High-Density DC Switching Without Moving Parts

This board provides 32 solid-state relay outputs for demanding DC load applications. It handles frequent switching operations without contact wear or mechanical fatigue. Many facilities choose this module for its exceptional reliability and silent performance. The unit delivers consistent output control across a wide range of industrial processes.

Technical Specifications

Channel Configuration and Output Topology

This module packs 32 solid-state outputs into a single wide-format board. Each channel uses a MOSFET switching element with normally open configuration. The board divides outputs into four isolated banks of eight channels each. This bank isolation simplifies wiring for loads with different voltage references.

Power Requirements and Thermal Efficiency

The unit consumes only 8 W when all 32 outputs remain active. On-state resistance of 0.1 Ω keeps power dissipation remarkably low. Reduced heat generation extends the life of surrounding cabinet components. The board requires minimal cooling for reliable operation.

Switching Performance and Dynamic Response

Turn-on time reaches under 1 millisecond for fast output actuation. Turn-off responds in just 0.5 milliseconds for precise control. The module supports continuous switching frequencies up to 1 kHz. This high-speed capability makes the board suitable for pulse-width modulation tasks.

Mechanical Design and Physical Attributes

This board measures 250 mm wide with a total weight of 1.15 kg. Four ribbon cable connectors provide flexible interfacing with termination panels. The 50 mm height allows installation in standard Yokogawa rack systems. DIN rail mounting becomes possible with an optional adapter accessory.

Diagnostic Indication and Channel Monitoring

Thirty-two LEDs provide instant visual feedback for each output channel. An illuminated LED indicates the channel is in a conducting state. Operators can quickly identify failed outputs without diagnostic tools. This visibility streamlines maintenance and reduces system downtime.

Surge Handling and Leakage Performance

Each output withstands surge currents of 6 A for up to 10 milliseconds. This surge capability accommodates capacitive loads and incandescent lamps. Off-state leakage current remains below 10 µA at rated voltage. This low leakage prevents false triggering of sensitive loads.

Isolation Architecture and Noise Rejection

Bank-to-bank isolation reaches 1,500 V AC for robust noise immunity. This high isolation prevents cross-channel interference in mixed-voltage applications. The design minimizes ground loop effects for stable operation. This architecture enhances system reliability in electrically noisy environments.

Safety Certifications

The ARS55M holds CE, UL, and CSA certifications for worldwide acceptance. These approvals validate the module’s compliance with stringent safety standards. Each board undergoes comprehensive testing before dispatch. This quality assurance delivers confidence in long-term field service.
