C-LC-0202B, a module for lighting control

The C-LC-0202B module is equipped with 2 relays with a switching contact; each is separately terminated by approx. 100mm long insulated wires. Continuous current in each output is 16 A, inrush current up to 800 A ( max. for 200 μs) – see more detailed information on the relays used).). The module is in a plastic box in the version for the flush box (built-in design).

The module is designed to switch the capacitive (electronic power supplies for LED lamps, switching power supplies, etc.) and inductive loads.

The module is also equipped with two binary inputs, which are served during normal operation as standard binary inputs, but if the module is powered and there is no communication (the system is not programmed yet, or it is faulty), the inputs control directly the relay outputs. This enables the local function of the one-touch control of lighting (the DI1 input controls the DO1 output, the DI2 input controls the DO2 output).

The module is powered directly from the CIB bus.

Notes:

1. The isolation voltage between the outputs and Internal circuits is 4,000 VAC.

2. The isolation voltage among groups is 4,000 VAC.

3. Inductive load is dealt with (if necessary) by an external element: an RC member, a varistor, a diode (DC), see the Chapter Interference suppression, application of interference suppression elements.

4. The relay outputs are terminated by insulated wires (black) with a stranded core with the cross-section of 1.5 mm² (CYA 1.5), the length approx.100 mm, terminated with a pressed-on sleeve without a collar.

5. The CIB and both universal inputs are terminated on the terminal block.
