HIMA F30 03 98 2200496 Signal Isolator

Product Dimensions：

Here is a detailed product overview of the HIMA Signal Isolator (typically part of the HIMA HIMax or HIQUAD safety systems, or specific HART-compatible isolation modules).

## Product Overview: HIMA Signal Isolator

HIMA signal isolators are high-performance safety components designed to provide galvanic isolation between field devices and the safety controller. They ensure that electrical interference, ground loops, or high-voltage transients in the field do not damage the Safety Instrumented System (SIS) or compromise the integrity of the safety loop.

## Technical Specifications (General Parameters)

While specific parameters vary by model (e.g., the HIMA HiZ series or modules for HIMax), typical specifications include:

## Key Advantages

• Maximum Safety: Certified for use in SIL 3 loops, ensuring the highest level of functional safety.

• Galvanic Isolation: Effectively eliminates ground loops and protects the controller from surges originating in the field.

• HART Compatibility: Supports bi-directional communication for smart field devices, allowing for remote calibration and diagnostics.

• High Density: Slim housing designs allow for more channels per DIN rail, saving cabinet space.

• Fault Detection: Includes features like line fault monitoring (LFM) to detect short circuits or wire breaks in the field.

## Safety Precautions & Installation Notes

• Wiring Integrity: Ensure that “Safe” and “Unsafe” wiring is physically separated according to local electrical codes to prevent induction.

• Environmental Protection: Must be installed in an enclosure with at least IP54 protection if used in dusty or humid industrial environments.

• Load Matching: Verify that the input impedance of the isolator matches the output capability of your field sensor.

• Hot Swapping: Only perform module replacement if the specific HIMA rack/model supports “hot-plug” functionality to avoid system trips.

## Product Applications

HIMA signal isolators are used in critical infrastructure where failure is not an option:

1. Emergency Shutdown Systems (ESD): Isolating pressure and flow transmitters in oil and gas refineries.

2. Fire & Gas Systems (F&G): Connecting smoke, flame, and gas detectors to the safety logic solver.

3. Burner Management Systems (BMS): Ensuring stable signal transmission for flame scanners in high-interference environments.

4. Chemical Processing: Protecting the SIS from corrosive or volatile environments via intrinsically safe (IS) barriers.
