Description
Engineered for seamless integration within Honeywell control systems, the TC-OAV081 serves as a high-precision analog output interface. This module provides reliable digital-to-analog conversion to drive final control elements such as control valves, actuators, and variable speed drives. Utilizing eight independent channels, it supports both voltage and current output configurations to accommodate diverse field device requirements.
The TC-OAV081 is designed to maintain signal integrity in demanding industrial environments, featuring robust open and short-circuit electronic protection alongside continuous overvoltage safety features. Its modular form factor ensures straightforward installation and maintenance within standard system chassis layouts.
Features
- Eight independent analog output channels.
- Dual-mode support for voltage (±10.4 V) and current (0 to 21 mA) signals.
- Continuous output overvoltage protection up to 24 VAC/VDC at room temperature.
- Electronic current limiting protection for short and open circuits.
- High-resolution digital-to-analog conversion for precise process control.
Applications
- Modulating control valve and actuator positioning.

Installation Guidelines
Ensure the control system chassis is powered down before inserting or removing the TC-OAV081 module. Secure the module firmly into its slot and verify that the front-facing latch is engaged. When wiring the TC-TBNH 20-position terminal block, maintain separation between low-voltage analog signal lines and high-voltage power cables to prevent electromagnetic interference. Properly ground all cable shields at the designated chassis grounding point.
