Characteristics and functionality of SEM SC11 :

12 or 14 binary inputs,

2 transistor DC 24 V binary outputs,

two enhanced relay-semiconductor binary outputs for direct control of switching devices,

one relay-semiconductor binary output with a variable polarity for direct control of the commutating
device drive (control current up to 30),

measurement of the drive control current;

supply voltage measurement,

the RJ45 link for the PAN 1 or PAN 3 operator panel,

the RS-485 link for communication with a telemechanics driver or the SEM SB11 device - the MODBUS-
RTU protocol,

self-monitoring functions (STATUS led)

reprogramming functions (through both transmission ports),

programmable logic, including algorithms for monitoring and control of the commutating device,

test profile for diagnosing the correct operation of the device,

algorithm of return to the secure state after a failed commutating operation;

commutating operation recorder with the registration time of 20s.

remote and local modes of operation.
The following applications are used for configuring and reprogramming the device:

ELF – Parametrisation, logic design, driver status display,

FlashArm – reprogramming the driver,

appSC – specialized application tool adapted to the SEM SC11 to configure basic parameters, change
the profile of logic and view the state of binary inputs and outputs.
