Honeywell TC-OAV081 Experion Process I/O Analog Output Module
The Honeywell TC-OAV081 is an 8-channel isolated analog output module engineered for Honeywell DCS platforms, including Experion Process I/O systems. It provides high-precision signal output across eight independent channels, supporting both voltage and current configurations to interface with control valves, actuators, and variable-frequency drives in industrial automation networks.
Output Characteristics and Signal Protection
Each channel delivers configured outputs of -10.4 V to +10.4 V or 0 to 21 mA with a 25 ms update rate across all channels. Built-in electronic protection limits output currents to 21 mA or less during open or short circuits, while maintaining overvoltage protection up to 24 VAC/VDC at room temperature. High-voltage isolation tested at 2,550 VDC between user terminals and system logic prevents common-mode noise propagation across field wiring.
