SEP

sep

The SEP technological and measuring unit is a device designed for monitoring and setting digital and analog inputs and outputs. 32-bit impulse counters are also available. SEP was developed as an accessory to the MORSE communication for points in technological networks where local autonomous control is not necessary.

SEP works as a slave which is controlled by MORSE equipment (radio modem, GPRS modem, controller…). Read and set states are transferred to the assigned address via the MORSE network.

Typical areas of use

  • Supplementing control technology connected to the MORSE network
  • Remote “mirroring” of inputs to outputs and vice versa between various points of the network (point-to-point, point-to-multipoint)
  • Remote reading/setting up of digital/analog inputs and outputs using standard visualisation programs via the MODBUS protocol

Benefits

  • Galvanically isolated inputs and outputs
  • Resolution of A/D and D/A conversion 12 bits
  • Voltage and current inputs and outputs
  • Communication using MODBUS protocol
  • LED indication of the status of digital inputs and outputs
  • Separate 32bit impulse counter on each digital input
  • Robust all-metal case
  • Mounted on a DIN rail
