M General Overview
SKF Multilog On
-Line System IMx-M 1 - 7
User Manual
– Each relay module has 32 relays (28 SPDT and four DPDT), hence up to 96
relays in total with up to three RLM
– All relays are placed upon relay modules except for circuit fault and disarmed
relays which are placed upon protection module.
– All relays upon relay modules are user configurable.
•
Condition monitoring module and protection module pair ("CMM + PRM" or "CMM +
PRM slot")
– Up to four pairs of a condition monitoring module and a protection module
– Analog channels
o
Each CMM + PRM slot has 16 analog signal inputs
o
Up to 64 analog signal inputs in total when having four CMM + PRM slots
o
The dynamic signal inputs are configurable for a wide variety of sensors.
Signals, such as acceleration, velocity and displacement or other
parameters are easily adopted. Each input can also be configured for
standard accelerometers, 4–20 mA or ±23 V.
o
Several measurement points may be attached to one channel and both AC
and DC measurements can be measured on the same channel
– Digital channels
o
Each CMM + PRM slot has eight digital channels
o
Up to 32 digital channels in total when having four CMM + PRM slots
o
Digital channels are available for measuring speed, trigger or digital status;
for example, indicating when a measurement can take place
IMx-M System Main Parts
•
Machine protection part for the safety related functions which consists of
protection modules and relay modules.
•
Condition monitoring part for early fault detection (non-safety related functions)
which consists of condition monitoring modules.
•
Power supply units are a common part for both machine protection and condition
monitoring.
IMx-M's Unique Features
•
Individual conditions for alert and danger may be set for each measurement point.
•
Each channel has indicators for alert and danger. However, it is also possible to
manually bypass the alert and danger functionality.
• The rack is offering remote reset of latching alert/danger conditions.
•
All channels are fully computed in parallel, both condition monitoring and machine
protection.
