Indicates a potentially or imminently hazardous situation which, if not avoided, could result in death or serious injury.


Indicates a potentially hazardous situation that may result in minor or moderate injury.

1 Do not use wire gauge other than 0.08 to 1.5 mm2 (28 to 16 AWG), unless wires can be isolated from mains power and relay circuits.

Precautionary labels

NOTICE
Indicates a situation which, if not avoided, may cause damage to the instrument. Information that requires special emphasis

Read all labels and tags attached to the instrument. Personal injury or damage to the instrument could occur if not observed. A symbol on the instrument is referenced in the manual with a precautionary statement.

caution This symbol, if noted on the instrument, references the instruction manual for operation and/or safety information.
shock hazard This symbol indicates that a risk of electrical shock and/or electrocution exists.
This symbol indicates the presence of devices sensitive to Electro-static Discharge (ESD) and indicates that care must be taken to prevent damage with the equipment.

Class 1 Division 2 label

This label indicates that the module is approved for use in a Class I Div 2 A-D, T4/ Class I Zone 2 IIC, T4 environment when used with a Class I Div 2 approved SC4200c and SC4500 controllers and sensors: LDO and TSS-Ex 1.

Precautions for hazardous location installation


Explosion hazard. Only qualified personnel should conduct the installation tasks described in this section of the manual. This equipment is suitable for use in Class 1, Division 2, Groups A, B, C & D Hazardous Locations with specified sensors and options appropriately certified and rated for Class I, Division 2, Group A, B, C & D, Zone 2, Group IIC Hazardous Locations


Explosion hazard. Do not remove or replace modules while power is supplied to the controller unless there are no ignitable gases in the area.


Explosion hazard. Do not connect or disconnect electrical components or circuits to the equipment unless power has been removed or the area is known to be non-hazardous


Explosion hazard. Connect only peripheral components that are clearly marked as certified for Class 1, Division 2 Hazardous Locations


Explosion hazard. Connect only peripheral components that are clearly marked as certified for Class 1, Division 2 Hazardous Locations.

Never connect any sensor or digital or analog module to an SC Controller that is not clearly marked as certified for Class 1, Division 2 Hazardous Locations.

Product overview

The 4–20 mA output module is an expansion card that supplies five 4–20 mA analog output connections to the SC4200c and SC4500 controllers. The module connects to the expansion modules slots inside the controller. The analog outputs are commonly used for analog signaling or to control other external devices.

Installation


Multiple hazards. Only qualified personnel must conduct the tasks described in this section of the document.


Electrocution hazard. Remove power from the instrument before this procedure is started.


Electrocution hazard. High voltage wiring for the controller is conducted behind the high voltage barrier in the controller enclosure. The barrier must remain in place unless a qualified installation technician is installing wiring for power, alarms, or relays.


Electrical shock hazard. Externally connected equipment must have an applicable country safety standard assessment.

NOTICE
Make sure that the equipment is connected to the instrument in accordance with local, regional and national requirements.

Electrostatic discharge considerations

NOTICE
Potential Instrument Damage. Delicate internal electronic components can be damaged by static electricity, resulting in degraded performance or eventual failure

Refer to the steps in this procedure to prevent ESD damage to the instrument:

  • Touch an earth-grounded metal surface such as the chassis of an instrument, a metal conduit orpipe to discharge static electricity from the body.
  • Avoid excessive movement. Transport static-sensitive components in anti-static containers orpackages.
  • Wear a wrist strap connected by a wire to earth ground.
  • Work in a static-safe area with anti-static floor pads and work bench pads.

Install the unit

Install the module in the controller. Refer to the illustrated steps that follow.

Notes:

  • To keep the enclosure rating, make sure that all unused electrical access holes are sealed with anaccess hole cover.
  • To maintain the enclosure rating of the instrument, unused cable glands must be plugged.
  • Maximum loop resistance is 500 Ω.
  • The analog outputs are isolated from the other electronics, but are not isolated from each other.
  • The analog outputs are self-powered. Do not connect to a load with voltage that is independentlyapplied.
  • The analog outputs cannot be used to supply power to a 2-wire (loop-powered) transmitter.

NOTICE
Use cabling with a wire gauge of 0.08 to 1.5 mm2 (28 to 16 AWG)2 and an insulation rating of 300 VAC or higher. Use twisted-pair shielded wire3.

2 Do not use wire gauge other than 0.08 to 1.5 mm 2 (28 to 16 AWG), unless wires can be isolated from mains power and relay circuits.
3 Use of non-shielded cable may result in radio frequency emission or susceptibility levels higher than allowed.
