ATC Diversified Iso-120-Abe replacement part, isolated switch 3 channel non-latching, ATC isolated switch industrial control

ATC Diversified Isolated Switch (ISO/ISL series) a UL-listed intrinsically safe control device for hazardous locations. Allows safe, reliable control of electrical loads from hazardous area control signals by limiting input circuit energy below the ignition threshold of flammable or combustible gases preventing explosions while transmitting control signals between hazardous and safe areas.

⚠ Installation Note

Installation in or near hazardous locations must comply with all applicable electrical codes and area classification requirements. Consult a qualified electrical engineer before specifying intrinsically safe equipment for a hazardous location application.

🔍 Application & Benefits

✖ Problems It Solves

  • ✖ Need to transmit control signals from a hazardous area to a safe-area load
  • ✖ Control wiring from hazardous locations requires intrinsic safety barriers
  • ✖ Compliance required with UL913 or hazardous area electrical codes
  • ✖ High-voltage isolation needed between input and output circuits to prevent fault propagation

✓ Key Benefits

  • ✓ UL913-listed intrinsically safe design limits energy in hazardous area input circuits
  • ✓ Up to 2,500V isolation between input and output circuits
  • ✓ Prevents ignition of flammable gases from electrical faults in input circuit
  • ✓ ISO series: non-latching (output follows input state)
  • ✓ ISL series: latching (output holds state until released by control signal)
  • ✓ Multi-channel models (2, 3, or 4 channel) monitor multiple hazardous area inputs

🔧 Installation Overview

  1. Install ISO/ISL relay in safe-area control panel DIN rail mount
  2. Verify the hazardous area classification and confirm ISO/ISL is rated for that classification
  3. Connect hazardous area switch or sensor wiring to ISO/ISL input terminals
  4. Wire ISO/ISL output contacts to safe-area load or control circuit
  5. Verify isolation voltage meets application requirements
  6. Test function by actuating hazardous area switch and confirming output response

❓ Common Questions

Q: What is the difference between ISO (non-latching) and ISL (latching) models?

A: ISO non-latching models operate like a standard relay the output follows the input state directly. When the input switch is closed, the output is on; when the input opens, the output turns off. ISL latching models hold a specific output state after the input is removed useful for alarm functions where the fault condition must be acknowledged before the output resets.

Q: What does "intrinsically safe" mean?

A: An intrinsically safe circuit is designed so that no spark or thermal effect produced under normal or fault conditions can ignite the surrounding hazardous atmosphere. The ISO/ISL devices limit the electrical energy in the hazardous area input circuit to safe levels regardless of what faults occur on the safe-area output side.
