Installation2604 Controller2.4.4. I/O ModulesThe 2604 controller contains five positions in which 4-terminal I/O modules can be fitted.These positions are marked Module 1, Module 3, Module 4, Module 5, Module 6, in Figure 2-3. Module 2 is reserved for the Memory Module which can only be fitted in this position. Tofind out which modules are fitted check the ordering code which is found on a label on theside of the instrument.Any module, listed in this section, can be fitted in any position, except the PV input - limitedto positions 3 and 6 only; and the Analogue Input module - cannot be fitted in slot 5. Careshould be taken, therefore, to ensure that modules are fitted as expected from the order code.The instrument can be interrogated in ‘View Config’ level to locate the positions in which themodules are fitted. See Chapter 4, Access Levels. If modules have been added, removed orchanged it is recommended that this is recorded on the instrument code label.I/O ModuleRelay (2 pin)andDual Relaymax264Vac, 2A,min12V, 100mATypicalusageHeating,cooling,alarm,programevent,valve raise,valve lowerH/WCodeConnections and examples of useNote: The order code and terminal number is pre-fixed by the module number.Module 1 is connected to terminals 1A, 1B, 1C, 1D; module 3 to 3A, 3B, 3C, 3D, etc.First relayContactorR2RelayAandPanel lampRRetcBContactorRelayPanel lampetcVoltagesupplyCDSecond relay(dual relay only)Change OverRelaymax264Vac, 2A,min12V, 10mAHeating,cooling,alarm,programevent, valveraise, valvelowerR4ContactorRelayPanel lampetcVoltagesupplyABCDIsolatedSingle LogicOutput18Vdc at24mA maxHeating,Cooling,ProgrameventsLOSSR orthyristorunit+-Output ACommon+_ABCD+_2-18 User Guide Part No HA026491 Issue 3.0 Apr-02
