This module has 16 digital inputs. The input voltage range is 18 to 30
volt d.c. and the input current is 6 mA at 24 V. The inputs are divided
into two individualy isolated groups with eight channels and one
voltage supervision input in each group. Every input channel
consists of current limiting components, EMC protection
components, input state indication LED and optical isolation barrier.
The process voltage supervision input give channel error signals if
the voltage disappears. The error signal can be read via the ModuleBus.
Features and benefits
• 16 channels for 24 V d.c. inputs with current sinking
• Two isolated groups of 8 with voltage supervision
• Input status indicators

The input voltage range is 18 to 30 volt dc and the input current
source is 6 mA at 24 V. The inputs are divided into two individualy
isolated groups with eight channels and one voltage supervision
input in each group. Every input channel consists of current limiting
components, EMC protection components, input state indication
LED and optical isolation barrier. The process voltage supervision
input give channel error signals if the voltage disappears. The error
signal can be read through the ModuleBus.
This includes:
Motor starter and feeder modules (all sizes), which are equipped with measuring and
communication electronic device MControl
Motor starter and feeder modules (all sizes), which are equipped with intelligent device,
UMC and M10x, communicates to MLink.
Circuit breakers connected to the switchgear communication with the interface MConnect
Circuit breakers connected to the switchgear communication with the interface MLink
Excluded from supervision in MService are all modules not connected to the internal switchgear
communication such as MSpeed (Variable Speed drives in MNS iS) and conventional modules.
Fieldbus
MLink can include Fieldbus communication to DCS. The type of Fieldbus must be selected
before ordering the MLink type. The Fieldbus specific information (PROFIBUS, MODBUS etc.)
can be found in the following documents:
