Product Description

The Rosemount 1056 is a widely used, intelligent, four-wire, dual-input liquid analytical transmitter. It is designed to provide high-performance, multi-parameter measurement for various industrial, commercial, and municipal water applications.

Below is the detailed information for the Rosemount 1056-03-21-32-AN configuration.

• Model: Rosemount 1056
• Configuration: 1056-03-21-32-AN
  • 03: Power Supply (84-265V AC, 50/60 Hz with 4 alarm relays)
  • 21: Measurement Input 1 (pH/ORP/ISE)
  • 32: Measurement Input 2 (Conductivity)
  • AN: Communication/Output (4-20 mA current loops, no digital comms specified in this base model string, typically standard analog)

Product Parameters

• Measurement Inputs: Dual-channel (supports independent measurement of pH/ORP and Conductivity simultaneously).
• Display: Large, monochromatic graphic liquid crystal display (128 x 96 pixels) with backlight.
• Enclosure Rating: Polycarbonate, NEMA 4X / IP65 (suitable for harsh, wet environments).
• Power: 84–265V AC.
• Outputs: 4-20 mA analog outputs (typically configurable) + 4 mechanical alarm relays.
• Mounting: 1/2 DIN panel/pipe/wall mounting capability.
• Dimensions: Overall 155 x 155 x 131 mm (6.10 x 6.10 x 5.15 in).

Product Advantages

1. Flexibility: Modular design allows for field-replaceable signal input boards, making configuration changes easy.
2. Cost Efficiency: Dual-sensor input reduces the cost per loop and saves significant panel space.
3. Ease of Use: Features “Quick Start” programming, which walks the user through the configuration process upon the first power-up.
4. Reliability: Robust, industrial-grade construction (IP65/NEMA 4X) ensures performance in challenging environments.
5. Versatility: Compatible with a wide range of Rosemount sensors, including pH, ORP, Conductivity, Chlorine, Ozone, and Dissolved Oxygen sensors.

Product Applications

• Water & Wastewater Treatment: Monitoring pH, conductivity, and disinfection levels in municipal and industrial plants.
• Power Generation: Cooling water management and water chemistry analysis.
• Chemical Processing: Process control for chemical concentration and neutralization.
• Food & Beverage: Quality control and sanitation monitoring.
• Pharmaceutical: High-purity water monitoring.

Precautions

• Qualified Personnel: Only qualified personnel should perform installation, operation, programming, and maintenance.
• Electrical Safety: Ensure the instrument is correctly grounded through a three-wire power source. Disconnect all power before opening the enclosure.
• Wiring: Signal wiring must be rated for at least 240V. Use appropriate cable strain reliefs; non-metallic strain reliefs do not provide grounding, so use grounding-type bushings if necessary.
• Environment: Ensure that unused conduit openings are sealed with appropriate NEMA 4X or IP65 plugs to maintain the integrity of the enclosure.
• Operation: Do not operate the device with the front panel or case open. Always verify that the configuration matches the installed sensors before starting the process measurement.
• Calibration: Regularly calibrate the sensors according to the specific application requirements to ensure accurate readings.
