Core Parameters & Value Realization

Architecture: 2-out-of-3 (2oo3) Voting Hardware Logic

Eliminates costly false shutdowns while ensuring failsafe protection.

If a single speed sensor fails, gets dirty, or takes a voltage spike, your plant keeps running seamlessly because the other two channels override the error. It completely wipes out the multi-million-dollar loss of accidental emergency plant shutdowns without ever compromising safety.

Input Voltage: 88-132 Vac / 90-150 Vdc Dual Compatibility

Guarantees seamless drop-in integration without extra electrical costs.

This specific tolerance allows the module to run natively on standard industrial 120V plant grids, absorbing volatile voltage drops and spikes common during heavy equipment startups. You save money by eliminating the need for external power transformers or dedicated power conditioners.

Response Time: ≤ 40 Milliseconds

Prevents catastrophic, fatal mechanical explosions during runaways.

Large gas and steam turbines can accelerate to destructive speeds in fractions of a second if a massive electrical load drops. A 40ms trip time ensures the fuel or steam valves slam shut instantly, keeping the physical asset intact and fully protecting your on-site engineering team from severe injury.

Engineer's Note

"When retrofitting legacy turbine control cabinets, our field engineering team highly recommends verifying your existing trip solenoid configuration before installing the 8200-203. Because this is a de-energize-to-trip model, your emergency shutdown valves must be configured to open the circuit to dump hydraulic fluid pressure. If your legacy system relies on an energize-to-trip mechanism, you will need to source the sister model (8200-204) or interpose an external safety relay to invert the logic."

Frequently Asked Questions

Can we test individual speed sensors while the turbine is actively running online?

Yes. The 8200-203 features a built-in internal frequency generator designed for online testing. Operators can safely inject a simulated overspeed test signal into Channel A, B, or C individually. The other two channels remain live and fully vigilant, ensuring the machine stays protected during maintenance without requiring a system outage.

What happens to the system if the 120V main control power experiences a complete blackout?

Because the 8200-203 uses a de-energize-to-trip fail-safe design, the internal safety relays are continuously held closed by electrical current during normal operation. A complete loss of control power instantly drops the relays, opening the trip circuit and forcing an immediate, safe mechanical shutdown to prevent unmonitored operation.

Does this module require specialized software tools to reprogram speed trip points on-site?

No external software or proprietary hand-held programmers are needed. The unit is built with three independent, front-facing LCD windows and dedicated tactile touchpads. All trip frequencies, overspeed limits, and test parameters can be configured directly on the hardware inside the key-locked, tamper-proof NEMA 4X housing.
