Part Number：ARM55W-000 S1

The YOKOGAWA ARM55W-000 S1 is a relay board used in various industrial control applications. This relay board is designed to provide relay outputs for controlling external devices and equipment based on signals from a control system.

Purpose: Provides relay outputs for switching external devices such as alarms, actuators, and other equipment based on control signals from a DCS or PLC.

Number of Relays: Typically equipped with 8 or 16 relays. 

Relay Contacts: Usually comes with SPDT (Single Pole Double Throw) or other types of relay contacts.

Voltage Rating: Commonly rated for 24 VDC, 120 VAC, or 240 VAC. 

Current Rating: Typically supports up to 2 A to 5 A per relay contact. 

Input Type: Receives control signals from the DCS or PLC.

Communication: Connects to the control system via standard interfaces (e.g., digital inputs, communication bus).

Power Supply: Operates from a power supply required for the relay board, usually specified in the datasheet (e.g., 24 VDC or 110/220 VAC).

Isolation: Provides electrical isolation between the relay contacts and the control circuitry to prevent interference and protect the system.

Operating Temperature: Typically operates within a temperature range of 0°C to 60°C (32°F to 140°F). 

Product type：Relay Board

Condition：100% Original
