Accuracy: ±1% of full scale Output

Relay: 2×DPDT (Alarm / Danger), 5A @ 250VAC/30VDC

Buffer output: BNC (original probe signal)

4-20mA analog output (1900/15 not included, core difference)

Power supply and environment

Power supply: 24VDC (18–30VDC) or 115/230VAC (50/60Hz)

Power consumption: Approximately 10W

Operating temperature: -40°C ~ +70°C

Humidity: 5%–95% RH (no condensation)

Status LED: OK, Alert, Danger, Fault Communication

Built-in TIM interface: Compatible with Trendmaster®2000 system

No Modbus/Ethernet (local monitoring type)

✅ Core functions

Single-channel displacement monitoring: Combined with 3300XL probe, measures shaft vibration / axial displacement

Dual threshold alarm: Independent warning (Alert), danger (Danger), with delay ranging from 0.1 to 30 seconds

Local display and diagnosis: LCD real-time value + LED status; probe disconnection / short circuit / over-range detection

Independent / dual-purpose for local or Trendmaster®2000 connection: Local protection or connection to Trendmaster®2000

Key upgrades: Comes with 4-20mA output, can be directly connected to DCS/PLC, no additional modules required

✅ Application scenarios

General industry: pumps, fans, small motors (shaft displacement monitoring)

Oil and gas: auxiliary equipment, non-critical compressors

Power: cooling tower pumps, boiler fans, small steam turbines

Renovation projects: Replace old single-channel monitors, prioritize 1900/17 when 4-20mA signal is required
