Ex relevant specificationsCI/TZIDC/110/120-EN TZIDC, TZIDC-110, TZIDC-120 417.1.5 IECEx nElectrical dataSignal circuit(terminal +11 / -12)U = 9.7 V DCI = 4 ... 20 mA, max. 21.5 mAContact input(terminal +81 / -82)U = 12 ... 24 V DC; 4 mASwitch output(terminal +83 / -84)U = 11 V DCThe following modules may be operated with the TZIDC as an option:Plug-in module for digital position feedback(terminal +51 / -52 or +41 / -42)U = 5 ... 11 V DCPlug-in module for analog position feedback(terminal +31 / -32)U = 10 ... 30 V DCI = 4 ... 20 mA, max. 21.5 mAPlug-in module for shutdown contact input(terminal +51 / -52 or +85 / -86)U = 20 ... 30 V DCMechanical digital feedback(terminal limit1 +51 / -52 or limit2 +41 / -42)U = 5 ... 11 V DCSpecial conditions• Devices may only be connected to circuits in zone 2 if they are suitable for operation in zone2 potentially explosive atmospheres and for the conditions prevailing at the installationlocation (manufacturer's declaration or certificate from an inspection authority).• For the "digital feedback with proximity switches" circuit, external measures must beimplemented to prevent the rated voltage from being exceeded by more than 40 % in theevent of transient disturbances.• It is only permissible to connect, disconnect, and switch live circuits during installation ormaintenance, or for the purpose of carrying out repairs. Comment: It is considered veryunlikely that a potentially explosive atmosphere would be present in zone 2 at the same timethat installation or maintenance/repair work was being carried out.• Only non-flammable gases may be used for the pneumatic auxiliary power.• Only use suitable cable entries which meet the requirements of IEC 60079-15.• If the SJ2_S1N (NO) proximity switch is used, the positioner may only be operated at anambient temperature range from -25 ... 85 °C.7.1.6 CSA InternationalCertificate: 1052414Class 2258 02 PROCESS CONTROL EQUIPMENT –For Hazardous LocationsClass 2258 04 PROCESS CONTROL EQUIPMENT –Intrinsically Safe, Entity – For HazardousLocationsClass I, Div 2, Groups A, B, C and D;Class II, Div 2, Groups E, F, and G,Class III, Enclosure Type 4X:
