ABB S-093N

Description

Product Overview

Technical Specifications

• Device Type: Universal industrial time relay with multiple operating modes.
• Operating Modes:
  1. ON-delay: Output signal activates after a preset time following input trigger.
  2. OFF-delay: Output signal remains active for a preset time after input is disconnected.
  3. Flashing (Cyclic): Output signal alternates between “ON” and “OFF” at a preset cycle.
• Time Adjustment Range: 0.1 seconds to 100 hours, with multi-step adjustment via a front-panel knob (ranges: 0.1–1s, 1–10s, 0.1–1min, 1–10min, 0.1–1h, 1–10h, 10–100h).
• Input Voltage: Selectable 24V DC (for PLC systems) or 110/230V AC (50/60Hz, for industrial mains), chosen at the time of order.
• Output Contacts: 1 normally open (NO) contact + 1 normally closed (NC) contact; maximum current rating: 5A at 250V AC / 30V DC.
• Protection Class: IP20, suitable for installation in control cabinets or mounting panels (prevents dust ingress and accidental contact).
• Operating Temperature Range: -25°C to +55°C (stable performance in low-temperature workshops or near heat-generating equipment).
• Time Accuracy: ±5% of the set time (within 0–55°C), meeting the precision needs of most industrial timing tasks.
• Mounting Dimensions: 22.5mm (W) × 78mm (H) × 58mm (D), designed for 1-module DIN rail mounting to save cabinet space.

Advantages and Features

1. Versatile Operating Modes: The three core modes (ON-delay, OFF-delay, cyclic) make ABB S-093N adaptable to diverse tasks. For example, it can use “ON-delay” to start a lubrication pump 5 seconds after a machine powers on (avoiding dry friction) or “cyclic mode” to flash warning lights on a conveyor (alerting workers to moving loads)—no need for specialized timing devices.
2. Ease of Use: The mechanical knob with clear scale markings allows for quick time setting in seconds, no software or complex programming required. On-site maintenance staff with basic automation knowledge can operate ABB S-093N effortlessly, reducing commissioning time and training costs.
3. High Reliability and Durability: Its simplified electromechanical design (minimizing complex chips) and UL94 V-0 flame-retardant housing ensure ABB S-093N has a mean time between failures (MTBF) of over 10 years. It maintains stable performance even in dusty environments or under voltage fluctuations common in industrial settings.
4. Broad Compatibility: Supporting both 24V DC and 110/230V AC input voltages, ABB S-093N works seamlessly with mainstream PLCs (e.g., ABB AC500, Siemens S7-1200) and actuators (solenoid valves, small motors, indicator lights). No additional adapters are needed, simplifying system integration.

Industry Application Cases

• Machinery Manufacturing: A heavy-duty machine tool manufacturer integrated ABB S-093N into CNC lathes, setting it to “OFF-delay” mode (30 seconds). After the lathe stops, the cooling pump continues running for 30 seconds to fully cool the tool and workpiece, preventing thermal deformation and extending tool life by 15%.
• Logistics and Conveying: In an automated warehouse’s conveyor system, ABB S-093N operates in “cyclic mode” (1-second cycle), making end-of-line warning lights flash alternately. This alerts sorters to incoming goods, increasing sorting efficiency by 8% and reducing operational errors by 20%.
• Food Processing: A canning plant used ABB S-093N in its cleaning line, configuring “ON-delay” mode (10 seconds). The spray valve activates 10 seconds after a can enters the cleaning station, avoiding can displacement caused by sudden high water pressure. This improved cleaning pass rates from 92% to 99%.

Comparison with Competitors

Selection Recommendations and Precautions

Selection Recommendations

1. Confirm Input Voltage: For PLC integration (e.g., ABB AC500), choose the 24V DC version of ABB S-093N; for direct industrial mains connection, select 110/230V AC to avoid extra power modules.
2. Match Load Requirements: The output contacts of ABB S-093N handle a maximum current of 5A. For loads exceeding 5A (e.g., high-power motors), use an additional contactor to prevent contact burnout.
3. Allow Time Margin: When setting timing parameters, reserve a 10–20% margin (e.g., set 6 seconds for a 5-second required delay) to compensate for voltage fluctuations or temperature-induced timing deviations.

Precautions

1. Installation Protection: With an IP20 rating, ABB S-093N must be installed in a sealed control cabinet—do not expose it to damp or dusty environments, as moisture or metal particles can damage internal components.
2. Wiring Safety: Distinguish between input and output terminals clearly. For the 24V DC version, ensure correct polarity (reverse polarity may burn internal circuits).
3. Adjustment Under Power Off: Only adjust the time knob when the device is powered off. Adjusting under power can cause accidental contact activation or electric shock hazards.
4. Regular Inspection: Check ABB S-093N every 6 months for loose terminals or stuck knobs, ensuring long-term stable operation.
