RMC100 SO
SSI Input/Output (SO) Module
The SSI Input/Output (SO) module for the RMC150 allows for synchronizing multiple RMCs to a single SSI position transducer.
The SO module contains two ±10V drive outputs, one SSI input, and one SSI output. The drive outputs and the SSI input can be used for machine control. The SSI output retransmits the position data received from the SSI input as though it were itself an SSI transducer.
This allows the SSI output on one RMC’s SO module to be fed into an SSI input on another RMC’s SSI or SO module. Both RMCs will see the same SSI position data, although the retransmission incurs one loop time of delay in the position data on the second RMC. Any number of RMCs can be chained together in this way, with an additional delay introduced for each retransmission.
A typical application is gearing multiple axes to a feed chain.
The SO module is a modified SSI module, and acts like a standard two-axis SSI module (-S), except that the second axis has an SSI output instead of an SSI input. RMCWin and RMCTools will recognize the SO module as an SSI module, but it will function as an SO module.
