Features

Contactor control for door operators up to 3 kW, running on electronic or mechanical limits.

Works with Robodor RARE, KOSTAL and GFA absolute encoders, or with mechanical limit switches.

A cycle counter showing total openings since installation, for maintenance planning.

Support for pneumatic (NC) safety edges and dynamic optical OSE systems, with two NC emergency-stop / safety-chain inputs.

Two programmable relay outputs and a 230 V AC / 2 A brake output.

A stored fault history and code-based diagnostics on a text display, with a selectable menu language.

Optional Integrations

Entry/exit extension for locks or traffic lights/oncoming traffic control can be added.

A four-channel rolling-code remote control can be integrated.

Front/rear radar and photocell sensors can be installed.

An external button system can be added.

A tunnel system connection can be established.
