BENTLY 1900/65A 172323-01 General Purpose Equipment Monitor

Overview

Designed to protect non‑critical assets such as cooling tower fans, boiler feed pumps, and small compressors, the 1900/65A provides continuous oversight with minimal setup. It accepts up to four vibration channels (accelerometer or velocity) and two temperature channels (RTD or thermocouple). The 172323-01 configuration may feature specific sensor compatibility or relay output assignments, making it a drop‑in replacement for many existing installations.

Key Features

• Comprehensive Monitoring: Measures vibration velocity or acceleration, and temperature from RTDs/thermocouples.

• Adjustable Alarms: Two independent alarms per channel with selectable logic (AND/OR) for voting schemes.

• Relay Outputs: Four heavy‑duty relays (SPDT) rated 5 A at 250 VAC for direct control of annunciators or shutdown devices.

• Analog Outputs: 4‑20 mA outputs for each channel, isolated and scalable, for connection to PLCs or recorders.

• Local Display: Front‑panel LEDs indicate power, channel OK, and alarm status.

• Rugged Design: Wide operating temperature range and high immunity to electrical noise.

• Simple Configuration: Internal DIP switches and jumpers allow on‑site customization without software.

Technical Specifications

• Power Supply: 24 VDC (nominal) or 100‑240 VAC (depending on ordering).

• Vibration Inputs: 0‑10 V peak, frequency 2 Hz to 10 kHz, IEPE sensor power provided.

• Temperature Inputs: Pt100 RTD (2/3/4 wire) or thermocouple types J, K, T.

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

• Operating Temperature: -20°C to +70°C.

• Enclosure Rating: IP20 (panel mount), optional NEMA 4X enclosure.

Applications

The 1900/65A 172323-01 is widely used in industries such as water treatment, HVAC, mining, and food processing. It protects critical auxiliary equipment, reduces unexpected downtime, and provides early warning of mechanical degradation. Its compact size and flexible mounting options make it suitable for both new installations and retrofits.

Installation and Use

The monitor is housed in a durable metal case that can be panel‑mounted or installed in a standard electrical cabinet. All connections are made via pluggable terminal blocks. Configuration is achieved by setting DIP switches and adjusting potentiometers for alarm thresholds. The unit requires no special software, making it accessible to plant electricians and technicians.

In summary, the BENTLY 1900/65A 172323-01 general purpose equipment monitor delivers reliable, cost‑effective protection for a broad range of machinery, helping maintain operational efficiency and extending asset life.
