ALR121-S53 Yokogawa Communication Module | New & Original StockYokogawa ALR121 S53 CENTUM Series Serial Communication Module The Yokogawa ALR121 S53, also cataloged as the ALR121 Serial Communication Module, operates as a dedicated hardware component for serial data translation between the Field Control Station (FCS) and subsystems within CENTUM VP, CS3000, and ProSafe RS FIO platforms. Hardware Specifications Parameter Specification Model ALR121 S53 Brand Yokogawa Origin Japan Weight 0. 34 kg Dimensions Standard

Maintenance personnel can replace a faulty unit without powering down the Safety Manager SC or interrupting the execution of other safety-critical loops

ensuring that a single power supply failure does not result in a loss of field device power

operates as a dedicated hardware component for binary switching execution within Experion Process Knowledge System (PKS) Series C architecture networks

125 VAC field-wiring-to-backplane

reducing cabinet complexity and decreasing points of failure in vibration-prone turbine halls

Superior Noise Immunity: With a common mode rejection ratio of >130dB

3 dB per fiber link Connector Type ST-type (plastic or ceramic) Indicators Channel 1 Status (Green)

Yokogawa certifies the AAR181-S50 for use in both CENTUM VP control and ProSafe-RS safety systems

Chassis Grounding: The panel mount installation requires a low-impedance ground wire connection from the dedicated ground stud on the rear housing directly to the main plant earth ground grid
