The IOC 16T Input / Output Card acts as a signal interface for the VM600 series CMC 16 (Condition Monitoring Card). It is installed in the rear of an ABE 04X or ABE 055 (Portable CMS) rack, and connects directly to the rack backplane via two connectors.
Each IOC 16T is associated with a specific CMC 16 and is mounted directly behind it in the rack. The IOC 16T contains a terminal strip to connect the transmission cables coming from transducers and conditioners. However, if these signals are already available via the VM600 backplane ‘Raw Bus’ and ‘Tacho Bus’ lines, then these can be selected directly without any need for additional wiring.
The card protects all inputs against electromagnetic interference (EMI) and signal surges and also meets EMC (electromagnetic compatibility) standards.

Tacho inputs, signals from accelerometers, velocimeters and proximity probes, or any dynamic or quasi-static signals are conditioned by dedicated circuitry which performs tasks such as pulse shaping, level adjustment and AC/DC selection.
Micro-switches (DILs) are provided to facilitate selection of conditioner and access method (i.e. screw terminals or backplane). The IOC 16T also provides isolation from the plant and ensures feedthrough of inputs to the CMC 16.
Two methods of communication are supported; VMEbus connection to a CPU M module in slot 0 of the VM600 rack and subsequent Ethernet link, or direct isolated multi-drop RS-485 serial connection1 via RJ connectors provided on the IOC 16T.
