TC-OAV081 | Honeywell | Analog Output Module

The Honeywell TC-OAV081 is an 8-channel high-precision analog output module designed for process control and automation applications. It converts digital controller values into bipolar voltage or current signals to drive actuators, valves, and field instruments across industrial automation networks.

Output Range and Signal Conversion

The module provides eight output channels configurable for +/-10.4 V voltage ranges or 0 to 21 mA current ranges. Conversion performance features a voltage resolution of 320 uV per count and a current resolution of 650 nA per count. Calibrated accuracy at 25 deg C is better than 0.05% of range from -10.4 V to +10.4 V for voltage outputs and from 4 to 21 mA for current outputs.

Response Time and Load Capability

All eight channels feature a fast module update rate of 25 ms, achieving an output settling time of less than 2 ms to 95% of the final value under resistive loads. Load driving capabilities support greater than 2000 ohms for voltage outputs and 0 to 750 ohms for current loops.

Circuit Protection and Isolation

The TC-OAV081 includes output overvoltage protection up to 24 VAC/VDC continuous at room temperature and electronic open/short circuit protection that limits output current to 21 mA or less. Galvanic isolation between user field circuits and system backplane logic is 100% factory tested at 2550 VDC for 1 second. Field wiring interfaces via a 20-position terminal block model TC-TBNH.
