BENTLY 1900/65A-01-01-03-00-01 General Purpose Equipment Monitor

Overview

The 1900/65A accepts inputs from up to four channels of vibration sensors (accelerometers or velocity transducers) and two channels of temperature sensors (RTDs or thermocouples). It processes these signals and provides local display via LEDs, as well as relay outputs for alarm and trip functions. The specific configuration 01-01-03-00-01 indicates a particular set of input options and relay logic, making it suitable for a wide range of industrial applications.

Key Features

• Multi‑Parameter Monitoring: Simultaneous vibration (RMS or peak) and temperature measurement.

• Flexible Inputs: Compatible with standard IEPE accelerometers, velocity sensors, and 2/3/4‑wire RTDs or thermocouples.

• Programmable Alarms: Each channel has two independent alarm setpoints with adjustable hysteresis and time delays.

• Integral Relays: Four form‑C relay outputs (rated 5A @ 250 VAC) for direct control of warning lights, horns, or shutdown systems.

• 4‑20 mA Retransmission: Buffered analog outputs for each channel to interface with PLCs or DCS.

• Local Indication: Front‑panel LEDs indicate channel status, alarm conditions, and power on.

• Easy Configuration: DIP switches and rotary switches allow on‑site setup without software.

Technical Specifications

• Power Supply: 24 VDC (isolated) or 85‑264 VAC (depending on ordering option).

• Vibration Input: 0‑10 V peak, frequency range 2 Hz to 10 kHz.

• Temperature Input: RTD (Pt100) or thermocouple (J, K, T) with internal cold‑junction compensation.

• Accuracy: ±1% of full scale for vibration, ±1°C for temperature.

• Operating Temperature: -20°C to +65°C.

• Enclosure: Panel‑mount or DIN‑rail mount (optional).

Applications

The 1900/65A is ideal for critical but non‑primary machinery where continuous monitoring is not yet installed. Common applications include cooling tower fans, centrifugal pumps, reciprocating compressors, and HVAC systems. It can be used as a standalone monitor or integrated into a larger plant monitoring strategy via its analog outputs.

Installation and Configuration

The monitor is housed in a rugged metal enclosure suitable for industrial environments. Configuration is performed via internal DIP switches and potentiometers, eliminating the need for a computer. The 01-01-03-00-01 variant includes specific factory‑set options (e.g., vibration full‑scale range, temperature type) that can be customized on request. All field wiring connects to removable terminal blocks for easy maintenance.

In summary, the BENTLY 1900/65A-01-01-03-00-01 general purpose equipment monitor delivers reliable, cost‑effective protection for a wide variety of rotating machinery, helping to ensure operational continuity and safety.
