YOKOGAWA ARM15A 32 Dry Contact Inputs (M4 Terminals)
YOKOGAWA Relay Boards (for FIO):
ARM15A, ARM55D, ARM55W, ARM55T, ARM55C, ARS15B, ARS15M, ARS55M
GENERAL
This document describes the specifications of relay board 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. 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).
