IO-Link Communication module EP-5324

5324
The EP-5324 module is an IO-Link master according to the IO-Link specification V1.1.2. One
IO-Link device can be connected to each connector. The IO-Link devices must conform to
port class A. Port class B is also possible if additionally, potential distribution modules are
used. One digital input can be used additionally with each connector
.
Process data are exchanged with the connected IO-Link device via each IO-Link port.
Additionally, acyclic data can be exchanged over here (diagnostic data, parameter data,
status information data). The parameter data of the connected IO-Link devices can be
stored in the master module, where they are managed by a parameterizing server (data-
storage). Thereby it is very comfortable to change the IO-Link communication module or a
single IO-Link device (from IO-Link specification V1.1 on
).
The four communication channels can be used as digital inputs or outputs together with
standard field devices. A status LED is assigned to each channel. The module electronics
supply the connected sensors with power from the input current path (IIN). The inputs are
protected against voltage surges and overcurrent. Voltages that exceed ±30 V may cause
the destruction of the module.
