Overview

The Emerson 8202-HO-IS Analog Output Module is part of the PAC8000 modular I/O family, engineered for both general-purpose and hazardous area installations. It provides eight intrinsically safe analog output channels, each capable of driving 4–20 mA signals to field devices such as I/P converters, actuators, and transmitters. Moreover, the module supports HART pass-through communication, enabling advanced diagnostics and device status reporting.

Its intrinsically safe design makes it suitable for Zone 2 / Class I Div. 2 hazardous environments, ensuring compliance with international safety standards. Engineers value its modularity and ease of integration into PAC8000 systems, while operators benefit from built-in fault detection and simplified maintenance.

Technical Data

Typical Applications

• Oil & Gas Facilities: Drives I/P converters and actuators in hazardous zones.

• Chemical Processing Plants: Provides intrinsically safe analog outputs for valves and transmitters.

• Power Generation: Controls turbine and boiler actuators with HART-enabled diagnostics.

• Water Treatment Plants: Supports distributed control of pumps and valves.

• Pharmaceuticals: Ensures safe analog output control in regulated environments.

For example, the 8202-HO-IS is often deployed in refineries and chemical plants where intrinsically safe outputs are required to control actuators while maintaining compliance with safety standards.
