Akytec MK210-302 Short Manual

Digital I/O module
Short guide
1. Overview
MK210-302/312 is an extension module with 12 inputs and 4 digital
outputs (relays).
The module has two Ethernet ports for connection within the daisy chain
scheme. If the module fails or the power is turned off, the data
transmission will be fed directly from port 1 to port 2 without
disconnecting.
The full User Guide is available on the device page at www.akytec.de .

4. Installation and connection
Before installation make sure there is enough free space for connecting
Yes
the module and placing the wires. The module is mounted on a DIN rail
II
or on a vertical surface using screws.
Installation of external connections is carried out by a wire with a cross
section of not more than 0.75 mm
For stranded wires, use end sleeves.
After installation, put the wires into the cable channel of the module
housing and close the cover.
If necessary, in order to remove the terminal blocks of the module, loosen
12
the two screws at the corners of the terminal blocks.
CAUTION
Connection and maintenance is performed only when the
module power and the power to all devices connected to it is
turned off.
