USB intrinsic safety barrier for stand-alone keyboard applications, For installation in Zone 2 environments, supplies keyboards in Zone 1/21, 2 USB channels, Data rates up to 480 Mbit/s, Max. cable length 10 m (5 m before device, 5 m after device), Powered via USB, no separate power connection requiredpa

Div. 2 / Zone 2 Ex-rated barrier for use with Class I and II, Div. 2 and Zone 2 keyboardpa

Function: EXTA4-*-K8*

EXTA4-* is an intrinsically safe keyboard with touchpad (EXTA4-*-K4*), joystick (EXTA4-*-K6*) or optical trackball (EXTA4-*-K8*). The interfaces of mouse and keyboard are separated IS-Circuits. Both circuits are lead trough in one connecting cable (connecting cable is included in delivery). The keyboards are designed for panel mounting or for installation in a housing.

The EXTA4-* is designed as accessory for the Pepperl+Fuchs Workstations VisuNet GXP and VisuNet FLX but can be used as stand-alone keyboard in combination with the available barriers as well.
