Setis is available in two hardware versions:
• Setis CPU, which houses the system's intelligence and handles some of the data acquisition/action.
• Setis EXP, which expands the system's capabilities, allowing up to seven Setis EXP modules to be linked on a single module.
Main I/O features:
Digital inputs (SIGNALS)
- Signals: single, double, digital measurements (BCD, Gray or binary), etc.
- Various pickup voltages
- Inputs optically isolated from other signals and control electronics
- Grouping of inputs with a common terminal
Analog Inputs (MEASUREMENTS)
-Each group of 2 measurements has a common terminal
-Measurement groups isolated from each other and from the internal electronics
-Inputs protected against transient overvoltages
-Converter with bipolar input and 14-bit resolution + 1 sign bit + overflow indication
-Minimum sampling period of 600 ms
Digital Outputs (COMMANDS)
- Each double command constitutes two mutually exclusive relay outputs -
"Select before operate" command execution -
Only one command is executed at a time. Except in R8 modules, where 8 simultaneous commands are possible -
Normally open, potential-free contact
- Circuitry for inhibiting false operations
-Hermetic relay:
*High dielectric strength coil-contact: 4 kV.
*Max. switching contact voltage: 380 Vac.
*Max. current: 10 A - 250 Vac.
*DC breaking capacity: 300mA – 125Vdc.
-Dielectric strength:
*Between control contacts: 1000 Vac (1 minute)
*Between outputs and ground: 2000 Vac (1 minute)
*Between outputs and power supply: 2000 Vac (1 minute)
*Between outputs: 2000 Vac (1 minute)
Analog outputs (SETPOINTS)
- 4-20 mA current outputs
- 12-bit resolution converter
International Standards
It is worth noting that SEMI's Telecontrol products comply with the main international standards. They incorporate numerous communication protocols, including the new IEC-61850, thus providing their solutions with a high degree of integration with other equipment on the market. They also offer value-added features that give the systems greater intelligence and autonomy, such as the ability to automate control and management processes directly from the RTUs.
