  • Wide choice of sensors and armatures 
  • pH, ORP, conductivity (conductive), conductivity (inductive), dissolved oxygen 
  • Two-wire controller: supply of power and data with FISCO-bus powered 
  • Certified according to ATEX II 2(1)G EEx ia IIC T4, C1D2 or C1D1 and CSA
  • We are registered at the PROFIBUS®-user organisation.

The advantages

The bidirectional communication with PROFIBUS® PA (Process Automation)offers the following advantages. 

  • Intrinsically Safe Controller
  • Simple and cost effective wiring 
  • Number of instruments per segment is related to power consumption (Ex-Zone (EEx ia) max 10) 
  • Flexible Topology: Tree, Star or Line 
  • FISCO model (Fieldbus Intrinsically Safe Concept) 
  • Communication complies with IEC 61158-2 with 31.25 Kbit/s, MBP (Manchaster Coding Bus Powered) 
  • PROFIBUS® PA and FOUNDATION FIELDBUS® utilize the same Physical Layer 
  • Implementation into PLC Systems via segment couplers via PROFIBUS® DP 
  • Block structure, see picture below 
  • Acyclic data for Alarms, remote operation, configuration and diagnosis 
  • Instruments can be hot plugged (connected and disconnected in operation without interference)
