Description of Equipment or Protective System:
u-remote is a modular remote I/O-system that may consist of one field bus coupler and up to
64 I/O-Modules, optional power-feed modules and power distribution modules. u-remote modules are
installed on a standard mounting rail. They shall be installed always in a suitable enclosure (see 17: special
conditions for safe use).

Switch- loss for digital output modules
In case of switching inductive loads with digital output modules without a clamping network,
there will be turn off losses. These losses can be calculated with the following equation:

needed to calculate the power dissipation on the bus-contacts of module n.
ISENS
is the sensor supply current.
IACT
is the actor supply current.

is the current that is drained via input path power distributions.

If module n is a power-feed module, set IIN,n to IIN_M and IOUT,n to IOUT_M given in the table for power-feed
modules.
Calculation of power dissipation
The power dissipations of a module can be calculated out of the calculated bus currents (see “Calculation of
path currents”) and the formulas for power dissipations given in the module specific tables. The total power
dissipation of a module is the sum of all stated power dissipation for that module.
The power dissipation of the u-remote station is the sum of all power dissipations of all modules.

Special conditions for safe use
1.
The remote I/O-System u-remote shall only be used in an area of not more than pollution degree 2, as
defined in IEC 60664-1.
2.
The remote I/O-System u-remote shall be installed in an enclosure that provides a degree of
protectionnot less than IP 54 in accordance with IEC 60079-15.
3.
When the temperature under rated conditions exceeds 70 °C at the cable or conduit entry
point, or 80 °C at the branching point of the conductors, the temperature specification of the
selected cable shall be in compliance with the actual measured temperature values.
4.
The ambient temperature range -20 °C to +60 °C shall not be exceeded.
5.
For UR20-4RO-CO-255 (Relay Module) only:
a.) Device shall be installed in an environment free of condensation, corrosives and conducting
dusts.
b.) If the switching voltage exceeds 63V, a transient protection device shall be provided that limits
the transients to a peak voltage of 500V or less.
c.) Due to the fact that relays are subject to wear, it must be ensured, by appropriate maintenance
intervals, that the temperature do not exceed the limits of temperature class T4.
Remark: A contact resistance of more than 110 mΩ will be considered as a fault.
d.) Resistive loads only
6.
If mounted in other directions than horizontal (reference mounting rail), restrictions to the max.
operating temperature, max. output currents may apply.
7.
While explosive atmosphere is present:
a.) No electrical connection shall be separated in energized condition.
b.) The USB interface shall not be used.
c.) Dip-switches, binary-switches and potentiometers shall not be actuated.
8.
Only power supplies with secure isolation shall be used.
