*1: CP471 runs with CENTUM VP R6.05 or later version of Control Function for Field Control Station. CP471 can be combined with the style code S3 or later of ESB bus coupler module EC401. See GS 33J60E30-01EN.
*2: Select the option code “/MRN” if A2FV50 with marine standards is required. Combination of the suffix code “-A” and the option code is inhibit.
*3: Shipped with CP461. Also CP471 is usable. Replacement from CP461 to CP471 is prohibited to perform by a user.
Replacement work must be done by the service engineer authorized by Yokogawa Electric Corporation. CP471 can be combined with the style code S3 or later of ESB bus coupler module EC401. See GS 33J60E30-01EN.
*4: To meet the safety standards and EMC standards, the unit must be installed in a keyed metallic cabinet.
*5: Select the option code “/ATDOC” to follow the ATEX Directive when any of N-IO components are used for explosion protection.
