Yokogawa ARS55M-310 is a 32-channel solid-state DC output board for CENTUM digital I/O. The -3 execution switches 5 to 60 V DC loads, the -1 code identifies DIN-rail mounting and the pressure-clamp terminal keeps the field connection within the same board assembly.
Controller output states reach Yokogawa ARS55M-310 through ADV551 with ATD5A or ADV561 and the AKB331/AKB337 cable path. Each channel drives a solid-state switching circuit, while the external field supply provides the energy for the connected load.
The allowable current of Yokogawa ARS55M-310 changes with ambient temperature, so cabinet temperature and simultaneous channel loading are considered together. Inductive loads above the documented condition require the stated external suppression instead of relying on the board alone.
