FDCI181-2 Input Module
Product Manual
Characteristic
l2 monitored digital input
lInput lines are monitored for open line and short/open circuit (terminal resistors is
mandatory)
lMicroprocessor-controlled signal evaluation
lPrevention of noise interference through intelligent analysis of input signals
lLED display of input status
lAutomatic address setting, without encoder settings or Dip-switch
lPower supply via FD18-BUS
lCommunication with controller via FD18-BUS(detection line)
lDirectly used in dry areas, Applicable in dusty and humid areas when installed in
FDCH221 housing
l“Sticker Method” easy for commissioning
Application
With the input a status can be monitored, the input can be configured by controller or
configuration tools as follows:
l“Status“input or “Alarm“input
lLead monitoring for open line or open line and short circuit
lWhen inputting status, according to different status of contact, can be set as
follows:
-Normal mode: normally open input
-Inverted mode: normally closed input

“Status” inputs and “Alarm” inputs
“Alarm“ inputs trigger an alarm as soon as the input is activated. “Status“ inputs trigger a
monitoring status change as soon as they are activated.
Line monitoring and circuitry
The input lines are monitored for open line or open/short line. To make these possible,
resistors must be properly connected to the end of lines of the input (Fig.6). When an
open line or a short line occurs on one of the input lines, a trouble message is
transmitted to the control panel.
The input must be potential-free.
Structure
The module consists of the module carrier, the printed circuit board, the cover and the
protection cover. The printed circuit board includes the LEDs. The LEDs indicate the
status of the inputs. The cover of the printed circuit board is transparent, so that the state
of the LEDs is visible even when the housing is closed.
To protect the modules from environmental influences, there are additional options for
the housing.

Preparation
Determine the type of installation: there are 2 types of
installation for FDCI181-2 Input module:
–Installation outside a switching cabinet or a control unit:
use FDCH221 housing (Fig. 3) .
–Installation directly in a switching cabinet or a control
unit: mount the module on an even surface (Fig.2).
Damage by water!
In humid or wet environments always use the housing
FDCH221!
Installation of FDCH221 Housing
1. Open the housing.
2. Determine the cable entries in the housing and break
these open.
3. Use two screws (M 4) to fit the housing on a plane
surface (Fig. 3). Distance between holes: 182.0±1.0mm.
4. Fix and guide in the cables with waterproof joint
(provided by users themselves).
5. Fix the lid additionally with four screws (Fig. 4). (Onl
y this
way is IP65 protection guaranteed.)
The housing lid is transparent. Consider a suitable
installation position to make sure that the LEDs of the
module are visible at any time.
Installation of module in FDCH221 housing
Caution!
Overheating of FDCI181-2 input module.
1. Open the housing.
2. Fix module with two screws in the housing (Fig. 3).
3. Close the housing.
Installation on an even surface
1. Position module on an even surface (Fig. 2).
2. Fix module with two M4 screws. Distance between
holes:63.5±1.0mm.
Electric connection
1. Connect the cables to the terminals according to Fig.
5/6.
Connect only one wire per terminal!
2. Connect the resistors to the end of the monitored line.
2 resistors of 3.3KΩand 2 of 680Ωare delivered with
the product.
