Siemens FDCIO221 1 input/output module addressed 12-33V DC S54312-F2-A1
Siemens FDCIO221 module with 1 input and 1 output addressed, line control and potential-free relay. Ideal for technical alarm activation and device control, with the following features:
-
Input: 1 potential-free contact (NO/NC)
-
Relay output: AC 22 V, 2 A / DC 30 V, 2 A (potential-free)
-
Communication protocol: FDnet / C-NET
-
Power supply: 12 - 33 VDC
-
Quiescent current: Max. 0.4 mA
-
Dimensions: 95x71x23 mm (WxHxD)
Compact Input/Output Module for Intelligent Fire Systems.
Addressable 1 input and 1 output module for fire systems on FDnet or C-NET loops, used to monitor and control technical devices or alarms in a decentralized manner.
With its compact size and versatile configuration, it integrates easily into professional fire systems, making it ideal for managing fire doors, fans, sprinkler systems, technical or status signaling.
Monitored Input for Technical Signals or Alarms
The module includes a digital input for NO/NC contacts, monitored for:
-
Line interruptions
-
Short circuits
With the terminal resistors provided, you can configure the behavior of the contact directly from the fire panel, choosing whether to send status messages or alarm activations.
Configurable Relay Output
The output can be used in two modes:
Unmonitored potential-free relay:
-
AC 22 V, 2 A (max 44 VA)
-
DC 30 V, 2 A (max 60 W)
Monitored (requires DC 24 V auxiliary power supply):
-
DC 30 V, 2 A
The output is ideal for direct control of technical devices, such as:
-
Signaling devices (sirens, flashing lights)
-
HVAC systems
-
Control units for elevators
-
Motors for automatic shutters and openers
Simple and Reliable Installation
-
Built-in line separator
-
Automatic address assignment at system startup
-
Transparent enclosure for Led visibility
-
Quick mounting on DIN rail (TS35) or in optional FDCH221 enclosure for IP65 protection
-
Power supply and communication over standard two-wire cable
