Figure 23. Contact Input Label TextA Label Text: Enter a string of up to 64 alphanumeric characters.See Terminals and Connectors for an illustration of the programmable input terminals.Contact OutputsBESTCOMSPlus® Navigation Path: Settings Explorer, Programmable Outputs, Contact OutputsHMI Navigation Path: Not available through HMI.DECS-250 contact outputs consist of a dedicated watchdog output and 11 programmable outputs. Anadditional 18 contact outputs are available with the optional Contact Expansion Module (CEM-2020H).The optional CEM-2020 provides an additional 24 contact outputs. Contact Basler Electric for orderinginformation.Watchdog OutputThis SPDT (Form C) output changes state during the following conditions:• Control power is lost• Normal firmware execution ceases• Transfer Watchdog Trip is asserted in BESTlogicPlus.Watchdog output connections are made at terminals WTCHD1 (normally open), WTCHD (common), andWTCHD2 (normally closed).Programmable OutputsThe 11 programmable, normally-open contact outputs can be configured to annunciate DECS-250 status,active alarms, active protection functions, and active limiter functions. Using BESTlogicPlusprogrammable logic, these outputs can be used as part of a user-configured logic scheme to control andannunciate a variety of system conditions and contingencies. Information about using the programmableoutputs in a logic scheme is provided in BESTlogicPlus Programmable Logic.To make the programmable contact outputs easier to identify, you can assign a custom nameA thatrelates to the functions of your system. Figure 24 shows the BESTCOMSPlus Contact Outputs screenwhere each of the 12 outputs can be assigned a custom name.CALL US TODAY1-888-POWER-58REQUEST A QUOTEparts@genpowerusa.comSHOP ONLINEwww.genpowerusa.comCALL US TODAY1-888-POWER-58REQUEST A QUOTEparts@genpowerusa.comSHOP ONLINEwww.genpowerusa.com
