Detailed description

Yokogawa Mechanical Relay Board ARM55D

Manufacturer: Yokogawa Electric Corporation

Yokogawa Mechanical Relay Board ARM55D

32 Dry Contact Outputs (M4 Terminals)

The Relay Board is used in FIO subsystem of CENTUM VP. Relay input/ output boards are connected in between digital input/output modules (for FIO) and field devices. Relay input boards receive contact signals or voltage input signals of field devices. Yokogawa Mechanical Relay Board ARM55D Relay output boards receive output signals of the digital output module and amplify by the relay, and then output to field devices. These relay boards support dual- redundant digital input/output modules (for FIO). Yokogawa Mechanical Relay Board ARM55D

*1: Two sets of relay board (ARM55D, ARM55W, ARM55T, or ARM55C) and two sets of signal cable (AKB337) are required for one ADV561.

*2: For inductive loads, connect a spark killer (CR network for AC; diode for DC) in parallel with loads.

*3: For DC, 30 V or less is the requirement for the Safety Standard.

*4: ARM55C is out of scope of the Safety Standards.

*5: The applicable size of solderless lug is described below.
