The ESA system consists of a cRIO (Compact Reconfigurable I/O) controller housed in a NEMA 4X-rated enclosure, equipped with the following I/O modules:
-
Controller — one of the following, depending on the number of motors being monitored:
-
cRIO-9055 (4-slot controller)
-
cRIO-9058 (8-slot controller)
-
-
NI-9242 or NI-9244 voltage bus input card (for potential transformer measurements)
-
NI-9239 voltage input module (for voltage-output current sensors)
-
Current sensors (clamp-on type, supplied by Cutsforth)
NOTE:
The specific enclosure and controller configuration are determined by the number of motors to be monitored and the site voltage class. Refer to the Installation Planning Guide (EZDP-2148) for full equipment lists and enclosure sizing.
Two standard enclosure sizes are available. The specific enclosure is selected based on the space requirements of the configured product:

NOTE:
Enclosures are rated NEMA 4X, UL Listed Type 1, 2, 4, 4X, 12, 13, and IP65/IP66. Conduit holes are not pre-drilled; conduit sizing and placement are customizable per installation. Adequate sealing hardware should be used to maintain the enclosure ratings.
InsightCM™ is Cutsforth's application software for continuous condition monitoring. It runs on a customer-supplied server (see Section 5 for server requirements) and provides:
-
An asset tree for organizing monitored motors and voltage buses
-
Real-time and historical data viewing in multiple specialized viewers
-
Automated fault feature extraction and trending
-
Configurable alarming with optional email notification
-
Integration with plant historians via standard protocols
-
Data export for external analysis
