1715-TASOF8 8-PT Analog Output Termination | Allen-Bradley

Allen-Bradley 1715-TASOF8 ControlLogix 8-Channel Simplex Analog Output Termination Assembly

Product Description

The Allen-Bradley 1715-TASOF8 (Part No: 1715-TASOF8) is a specialized Simplex Termination Assembly (TA) engineered for the 1715 Redundant I/O System. It serves as the vital physical wiring interface for the 1715-OF8 Analog Output module, facilitating the connection between the controller backplane and field-side actuators. As part of the ControlLogix family’s redundant architecture, this assembly is designed to maintain signal integrity in high-availability process control environments.

This termination assembly supports up to 8 channels of 0–24 mA analog outputs. The 1715-TASOF8 is designed for simplex (non-redundant wiring) configurations, providing a direct, reliable path for current signals to reach field devices such as control valves and variable speed drives. Its construction includes mechanical keying to prevent the accidental insertion of incorrect I/O modules, ensuring system safety and reducing the risk of hardware damage during maintenance or commissioning.
