2.1.1 Use of hazard information
D A N G E R
Indicates a potentially or imminently hazardous situation which, if not avoided, will result in death or
serious injury.
WARNING
Indicates a potentially or imminently hazardous situation which, if not avoided, could result in death
or serious injury.
1Do 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.
English 3

CAUTION
Indicates a potentially hazardous situation that may result in minor or moderate injury.
N O T I C E
Indicates a situation which, if not avoided, may cause damage to the instrument. Information that
requires special emphasis.
2.1.2 Precautionary labels
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.
This symbol, if noted on the instrument, references the instruction manual for operation
and/or safety information.
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.
Electrical equipment marked with this symbol may not be disposed of in European
domestic or public disposal systems. Return old or end-of-life equipment to the
manufacturer for disposal at no charge to the user.
2.1.3 Class 1 Division 2 label
CL 1 DIV 2 Gr A-D
See Manual
Voir manuel
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.
2.1.4 Precautions for hazardous location installation
D A N G E R
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.
D A N G E R
Explosion hazard. Do not remove or replace modules while power is supplied to the
controller unless there are no ignitable gases in the area.
D A N G E R
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.
4 English

D A N G E R
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.

2.3 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.
2.4 Product components
Make sure that all components have been received. Refer to Figure 1. If any items are missing or
damaged, contact the manufacturer or a sales representative immediately.

Section 3 Installation
D A N G E R
Multiple hazards. Only qualified personnel must conduct the tasks described in this
section of the document.
English 5

D A N G E R
Electrocution hazard. Remove power from the instrument before this procedure is
started.
D A N G E R
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.
WARNING
Electrical shock hazard. Externally connected equipment must have an applicable
country safety standard assessment.
N O T I C E
Make sure that the equipment is connected to the instrument in accordance with local, regional and
national requirements.
3.1 Electrostatic discharge (ESD) considerations
N O T I C E
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 or
pipe to discharge static electricity from the body.
• Avoid excessive movement. Transport static-sensitive components in anti-static containers or
packages.
• 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.
3.2 Install the module
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 an
access 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 independently
applied.
• The analog outputs cannot be used to supply power to a 2-wire (loop-powered) transmitter.

N O T I C E
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.
2Do 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.
3Use of non-shielded cable may result in radio frequency emission or susceptibility levels higher
than allowed.
