Overview of the Yokogawa ADM55R Relay Output Module

The ADM55R serves as a relay output module within Yokogawa’s industrial control architecture. This unit switches external loads through isolated relay contacts for dependable process control. Engineers rely on it across manufacturing plants that demand precise ON/OFF actuation.

Key Technical Specifications of the ADM55R

The ADM55R combines robust relay hardware with straightforward field wiring. Below you will find the core parameters that define this module’s performance envelope.

Physical Design and Interface Details

The ADM55R adopts a compact footprint that fits standard Yokogawa I/O racks. Its dimensions measure 130 mm in length, 100 mm in width, and 25 mm in depth. Moreover, the module weighs roughly 280 grams, which simplifies rack installation and field replacement. The backplane bus connector ensures fast communication with the host controller.

Performance and Switching Capabilities

Each ADM55R module provides sixteen independent relay output channels for flexible load control. Optical isolation separates field wiring from internal logic, therefore protecting sensitive control circuitry. The contacts handle 2 A at 250 V AC or 30 V DC for demanding loads. Consequently, the module suits solenoid valves, indicators, and small motor starters.

Power and Environmental Considerations

The ADM55R operates on a 24 V DC nominal power supply. Power consumption remains approximately 4.5 W during normal operation. The operating temperature range spans 0°C to 55°C for industrial environments. Storage temperature extends from -20°C to 70°C. Furthermore, humidity tolerance reaches 95% RH without condensation.
