D6048
- SIL 3 Digital Output Driver, NE Loads, Loop Powered
G.M. International ISM0413-0
D6048S must be installed, operated and maintained only by qualified personnel, in accordance to the relevant national/international installation standards.
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
Operation
The single channel Loop Powered Digital Output Isolator, D6048S, is suitable for driving solenoid valves, visual or audible alarms to alert a plant operator, or other process control
devices from a driving signal. It can also be used as a controllable supply to power measuring or process control equipment. Its use is allowed in applications requiring up to SIL 3 level
(according to IEC 61508) in safety related systems for high risk industries. The Safety PLC or DCS driving signal powers the field device through the D6048S, which provides isolation
and is capable of monitoring the conditions of the line. Short and open circuit diagnostic monitoring, dip-switch selectable and active when input power is present, provides LED indication
and NC transistor output signaling. When fault is detected output is de-energized until normal condition is restored. Line short and open output circuit fault detection is also reflected on
the PLC / DCS input circuit providing less than 10 mA consumption. An override input, dip-switch selectable, is provided to permit a safety system to override the control signal.
When enabled, a low input voltage always de-energizes the field device regardless of the input signal. Three basic output circuits are selectable, with different parameters, to interface
the majority of devices on the market. The selection among the three output characteristics is obtained by connecting the field device to a different terminal block.
Presence of output, as well as integrity or fault condition of device and connecting line are displayed by signaling LEDs (yellow for status, red for fault).
Start-up
Before powering the unit check that all wires are properly connected and verify their polarity. Check conductors for exposed wires that could touch each other causing dangerous
unwanted shorts. Activate control input, the status led must be in accordance with condition of the corresponding input line.
Installation
D6048S is a Digital Output Driver housed in a plastic enclosure suitable for installation on T35 DIN-Rail according to EN50022, with or without Power Bus or on customized Termination
Board. D6048S unit can be mounted with any orientation over the entire ambient temperature range.
Electrical connection of conductors up to 2.5 mm² are accommodated by polarized plug-in removable screw terminal blocks which can be plugged in/out into a powered unit without
suffering or causing any damage.
The wiring cables have to be proportionate in base to the current and the length of the cable.
On the section “Function Diagram” and enclosure side a block diagram identifies all connections.
Identify the function and location of each connection terminal using the wiring diagram on the corresponding section, as an example:
Connect positive input at terminal “1” and negative input at “2”.
Connect positive transistor fault output at terminal “3” and negative at “4”.
Connect positive input override at terminal “5” and negative input at “6”.
Connect positive output A for solenoid valve at terminal “7” and negative at “10” or output B at terminal “8” and negative at “10” or output C at terminal “9” and negative at “10”.
Connect SPST fault output transistors checking the load rating to be within the maximum rating (100 mA at 35 Vdc (
≤
1.5 V voltage drop)).
Units must be protected against dirt, dust, extreme mechanical (e.g. vibration, impact and shock) and thermal stress, and casual contacts.
If enclosure needs to be cleaned use only a cloth lightly moistened by a mixture of detergent in water.
Any penetration of cleaning liquid must be avoided to prevent damage to the unit. Any unauthorized card modification must be avoided.
