Reliable AC Output Control with the ASB804116

This discrete output module provides 16 AC channels for driving various industrial loads. The ASB804116 operates with a nominal output voltage of 115 VAC at 50 or 60 Hz. It organizes its 16 outputs into two isolated groups of 8 channels each. Each output point delivers a continuous current of 2 A for consistent load control. Additionally, the module handles surge currents up to 50 A for one cycle, accommodating inrush demands. The ASB804116 uses a screw-type terminal connector for secure and reliable field wiring.

Technical Specifications and Physical Characteristics

The ASB804116 responds to output commands within 8.3 ms at 60 Hz for timely actuation. It exhibits a voltage drop of only 1.5 V at 2 A, minimizing power loss across the outputs. The module draws 76 mA from the +5 V bus and 480 mA from the +4.3 V supply for its internal operation. It maintains a maximum OFF leakage current of 3 mA at 115 VAC for safe disconnection. The ASB804116 measures approximately 44 mm in width, 190 mm in height, and 115 mm in depth. It weighs roughly 0.54 kg, fitting standard Modicon 800 series racks. The module’s IP20 rating suits it for installation within protected control cabinets.

Installation and Application Guidance

This module interfaces directly with AC actuators like relays, contactors, and solenoid valves. First, disconnect the main power supply before inserting the ASB804116 into the backplane. Then, connect the field wiring to the screw terminal block for dependable connections. For inductive loads, always install suitable suppression devices across the load terminals. These components protect the output circuits from harmful voltage transients. Furthermore, distribute the connected loads evenly across both groups to avoid exceeding the 6 A group limit. The ASB804116 complies with IEC 61131-2 standards for assured industrial reliability.
