SCM2 – FIELD

Hasler® controller

Contrôleur électronique embarqué pour les doseurs HASLER Group
Logo de la marque Hasler

The SCM2 is used for any type of HASLER® feeders
The SCM2 (Smart Control Module) is a single feeder control module to acquire and process feeder input data, command signals and to pilot the motor drive unit.

Feeder and Control Module - All in one

  • No switch cabinet needed
  • Less cabling on site
  • Direct serial communication with host system through various optional protocols.

Configuration and maintenance software allowing

  • Read & Write of parameters
  • Configure remote Inputs / Outputs
  • Diagnostics (data acquisition, trend graphic recorder, etc.)
  • Remote maintenance

Communication with the Host Sytem

  • Modbus TCP (Ethernet)
  • Modbus RTU (RS422)
  • Allen Bradley Data Highway (RS422)
  • Siemens 3964R (RS422)
  • Profibus DP (RS485)
  • Device-Net
  • Modbus Plus
