• Velocity Channel: Scale factor range from 5 to 1000 mV/in/s. Full scale range covers 0 to 50 in/s peak.
• Radial Vibration Channel: Scale factor range from 5 to 1000 mV/mil. Full scale range goes up to 160 mil peak-peak.
• Thrust Channel: Scale factor range also from 5 to 1000 mV/mil for axial position monitoring.
• Temperature Range: Operating temperature from -30°C to +65°C (-22°F to +149°F). Storage temperature from -40°C to +85°C (-40°F to +185°F).
• Environmental Tolerance: Handles up to 95% humidity non-condensing. Vibration limitation at 3 g ensures durability.
• Speed/Keyphasor Input: Supports RPM range from 1 to 120,000. Threshold voltage resolution at 0.1 Vdc.
• Proximity Transducer Interface: Supplies -22.8 to –25.2 Vdc. Maximum rated current at 15 mA with short circuit protection.
• Magnetic Pickup Input: Adapts to sensor 284947 output. RPM range from 200 to 120,000 for versatile use.

Outputs and Communication Interfaces

• 4-20mA Outputs (2300/20): Two isolated outputs with internal loop power. Load resistance range from 0 to 600 Ω. Resolution at 0.3662 µA with 1% accuracy.
• Buffered BNC Outputs: Three BNC connectors provide two vibration outputs and one speed output for diagnostic use.
• Relay Outputs: Two dry-contact relays support normally energized or de-energized modes. Maximum switching power at 1500VA AC or 150 Watts DC.
• Ethernet Communication: 10Base-T and 100Base-TX conforming to IEEE802.3. Maximum cable length at 100 meters (328 ft.).
• Contact Inputs: Three contact terminals allow configuration lock, latched alarm reset, and monitor bypass functions.
• LED Indicators: OK, protection fault, user inhibit, bypass, relay status, TX/RX, and channel alarm status LEDs for quick diagnostics.

Frequently Asked Questions (FAQ)

• What is the accuracy of the 4-20mA output?
  The 4-20mA output provides ±1% accuracy over the full operating temperature range. Resolution reaches 0.3662 µA with 100 ms update rate.
• Can I use external powered loops with the 4-20mA outputs?
  No, the two 4-20mA outputs will not work with an externally powered loop. They use internal current loop power supply only.
• How does the monitor handle network disruptions?
  During network loss between the monitor and System 1, the 2300/20-00 stores at least 5 alarm data captures. This requires System 1 Evolution 21.1 or newer and firmware 3.2 or newer.
• What is the battery life for the real time clock?
  When powered, the RTC battery lasts 38 years at 50°C. Without power, it lasts 12 years at the same temperature.
• Does the monitor support Keyphasor transducers?
  Yes, Keyphasor transducers support multiple events per revolution. Event ratios work for speed inputs up to 20 kHz.
• What is the relay contact life specification?
  Relays last 100,000 cycles at 5 amps, 250 Vac. They also last 200,000 cycles at 1 amp, 24 Vdc.
