01 Product overview
One display.
Your vehicle design.
asis®Tacho combines actual speed, target speed and two configurable indicator symbols in a compact railway display.
During operation, asis®Tacho receives actual and target speed via analogue inputs or vehicle networks, converts the values into a clear analogue pointer and digital speed display, and controls two configurable status or warning symbols. Brightness, scale, pointer, colours and additional content are adapted to the vehicle project. Configuration is performed through USB or the web interface, while the shallow housing and latch mechanism simplify retrofit installation.
02 Core capabilities
Multiple interfaces
Use 0-10 V, 4-20 mA, CANopen, sdxCAN, TCP or TRDP.
Configurable symbols
Two indicator symbols support two colours and replaceable insert strips.
Fast commissioning
Configure through USB, the asis®Tacho Configurator or web interface.
03 Display concept
Project-specific on screen and glass.
Configure the central speed display and select individual symbols without changing the base device.
