  • Page 4: Instrument Description

    Type OM 402PID is a multifunction instrument with the option of confi guration for 8 various input options, easily confi gurable in the instrument menu. In its basic confi guration the OM 402PID has two regulatory relays and two relay alarm outputs. Desired value can either be constant, or defi ned by one of 14 programmes.
  • Page 5 The operation program is freely accessible (www.orbit.merret.eu) and the only requirement is the purchase of OML cable to connect the instrument to PC. It is manufactured in version RS 232 and USB and is compatible with all ORBIT MERRET instru- ments. Another option for connection is with the aid of data output RS 232 or RS 485 (without the need of the OML cable).
