funcTiOn ValVE BlOck aiRlinE Ex
Valve block AirLINE Ex Type 8650 has fluidic connections in addition to the electric contacts to the ET
200iSP connection
•
for central compressed air supply (or other neutral gases),
•
for connecting pneumatic actuators, and
•
for consolidated exhaust air disposal.
The valve block is electrically supplied by the ET 200iSP (its PowerSupply module), while actuation occurs
via the interface module of ET 200iSP.
The electronic module of the valve block control the valves of the valve block like digital outputs, and
transmit data (diagnostics, etc.) to the interface module of ET 200iSP. The valves then vent and drain the
connected pneumatic actuators via the work connections.
The connection segments of the valve block (REV.2) can optionally be equipped with a pressure switch or
pressure sensor. This simplifies the automated monitoring of the supply pressure.
An on/off valve can optionally be flanged onto the connection segments of the valve block (REV.2).
This solution provides a very compact means to disrupt the valve block’s central compressed air supply
and to ventilate the valve block, including all connected pneumatic actuators. In this manner the device can
also be used for applications in which security requirements must be ensured. The integratable pressure
sensors/pressure switches can increase the achievable level of security (degree of diagnostics coverage).
