Communication interface CH2, using optional submodules

The output from the CH2 communication interface is located on the terminal block C or D, depending on the basic module type. The layout of signals in the terminals is available in several variants, in accordance with the basic module type:

Fig. 1 for the basic modules CP-1000 -1001 and CP-1091

Fig. 2 for the basic module CP-1003

Fig. 3 for the basic modules CP-10x4, CP-10x5.

Fig. 4 for the basic modules CP-10x6, CP-10x8.

The CH2 interface is not fitted with any submodule as a standard. The customer can choose - depending on the required interface (RS-232, RS-485, CAN, M-bus, etc.) an appropriate submodule and fit it in a free position/slot within the module (the procedure how to fit the submodule is described in the manual) TXV 004 10.

Notes:

1. The descriptions on the terminals correspond to the two most common submodules - the RS-232 and the RS-485 interfaces; in other submodule variants the significance of terminals is naturally different - see the description on the specific submodule.

2. The terminal block is galvanically isolated from all circuits of the basic module. When a submodule with galvanic isolation is fitted, its inputs and outputs lead to the D connector and are galvanically isolated from other circuits of the basic module (the signal ground of the galvanically isolated interface is marked GNDS).

Notes:

1. The descriptions on the terminals correspond to the RS-485 interface; in other submodule variants the significance of terminals is naturally different - see the description of the specific submodule.

2. The terminal block is galvanically isolated from all circuits of the basic module. When a submodule with galvanic isolation is fitted, its inputs and outputs lead to the D connector and are galvanically isolated from other circuits of the basic module (signal ground of the galvanically isolated interface is marked GNDS).

Notes:

1. The older variants of the basic modules were fitted with fixed terminal blocks, but the numbering and the significance of all terminals is the same.

2. The descriptions on the terminals correspond to the two most common submodules - the RS-232 and the RS-485 interfaces; in other submodule variants the significance of terminals is naturally different - see the description on the specific submodule.

3. The terminal block is galvanically isolated from all circuits of the basic module. When a submodule with galvanic isolation is fitted, its inputs and outputs terminated on the C connector are galvanically isolated from other circuits of the basic module (the signal ground of the galvanically isolated interface is marked GNDS).

Notes:

1. The CH2 interface in these basic modules is only terminated on D1 to D5 terminals (the descriptions on the box again describe the signals for RS-232 and RS-485 interfaces). N.B: Some submodules have limited use, and some cannot be fitted at all in these basic modules.

2. The DO0 and DO1 outputs are terminated on D7 to D9 terminals - the SSR outputs 230 VAC, 1 A outputs are galvanically isolated from all other circuits of the basic module.

3. The terminals of the CH2 D1 up to D5 interfaces are galvanically isolated from all other circuits of the basic module. When a submodule with galvanic isolation is fitted, its inputs and outputs terminated on the C connector are galvanically isolated from other circuits of the basic module (the signal ground of the galvanically isolated interface is marked GNDS).
