The E 32S interface converts the signal generated by the touch probe into a form which can be used by the machine tool CNC.

Located on the front panel of the unit are terminals for the I/O connections and some LED 's to indicate the following:

• Green LED:lit to indicate “power ON ”
  
  
• Green LED:indicates the status of SEL A and SEL B inputs
  lit when the inputs are selected by the CNC
  
  
• Yellow LED:indicates the status of the touch probe:
  lit when the probe stylus is deflected;unlit when the probe is seated.
  

Further to HF probes E32S interface also allows the connection of a second Touch probe with hard-wired connection. In this way it is possible to use only one interface for both part inspection and tool setting applications.

They can be selected manually by dip-switch, or automatically with machine logic input.

In order to meet any application requirement, the following connections are possible:

- One touch probe with H.F. connection and one with hard wired connection.
- Two touch probes with H.F. connection.
- Two touch probes with hard-wired connection.

E32S interface technical features
Power supply	nominal 24 VDC (18-35 V)
Power input	120 mA max.
Output type	Solid State Relay (SSR) 50 V; 40 mA
