C-JC-0201B, a module for blinds control

The C-JC-0201B module is equipped with one output intended for standard blinds control - i.e. the so-called three-point-control: opening-idle-closing. The module can also be used for three-point valve control, etc. The module is internally equipped with 2 relays with a fixed connection for blinds control via terminated 100mm long insulated wires. Continuous current on each output is 16 A, see detailed information about the relays used). The module is in a plastic box in the version for the flush box (built-in design).

The module is suitable for switching 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 output of the blinds. This enables a local function of blinds control (the DI1 input controls the DO1u output, the DI2 input controls the DO1d 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.100mm, terminated with a pressed-on sleeve without a collar.

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