High-Density 4-20 mA Analog Output Control

The TC-0AH06I analog output provides eight high-density current output channels for precise control of process actuators and instruments. This analog output features fixed 4-20 mA outputs, making it ideal for applications requiring consistent loop-powered signals. The eight-channel design significantly reduces the number of modules needed for large-scale control systems.

The module achieves an outstanding accuracy of ±0.05% of full scale at 25°C, ensuring reliable performance for demanding process control loops. The temperature drift of only ±25 ppm/°C maintains this precision across varying ambient conditions. A fast 500 µs settling time enables rapid response in dynamic applications, such as control valve positioning and variable speed drive regulation.

Integrated Loop Power and Comprehensive Protection

This analog output includes internal loop power for all eight channels, eliminating the need for external 24 VDC supplies. The TC-0AH06I provides 1500 VAC isolation between individual output channels, eliminating ground loop issues and improving overall signal integrity. This channel-to-channel isolation proves essential when connecting multiple field devices operating at different reference potentials.

The module features comprehensive protection, including short-circuit protection and over-voltage protection on every channel. These safeguards prevent module damage from accidental wiring faults or field device failures. The outputs drive loads up to 600 Ω per channel, accommodating most standard 4-20 mA field instruments.

Physical Design and Status Indication

This analog output occupies a single slot in the Experion 13-slot chassis and measures 45 mm in width. The module weighs 0.28 kg, making handling easy during installation and replacement procedures. A 34-point removable screw terminal block on the front panel accepts all field wiring connections, simplifying both installation and ongoing maintenance.

Eight green LEDs provide clear visual status indication, with one LED per output channel showing normal operation. This comprehensive indicator set enables rapid troubleshooting without requiring a programming terminal. The terminal block accepts wires up to 2.5 mm² (AWG 14), ensuring secure and reliable connections.

Power and Environmental Specifications

The TC-0AH06I draws 320 mA from the 5 VDC backplane, ensuring stable operation in fully populated racks. This analog output operates reliably across a temperature range of 0°C to +60°C. It also withstands humidity from 5% to 95% (non-condensing) and resists vibration up to 2G at 10-150 Hz, making it suitable for demanding industrial environments.
