  • Page 9: Introduction

    940 Professional IC Vario instrument can be expanded with up to 3 942 Extension Module Vario instruments. The 942 Extension Module Vario SeS/PP can be used in IC systems where an additional module for sequential suppression is needed. The 942 Extension Module Vario is operated using MagIC Net software, just like the IC instrument.
