Item Description
Renishaw OMI-2C Assembly Heidenhain/Siemens New with 1 Year Warranty
The OMI-2C provides an interface between the machine controller and Renishaw’s range of modulated transmission probes, such as the OMP60. The OMI-2C converts optical signals into electrical signals suitable for use by the machine controller. The OMI-2C converts electrical signals from the controller into modulated optical probe signals . This facility allows the machine controller to be used to optically switch the probe on and off . When in operation, the OMI-2C will report the following probe conditions via a multi-colour LED: Probe status - Error - Low battery
Performance Envelope of OMI-2C & OMP60 Probe
OMI-2C Electrical Outputs and Inputs
OMI-2C Outputs
The OMI-2C has three electrical outputs which are driven relative to the ground connection:
Probe status (pin 4) Error (pin 5)
Low battery (pin 6)
The maximum rated sink or source current per output is 20 mA . If this current is exceeded, the OMI-2C isolates all outputs and the visual diagnostics LED will flash red. When an 8 m Renishaw cable assembly is used and outputs are driven high, they may be up to 2 V below the supply voltage . Alternatively, when the outputs are driven low, they may be up to 2 V above 0 V. When a 15 m Renishaw cable assembly is used and outputs are driven high, they may be up to 2 .5 V below the supply voltage . Alternatively, when the outputs are driven low, they may be up to 2 .5 V above 0 V .
NOTE: Refer to parts list for Renishaw OMI-2C cable assemblies .
The OMI-2C will respond to a received probe trigger signal with a delay of 500 μs ±15 μs . The time delay from the physical probe trigger to any output change will depend on the configuration of the probe .
OMI-2C Input
The OMI-2C has a single electrical input that allows the machine controller to switch the probe on and off . The start input (pin 3) must be connected to the machine’s start and stop M-code. When the input is active (15 V to 30 V, 19 mA@30 V), the probe is switched on.
