1.2 Brief description
The TMI8 control unit serves for controlling up to 8 electrically operated
clamping devices via a field bus interface. The device can be selective-
ly controlled via DeviceNet, Profibus-DP, PROFINET IO or Ethernet-IP.
Next to the initiators for notifying the end positions Close or Open, up to
8 binary inputs can also be connected. The device can be configured
and the current operating states can be represented using a hand-held
terminal. The operating and error states can be displayed on the device
using the two-digit display.
Connections:
1 input / 1 output

3. Description of the safety function
The functional safety is guaranteed by the safe switching
off of the load voltage on the XS3 by the voltage supply
modules TVM8-Safety 230V or TVM8 Safety 400V.
The safety function in the TMI8 includes only the safe separation of the
load voltage from the other supply voltages. To guarantee the function-
al safety, the TMI8 must always be operated with a TVM8 Safety 230V
or TVM8 Safety 400V.
