easy setting of parameters.
Easy setup
Parameter settings for IO-Link pressure and flow sensors can be set from a host on the network. This reduces the possibility of sensor setting errors or unintentional setting omissions. The parameters once set can be backed up to the UR Series IO-Link master. If the sensor is replaced with one of the same model, the setting information can be restored to avoid accidentally different information than before.
Miswire / Wire Break Detection
Any point that differs from the preconfigured connection information will be detected as a miswire. Even if power to an IO-Link device (sensor) is cut off due to a wire break, the determination signal of the sensor is maintained without interruption, and the wire break can be detected.
Multi-point / Distributed I/O Control
In addition to IO-Link type devices, sink (NPN) and source (PNP) input/output devices can be connected to the IO-Link master, enabling effective use of remaining channels other than IO-Link type devices connection.
Optimal solutions for pressure sensors and flow sensors
What is IO-Link?
IO-Link is a technology that connects sensors and actuators to industrial Ethernet using digital signals.
Various types of data can be exchanged at the sensor level in line with the IIoT.
Easy sensor setup and status monitoring
Various types of data can be exchanged at the sensor level in line with the IIoT.
This means that batch sensor settings and I/O checks can be performed from the controller, and set-up information can be downloaded from IO-Link Master when replacing sensors.
An error display can also be set to indicate if the sensor is disconnected or otherwise malfunctioning.
As a result, equipment start-up / maintenance time can be reduced and sensor-level predictive maintenance can be performed.
System overview
Streamline equipment operation with IO-Link
Contributes to space saving in the control panel
By converting digital, analog devices, and serial device to IO-Link, no communication program is required and input devices can be combined into an IO-Link Master.
Sensors and actuators that do not support IO-Link can also be connected, enabling ON/OFF control.
Standard sensor cables can be used
A standard 3-wire unshielded cable can be used for IO-Link communication, eliminating the need for a dedicated communication cable.
