HARDWARE MODULES
All
u REG
system modules have standard external dimensions: 142.0 x 90.0 mm (width x
height).
The modules are installed in respective slots on the motherboard ( MB ). Slot arrangement
and sizes (IDC type) on the motherboard ( MB ) determine corresponding slots for the modules,
which prevents making an error. All modules are unambiguously recognized and configured by
the device, which takes place automatically in Plug & Play.
In terms of their design and functions, the modules can be divided into two groups :
1. dedicated to specific slots;
2. universal (dedicated to a range of slots).
Group 1 includes the following modules:

IF-0 / IF-1 / IF-2 / IF-4 – i nter f aces module for computer-communication purposes of the master
processor, dedicated to slot #0 ;

CT-0 – c urrent t ransformers module dedicated to slot #1 ;

VP - 0 – voltage transformers module dedicated to slot #1 ;

VT-0, VT-5 – v oltage and current t ransformers module, dedicated to slot #2 ;

VT-1, VT - 2 – double v oltage t ransformers module with a current transformer (I0), dedic. to slot #2 ;

VT-3, VT-4, VT-8 – double v oltage t ransformers module (without U0) with current transformers
(I1+I2+I3), dedicated to slot #2 ;

VT-6 – voltage transformers module, transformers of the second current s Ig, I0 (dedicated
to slot #2 );

VT-7 – module with 3 x 500 V AC voltage transformers and two full stars (If) ( dedicated to slot 2);

PS-0 / PS-1 – p ower s upply module (switching-mode power unit), equipped with inputs, outputs and
a circuit to handle alarms, dedicated to slot #3 and/or #6 ;

SS-0 – s imple s ervice module which is a simplified I/O module with an alarm support circuit (like PS
but without power unit), dedicated to slot(s) #3 and/or #6 .
Universal modules in
group 2 → dedicated to slots 3 to 6 [ 7 to 13 for versions equipped with an
expander]:

CR-0, CM-0, CI-0 – smart I/O modules (including those with power relays) and programmable
sensitivity threshold inputs;

CO-0 – module with 16 relay outputs;

IO-0 – i nput/ o utput module with digital bidirectional inputs/outputs of programmable input
resistance (220/24 V DC);

GP-0 – two-channel GPRS modem module, dedicated to slots 6 to 13 .
All
u REG
system modules (except IF-x and
GP-0
) are equipped with PhoenixContact
Combicon and/or Wieland external strips (pitch: 7.50 and 5.00 mm).
The
CO-0 module is an exception; It has 32 terminals with the pitch of 3.50 mm.
The module slots can be used together with a wide range of pins (parallel, perpendicular,
and slanted arrangement). With this solution, if necessary, the entire unit can be replaced
smoothly within interfering in terminal sheathing .
The pins can have screw or spring terminals as well as measurement slots or pins for
probes. For slots having more contacts, it is recommended to use pin stacks. The pin type and
model are specified in the purchase order.
The description of terminals in
u REG
strictly depends on hardware configuration (modules)
and logic of APPLICATION .
