I/O Extension, SK TU4-IOE, ...-M12
The internal I/O units can record sensor and actuator signals. These can be used for a drive function or
forwarded to a host bus system (e.g. Profibus or CANopen). Up to two I/O modules (and combinations: 1 x
SK CU4-IOE and 1 x SK TU4-IOE) can be connected to an inverter (up to hardware version V1.1 R1 and
firmware version V1.0 R1 of the I/O - extension and firmware version V1.1 R2 of the frequency inverter only
the evaluation of one I/O - extension is possible for each frequency
inverter.).
The I/O extension SK TU4-IOE-… requires an SK TI4-TU-BUS
Adapter Unit. Communication with the frequency inverter(s) is via
the system bus. All connections (power supply, system bus,
sensors,...) are made via the terminal block of the BUS Adapter
Unit. The M12-versions of the I/O - extension (SK TU4-IOE-
M12 )
also provide M12 connections for each of the digital inputs and
outputs on the front side.
• 4x digital inputs
• 2x analog inputs
• 2x digital outputs
• 1x analog output
• Status LEDs: BG status, BG fault
• Additional LEDs, M12 version: Dig. In 1 - 4, Dig. Out 1 - 2
• DIP switches for selection
0 - 10V, -10 - 10V, 0 - 20mA, 4 - 20mA
• DIP switches for: addressing, bus termination
Control connections SK TU4-IOE(-…)
The double spring terminal block of the BUS -Adapter Unit is colour coded to indicate the three different
potential levels .
A separate voltage source should be used to supply the DOs. However, it is also possible to implement the
supply of the DOs by bridging the 24V o and GND o with one of the terminals of the system bus level (24V
and GND). However, in this case it should be noted that this produces an increased risk of errors on the bus
cables.
The sensors and actuators are connected to the terminal block. Alternatively, the SK TU4-IOE -M12 module
enables connection of the digital I/Os via the M12 round plug connectors (Socket, 5-pin, A-coded) on the
front of the module.
Double use of the inputs via the terminal block and the M12 round plug should be avoided .
