D1072
- SIL 2 Temperature Signal Converter, Duplicator, Adder/Subtractor
G.M. International ISM0018-13
Non-incendive field wiring is not recognized by the Canadian Electrical Code, installation is permitted in the US only.
For installation of the unit in a Class I, Division 2 or Class I, Zone 2 location, the wiring between the control equipment and the D1072 associated apparatus shall be accomplished
via conduit connections or another acceptable Division 2, Zone 2 wiring method according to the NEC and the CEC.
Not to be connected to control equipment that uses or generates more than 250 Vrms or Vdc with respect to earth ground.
D1072 series must be installed, operated and maintained only by qualified personnel, in accordance to the relevant national/international installation standards
(e.g. IEC/EN60079-14 Electrical apparatus for explosive gas atmospheres - Part 14: Electrical installations in hazardous areas (other than mines), BS 5345 Pt4, VDE 165,
ANSI/ISA RP12.06.01 Installation of Intrinsically Safe System for Hazardous (Classified) Locations, National Electrical Code NEC ANSI/ NFPA 70 Section 504 and 505,
Canadian Electrical Code CEC) following the established installation rules, particular care shall be given to segregation and clear identification of I.S. conductors from non I.S. ones.
De-energize power source (turn off power supply voltage) before plug or unplug the terminal blocks when installed in Hazardous Area/Hazardous Locations or
unless area is known to be nonhazardous.
Warning: substitution of components may impair Intrinsic Safety and suitability for Division 2, Zone 2.
Explosion Hazard: to prevent ignition of flammable or combustible atmospheres, disconnect power before servicing or unless area is known to be nonhazardous.
Failure to properly installation or use of the equipment may risk to damage the unit or severe personal injury.
The unit cannot be repaired by the end user and must be returned to the manufacturer or his authorized representative.
Any unauthorized modification must be avoided.
Warning
D1072 series are isolated Intrinsically Safe Associated Apparatus installed into standard EN50022 T35 DIN Rail located in Safe Area/ Non Hazardous Locations or Zone 2, Group IIC,
Temperature Classification T4, Class I, Division 2, Groups A, B, C, D, Temperature Code T4 and Class I, Zone 2, Group IIC, IIB, IIA Temperature Code T4 Hazardous Area/Hazardous
Locations (according to EN/IEC60079-15, FM Class No. 3611, CSA-C22.2 No. 213-M1987, CSA-E60079-15) within the specified operating temperature limits Tamb -20 to +60 °C,
and connected to equipment with a maximum limit for AC power supply Um of 250 Vrms.
Operation
Input channel of D1072 accepts a signal from Hazardous Area/Hazardous Locations (thermocouple, resistance thermometer, transmitting potentiometer) and converts the signal to a
0/4-20 mA or 0/1-5 V or 0/2-10 V floating output to drive a load in Safe Area/Non Hazardous Locations. Presence of supply power is displayed by a green signaling LED, integrity of field
sensor and connecting line can be monitored by a configurable burnout circuit which, if enabled, can drive output signal to upscale or downscale limit.
Burnout detection is also signaled by a red LED on the front panel and by an optocoupled transistor in common with power supply. Type D1072S has a single input and output channel,
type D1072D has double input and output channel; type D1072D can also be programmed to interface a single input and obtain dual output channel (duplicator) or configurable output
channel (outputs can repeat the corresponding inputs or be proportional to the sum or difference of the two input process variables or with low/high selector function).
