Customer connections for contact i/omodule optionCAuTIONEquipment damage. Do not drill connection holes intothe top of the cabinet. Connection holes in the topof the cabinet will allow moisture to seep into thecontrol and damage the components or cause controlmisoperation. Failure to comply will void the control’sfactory warranty. T249.0The Contact I/O module (Figure 19) permits connection ofcontact-type input devices (switches, relays) and indicatingdevices (relays, LEDs, lamps) to the Form 4D control toeffect local Contact input/output (I/O). The Contact I/Omodule accessory is used for supplementing normal localcontrols and status indicators for Contact I/O functions. Thefirst optional Contact I/O module inputs and outputs arefactory-set and are shown in Figure 20.Additional I/O modules require customer configuration toassign functionality for each contact input or output — viathe ProView NXG software configurable logic tool. Refer toService Information S280-104-2 Form 4D Microprocessor-Based Recloser Control Programming Guide for additionalinformation.IMPORTANTThe control gives priority to TCC timing and issuing atrip signal rather than changing the status of a ContactI/O module output or responding to a Contact I/Omodule input. Refer to Table 4 for I/O response times.The Contact I/O module for the first I/O card containsfour factory-set inputs and four outputs for Contact I/Ofunctions. Each Form 4D control can accommodate up tofour Contact I/O modules.Whetting voltage is supplied from TB1 for the Contact I/Oinputs terminal block on the back panel as shown in Figure 20.Two of the Contact I/O outputs are Form A relay contactsand two are Form C relay contacts. All four outputs are ofnon-latching type. Refer to Table 5 Output Ratings for outputfusing recommendations.otee:N Latching is defined as an output that retains itsstatus when control power is removed.Non-latching is defined as an output that returns to adefault status when control power is removed.otee:N Following a firmware upgrade the Contact I/Omodule output relays will revert to the de-energizedstate. Additionally, the Contact I/O module may needto be remapped.NOTICEExternal leads must be shielded and the shield mustbe grounded at both ends. Terminate each lead witha 320 vAC, 150 Joules metal oxide resistor (MOv), orequivalent, at the remote end. Attach MOvs betweenthe leads and ground. Failure to properly shield andprotect leads can result in equipment damage and/orunintentional operation.Figure 19.
