Product description
Connectors, buttons and LEDs description
The combined device MECps640 merges the functionalities of two
different system devices. In addition to coupling two TP lines and
providing full TP line coupler functionality the MECps640 powers the
secondary KNX TP Line. Having a very small footprint of only two units, the
efficient device generates a stable KNX system voltage of 30V DC. The
flexible MECps640 can be used as line coupler, area coupler or repeater.
Basic line coupler functionality is coupling a TP main line with a TP subline
providing galvanic isolation in between. Traffic can be filtered according to
the installation place in the bus system hierarchy or according to the built-
in filter tables for group-oriented communication. Long messages with up
to 240 bytes APDU are supported. Configuring from the subline can be
disabled. The subline can be reset via push-button press.
To ease commissioning and troubleshooting, functions like a configurable
Manual Function to temporarily deactivate filtering are available. The
Manual Function can be activated by a single button press on the device
and its switch-off after a pre-set time period is automatic.
MECps640 is suitable for 35 mm DIN rails and installation in distribution
boards. The supply of subline is overload-proof and short circuit
protected. LEDs indicate the device state and the state of the lines.
Configuring can be done with the ETS.
Requirements of Directives EMC, RoHS and LVD are met. Standards for
residential, commercial, and industrial environments are fulfilled. The full
