The WD-19506-10 RES 1000 series 1/4 DIN resistivity controllers have an advanced set-up mode to easily customize features. Their 0 to 2000 second selectable time delay and adjustable set point hysteresis bands mean you can tailor control relay action to meet your needs.
Each unit is selectable for isolated 0-20 or 4-20 mA transmitter/recorder output; 110 or 220 VAC; normally open or closed relays; and manual or automatic temperature compensation. The compact 1/4 DIN size fits into standard panel cutouts. The IP54 rated front panel keypad is weather resistant. Includes mounting hardware.
