12.5 ELDIO (Digital I/O Layer)
Transducer Cable for Digital I/O and Pulse Counter
The ELDIO layer uses the Somat SAC-TRAN-MP Transducer Cable
(1-SAC-TRAN-MP-2-2 or 1-SAC-TRAN-MP-10-2) with an M8 connector and a set of
color-coded pigtail wires. The following table lists the pinouts for the SAC-TRAN-MP
cable when used for ELDIO inputs. The I/O pin depends on the bank connector (i.e.,
|1-4|, |5-8| or |9-12|).
NOTE
The quadrature encoder outputs as specified are for default signal polarity which
assigns the positive direction to clockwise rotation. To reverse polarity, interchange
encoder outputs A and B.
12.6 Vehicle Bus Modules (VBM)
The vehicle bus modules use the Somat SAC-TRAN-MP Transducer Cable
(1-SAC-TRAN-MP-2-2 or 1-SAC-TRAN-MP-10-2) with an M8 connector and a set of
color-coded pigtail wires. The following sections list the pinouts for the SAC-TRAN-MP
cable when used with each available VBM interface.
12.6.1 Transducer Cable for VPW Interface
The following table lists the pinouts for the SAC-TRAN-MP cable when used with the
VPW interface.
NOTE
Always provide the +12 volt REF voltage for the VPW module to function.
