SMIO modules are used to increase the number of physical interfaces in IEDs from Scanmatic e.g. SM5049 or SM5059. SMIO-modules are available in different variants, with different physical interfaces, and they make it possible to tailor the system to the specific application.
The following modules are available:
- SMIO SM7552:
- 4 x high precision 0 – 20 mA for current measurement.
- 4 x low precision –5 – +30 V for voltage measurement.
- Internal temperature.
- SMIO SM7553:
- 4 x high precision 0 – 2.500 V for voltage measurement.
- 4 x low precision –5 – +30 V for voltage measurement.
- Internal temperature.
- SMIO SM7554:
- 2 x high precision 0 – 20 mA current measurement.
- 2 x high precision half bridge for Aandreaa sensors.
- 2 x low precision –5 – +30 V voltage measurement.
- Internal temperature.
- SMIO SM7555:
- 12 x isolated digital inputs.
- Internal temperature.
- SMIO SM7556:
- 12 x isolated digital outputs.
- Internal temperature.
- SMIO SM7557:
- 1 x analog RTD measurement.
- Internal temperature
SMIO modules are connected to the IED via the SMIO bus (RS485). Addressing and identification of the different modules is automatic. Each module has a unique ID detected by the IED. The ID together with module type information makes it possible for the IED to automatically identify the presence of a module on the bus. The physical connection is via a 5 pins bus connector. The number of bus connectors can be increase on demand.
