- Influences and sensitivity to the radiation pulses in the visible wavelength range
- 6 output relays (2xHigh-speed solid state relays, 3xSignalization relays, IRF)
- Up to 2 binary inputs (OCP start signal monitoring from an external relay)
- 7xLEDs, «Reset» button on the front panel
- CBFP
- Configurable software logic
- Communication port 1xRS-485 (Modbus RTU)
- Time synchronization
