Emerson Ovation 3A99168G01 Relay Output Card

3A99168G01 Advantages

The Emerson Ovation 3A99168G01 Relay Output Card offers several key advantages over comparable relay output boards.

Multi-channel relay drive circuitry. Reliable relay contact output drives multiple field devices simultaneously, which is critical for boiler-turbine interlock protection logic and process optimization in power generation units.

Flexible relay mode jumper configuration. Onboard jumpers support channel activation and relay working mode setup, eliminating the need for extra external drive conditioning hardware and simplifying cabinet-side field installation.

Simplex and TMR triple modular redundant support. The card ensures relay contact output within the Emerson Ovation DCS are not interrupted by a single-point component fault, directly supporting high-availability power plant architectures.

Conformal coated circuit protection. The conformal protective coating helps shield PCB components from moisture, dust, and minor corrosive atmospheres inside control cabinets, extending service life in harsh plant-side cabinet environments.

Wide operating temperature range of 0°C to +60°C. The Emerson Ovation 3A99168G01 Relay Output Card operates reliably in variable-temperature power plant cabinet environments without additional thermal protection.

Native Emerson Ovation DCS integration. As a factory-original Emerson Ovation component, the card integrates directly with compatible Ovation cabinet backplanes and auxiliary hardware without extra adapters or custom modification.
