Yokogawa Electric Corporation ADV551-P53 Digital Output Module

The Yokogawa ADV551-P53 Digital Output Module is a 32-channel, rack-mounted 24 VDC current-sink output module used in CENTUM and FIO DCS cabinets to transmit discrete ON/OFF control signals to field devices. Each channel delivers up to 100 mA with an output ON voltage of ≤2 VDC and OFF leakage ≤0.1 mA, and it is isolated 2 kV AC from the system; it supports ON/OFF, pulse-width, and time-proportional output, with a dual redundant configuration and an external supply range of 20.4–26.4 VDC. Applications include driving relays, solenoids, valves, and alarms in oil & gas, chemical processing, power generation, and manufacturing environments.
