Schneider 170ADO53050 Modicon Momentum 8-Channel Triac Output Module

Product Introduction

When industrial processes demand reliable switching of AC loads, the Schneider 170ADO53050 discrete output module delivers robust performance. Part of the Modicon Momentum series, this module provides 8 outputs using Triac technology, each rated for 120V AC operation. Designed for distributed control architectures, it offers a compact solution for managing solenoids, contactors, and indicator lights in manufacturing environments.

Technical Specifications Breakdown

The 170ADO53050 features 8 discrete outputs with a voltage rating of 120V AC. Each channel supports a maximum current of 2A, with a total current rating of 16A across all outputs. Short-circuit protection is provided by an internal 5A slow-blow fuse per group, while output overload protection uses another internal fuse. Surge current handling includes 10A for 2 cycles, 15A for 1 cycle, and 5A for 3 cycles, ensuring resilience against transient loads. The minimum output current is 5mA, and maximum leakage current is 1.9mA, with a voltage drop of less than 1.5V at 2A. Response time is 0.5 line cycles for both on and off transitions. Channel isolation reaches 1780V AC for 1 minute, and power dissipation is 6W typical, 7.5W maximum.

Industry Applications

This module excels in applications requiring high-current AC switching, such as packaging lines, material handling systems, and HVAC controls. For example, in a bottling plant, the 170ADO53050 can drive multiple conveyor motor contactors and solenoid valves, with its surge current capability handling inrush loads without nuisance fuse blows. The fast 0.5-cycle response time ensures precise timing in sorting and filling operations.

Installation & Setup Guidance

Mount the 170ADO53050 on a DIN rail within the Modicon Momentum backplane. Ensure the input power matches the 120V AC rating. Connect loads to the output terminals, observing the per-channel current limit of 2A and total module current of 16A. Use the internal fuse ratings (5A slow-blow per group) as a guide for external circuit protection. Verify wiring polarity and secure all connections before powering up.

Maintenance & Reliability

Periodically inspect the module for signs of overheating or loose connections. The Triac outputs have no moving parts, reducing mechanical wear. Monitor the internal fuse status; if a fuse blows, investigate the connected load for shorts before replacing. Keep the module in a clean, dry environment within its specified power dissipation limits to maximize service life.

Selection Guide & Purchasing Advice

Before ordering the 170ADO53050, confirm your system voltage is 120V AC and that your load currents do not exceed 2A per channel. Verify compatibility with your Modicon Momentum backplane and controller.
