remote control potentiometersMicronor’s new MR266 Series Remote Control Rheostats and MR267 Series Remote Control Potentiometers are turn-key devices for upgrading manual potentiometer-based process controls to automated PLC control. The products offer a choice of 4-20 mA or 0-10 V input/output interface for compatibility with a broad range of PLC, DCS, A/D, D/A and other control devices. Mounting options include front panel mount (MR267 only) and DIN rail mount. MR266 Series replace low power (< 5 W) potentiometers in range of 100 Ohm to 100 KOhm. MR266 Series replace high power rheostats in range of 2 Ohm to 50 KOhm with four power options (20/60/170/300 W). The MR266/MR267 Series offer additional features. Three user-adjustable trimpots determine the MIN (4 mA/0 V input), MAX (20 mA/10 V input) and speed (10-120 seconds) set points. An override mode option allows the system engineer to define how the unit shall respond when a user tries to manually override the unit via the front panel knob. Setting the OVERRIDE DIP switch to ON disables analog input control until a Reset is performed.
