Features

Six programmable inputs, each assignable to a function such as open, stop, close, fire alarm or airlock.

Three separate safety-sensor inputs, supporting pneumatic (NC) safety edges and dynamic optical OSE systems.

PLC integration over a Modbus RTU / RS-485 interface (115200 bps, 8-N-1).

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

Three programmable relay outputs for door status, warning light, alarm or external lock control.

Separate torque parameters for opening and closing, a stored fault history, and on-screen monitoring of motor speed, current and voltage.

Optional Integrations

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

A metal detector system can be attached.

OSE security system can be added.

Front/rear radar and photocell sensors can be connected.

An external button system can be installed.

A tunnel system connection can be established.
