IMPORTANT SAFETY CONSIDERATIONS
It is very important for the user to consider the possible adverse
effects of power, wiring, component, sensor, or software failures
in designing any type of control or monitoring system. This is
especially important where economic property loss or human life
is involved. It is important that the user employ satisfactory
overall system design. It is agreed between the Buyer and
Acromag, that this is the Buyer's responsibility.

Notes (Table 1):
1. Consult the factory for current information on agency (e.g.
Canadian Standards Association, etc.) approvals.
2. Unit can be ordered with or without factory calibration; if unit
is factory calibrated to a customer’s specifications, the model
number suffix “-C” will indicate this. Any customer specified
calibration information will be included on a separate
calibration label on the unit.
DESCRIPTION:
The Series 550L is a member of the Acromag SmartPack
family. It converts four independent DC voltage inputs into
corresponding network variables. The nominal input range for
each input is fixed at -10V to +10VDC, or -100V to +100VDC.
Through network variables, virtually any part of the input range
can be scaled to output values in the range of -100% to +100%,
as defined by the SNVT_lev_percent network variable type. For
example, a 0 to 5 V input can be scaled to output 0 to 100%. Or
a -75 to +75 V input can be scaled to output -100 to +100%. For
each analog input, network variable updates may occur due to
changes in input level and/or at specified time intervals.
All SmartPack modules are designed for harsh industrial
environments. They feature RFI and EMI protection, a wide
operating temperature range, and isolation between power,
network and I/O. They are DC powered, DIN-rail mountable, and
available with either a twisted pair (TP/XF-78) or free topology
(TP/FT-10) transceiver. Up to 64 modules can be connected on
a single network segment. Multiple segments may be connected
using repeaters to increase the number of modules and distance.
