Catalog Numbers and Ratings

To properly configure a complete sensor application, you must specify the catalog numbers for a sensor unit, an output unit, an enclosure and power source and a communication cable. Consult the factory for guidance if assistance is needed to correctly specify the system components.

Output Unit


Voltage Output (VAC)

Catalog Number


O1 O2 O3
0-67/0-115 VO-115 -XX -XX -XX
0-10 VO-010 -XX -XX -XX
Note: To complete the Output Unit catalog number, add the required VA value to each of the three output signal fields of the base catalog number.  If no output signal is required for the second or third fields use "00" for null value.  Valid VA values are "01" (1.44), "15" and "25"

The Output Unit can be provided in several different configurations based on the requirements of customer's specific application:

Voltage Output Signal Formats - Output signals are available with standard formats of 0-115 or 0-67 VAC and an optional 0-10 VAC.  Standard VA is 1.44 but optional 15 and 25 VA are available for the 0-115 and 0-67 outputs.  The 1.44 and 15 VA can be provided on all three outputs while the 25 VA can be provided for up to two outputs only.  Other formats may be supported.  Please contact the factory if your device requirements are other than the output formats offered here.

Inputs/Outputs - The Output Unit accepts up to three voltage inputs and provides up to three analog voltage outputs.  This allows a single Output Unit to support up to three Sensor Units of the same or different ratings.  Alternately, the input signal from a single Sensor Unit can be used to provide up to three voltage output signals for three separate load devices (meters, relays, rtu's, etc.)

Power Source - The Output Unit will operate with customer supplied 24, 48 and 125 VDC or 120 VAC.  An optional SEECO supplied 24 VDC power source complete with batteries, battery charger, and battery testing mechanism can be provided, which requires customer supplied 120 VAC.  A solar power source can also be supplied for geographically remote applications.

Enclosure - The Output Unit can be provided complete with an enclosure.  The standard enclosure is provided for most typical applications and is sized to accommodate the output device, terminal blocks for output signal wiring connections, up to three circular, MS connectors and power source inputs.  A larger enclosure is available and is sized to accommodate the above material plus the optional SEECO supplied 24 VDC or solar power source, or other customer supplied equipment (SEL relays, rtu's, etc.)

Communication Cable  
Catalog Number
Base Length
Note: To complete the Communication Cable catalog number, add the required cable length to the base catalog number.  Add leading zeroes where necessary to create a four digit length value, i.e. a 170 foot linear length would be specified as "CAB-0170".

Communication from the Sensor Unit to the Output Unit is digital not analog, providing a maximum cable length of up to 4,000 feet.  The cable length can be specified in 10 foot increments.  One cable is required per Sensor.

The cable has a UV protected black PVC jacket, which is sunlight resistant, impervious to moisture and vapor penetration and is suitable for installation in both wet and dry locations.  Each end of the cable is pre-terminated with a circular MS connector for quick and easy connection to both the Sensor and Output Unit devices.  Cable is suitable for direct burial.
