Eltek - Model 1010/1010X, 1020/1020X & 651 -Squirrel Dataloggers for Energy Management

Squirrel 1010/1010X and 1020/1020X energy series dataloggers and accessories enable quick, easy metering, monitoring and logging of load usage patterns enabling optimisation of power distribution, ultimately leading to improved reliability of power availability and power distribution plant costs.

The Squirrel 651 datalogger is specially designed for use with the Northern Design NDRail350 (1 x 3 phase load) or NDRail310 (3 x single phase load) energy meters.

Options - Factory installed Text message on alarm

Optional Text message on alarm using and /or remote access, using external GSM modem.

Options - Field installed Memory expansion

The memory can be expanded to 2M readings (about 2,080,000).

Don`t forget that a lot of memory takes time to download and that it is possible to reduce the amount of memory used for a logging run. Eltek loggers download at 38400 baud, and in practice this is about 500 readings per second.

• Logging Modes: Interval / average / event / externally triggered
• Log/Scan Interval: 5 seconds to 24 hours
• Data memory: Internal memory: 250,000 readings Option: 2 million readings Memory modes; stop when full or overwrite current run
• Display: 2 line, 32-character, for readings status monitoring and configuration
• Communications: RS232 half duplex - 2400 to 38.4K Baud Modem compatible protocol
• Darca Plus Software: Configuration, graphing and analysis
• Power supply: Internal: 6 x AA Alkaline batteries External: 9 to 14vDC (1.4watts) Mains adapter: Type MP12U
• Operating Environment: Temperature range:-30 to 65°C Humidity: 95% non condensing. For harsh environments an optional IP65 enclosure is available (type WB6).
• 1010/1010X and 1020/1020X Only:
• Analog Inputs: Accuracy: ±(0.1% of reading, +0.2% of range span)
• Digital Inputs: 0/5V or volt free contacts 8 inputs per logger channel
• Pulse counters: Each counter up to 2Khz signal or 100Hz volt free contact. A total of 650K counts software selectable
