The REM-1F Digital Display Controller serves as either a pump remote control station or a proportional pump controller (4-20 mA input) or both. The REM- 1F controller can be used to vary the output of any solenoid metering pump with external stroke triggering. This is truly a “plug-n-play” accessory. A simple connection of 4 conductor cable from the REM-1F controller to the external input jack of an LMI® pump is all that is required for start-up. Similar connections can be made to other solenoid pumps. Power is supplied by a 15 VDC source from the LMI® pump through the 4-conductor cable. For other pump brands, an external 9-15 VDC power supply is needed.

The Controller output, in the form of a solid-state contact closure, triggers the electronic metering pump. The output is adjustable to 0-360 strokes- per-minute (spm) or 0-360 strokes-per-hour (sph). In internal mode, a touch of the pressure-sensitive arrow keys varies the output, which is displayed on large, easy to read LCD digits. Pumping rate can be displayed in Strokes, Liters or Gallons, per minute 
or per hour. In the external mode, output is from
0-360 spm or 0-360 sph directly proportional to the 4-20 mA analog input signal. Three meters (10 feet) of 3 conductor cable and connectors are supplied as standard for the 4-20 mA applications. Zero and
span limits and calibrations may be made through the keys of the controller. All configurations changes and calibrations are saved in non-volatile memory.

In the “OFF” position, the 9-15 VDC power source will be present, but the controller output feed rate will be zero. The display will then read OFF The rugged, polycarbonate NEMA® 12 (IP-52) enclosure is easily wall-mounted near the associated pump, or can be remotely located, using standard cable / connectors sets available from UGSI Chemical Feed, Inc.
