The C-IB-1800M is a module on a CIB bus; it has 14 binary inputs, which can be configured in the mode of the balanced loop evaluation (for ESS detectors), and 4 universal AI/DI inputs, any of which can be adjusted to one of the following ranges: a binary input, single balanced loop, a double balanced loop, an analogue input for a passive temperature sensor, a pulse input (pulse counters - power meters).

 

The C-IB-1800M module is implemented into a 4M box on a DIN rail. It is equipped with a 12 VDC power supply to power the connected intrusion (ESS) detectors. The module can be powered from a CIB or from an external 24 VDC power supply (saving the CIB load).

 

Powering

If you connect an external 24 V power supply to the A3 and A4 terminals, the power supply will by automatically switched from the internal 12 V supply (the output is on terminals A5 and A6) on the CIB to this external supply. To switch the power supply, a higher voltage than 19.2 VDC must be brought to the A3 terminal.

 

 

External 24 VDC power supply (the A3 terminal)

19.2 ÷ 30 VDC

Maximum consumption from the external 24VDC power supply connected to the A3 terminal.

230 mA

The 12 VDC power output (the A5 terminal)

11 ÷ 12.5 VDC

Maximum consumption with CIB power supply (the A3 terminal is not connected).

150 mA

Maximum consumption with a 24 VDC external source power supply connected to the A3 terminal.

Notes:

  1. The module can be powered from a CIB bus or from an external 24 V (or 27 VDC) power supply.

  2. The 12 VDC output is available for powering the ESS detectors connected to the alarm module. If the module is powered from the CIB bus, the 12 V output can be loaded with a max. of 150 mA current; if there is an external power supply (the A3 and A4 terminals), it is possible to consume up to 250 mA from the 12 V output.

  3. The supply voltage applied to the A3 and A4 terminals must be at least 19 V, then the module will automatically switch to this power supply and disconnect the powering from the CIB bus.

  4. The AI/DI1 to AI/DI4 inputs can be configured as analogue (for direct connection of temperature sensors Pt1000, Ni1000, NTC 12k, KTY81-121, a resistor up to 160 kΩ) or pulse (the input is equipped with a pulse meter) - a connection of electricity meters, water meters, etc., or balanced inputs for ESS, and also as simple binary inputs (connecting a contact input).

  5. The DI5 to DI18 inputs can be configured as simple binary inputs (for connecting contact inputs) or balanced (single and double) inputs for connecting the ESS detectors.

Notes:

  1. The C and D connectors have the same internal circuitry as the B connector.

  2. Powering of the module, including the 12 V output level, is automatically switched according to the presence of supply voltage at the A3 terminal; for a detailed description powering the module, see the beginning of this chapter.
