Please note, Pace DC Current Sensors have been discontinued.
DC Current Sensors
Connect directly to any XR450 or XR5-SE Data Logger. No external power is required.
- Single 5 Vdc supply, consumes less than 14 ma
- 2 kVRMS Isolation (some models 3 kVRMS)
- Very low internal resistance
- Bi-directional operation
- Rugged epoxy encapsulated housing
- 3 meter (10 FT) cable
DC100A Current Sensor (±100 amps dc)

Limitation:
The XR450 Data Logger and the XR5-SE Data Logger may power up to three (3) DC Current Sensors. Some combinations of sensors may reduce the above count by 1, please contact Pace with your requirements to confirm.
The discontinued XR440 Data Logger may power up to two (2) DC Current Sensors.
Note: If sensors are powered by an external power source, then there is no limitation: up to four (4) may be connected to the XR450 and up to eight (8) may be connected to the XR5-SE.
