CP-1003

The CP-1003 basic module features eight multi-purpose inputs, each of which can be used either as an analogue input (voltage, current or a passive temperature sensor) or a binary 24 V input, with eight fast binary inputs featuring adjustable decision level, four analogue outputs ± 10 V, eight relay outputs and four high-speed transistor outputs allowing direct connection of DC or stepper motors.

The basic CP-1003 module is fitted with the Ethernet interface, with up to 4 serial ports (the first one with a fixed RS-485 interface, others with an additional slot for an optional submodule) and two TCL2 system interfaces for connecting expansion modules, which increase the number of I/O in the system.

A standard configuration of the module is in a 9M housing on a DIN rail (for the housing dimensions, see Chapter 13.2.1 9M housing on a DIN rail), and it is fitted with six removable terminal blocks.

Notes:

1. The DI0 - DI7 inputs, which can also be used as analogue inputs AI0 - AI7, are galvanically isolated from the internal PLC circuits; they have a common ground with the AO0 - AO3 analogue outputs. The DI0 - DI7 inputs work as binary only when they are not used for analogue measurements (valid for each input independently of the others).

2. The DI8 - DI15 inputs can be used as inputs for counters. These inputs are arranged in two groups of four with separately terminated power supply for each galvanically isolated tetrad. Each of these four inputs can thus operate with different voltage levels in the range of 5-24 V, which makes it possible also to connect IRC sensors with 5 or 12 V power supply. Even when they are used as inputs for counters, the DI8 - DI15 inputs can be concurrently used as binary.

3. The DI8 - DI15 inputs make it possible to switch on the function of capturing short pulses. This function extends the selected level of input signal up to the PLC cycle. In this way you make sure that no single pulse shorter than the PLC cycle will be lost in the input.

4. If any of the four inputs is used for an object of the relevant counter, the function of capturing short pulses cannot be used in any of the four inputs.

Notes:

1. Conventional counters can be operated with the signal frequency of 5 kHz. In an unidirectional counter and IRC modes, the hardware support is enabled and the counter can be operated at a high speed mode with the signal frequency of up to 100 kHz.

The PWM DO8 ÷ DO11 outputs

The DO8 - DO11 binary transistor outputs can also be operated in the pulse-width modulation (PWM) mode. It is possible to set a common pulse repetition periodfor these outputs as a part of the initialization. The pulse width itself is variable and is determined separately for each output by the value of the corresponding object variable PWM output These four outputs can be blocked in pairs from the user program.

Notes:

1. The RS-485 (CH1) interface is firmly terminated in the module with appropriate impedance and it must always be at the end of the RS-485 line (the same applies for the TCL2 interface in the Foxtrot basic module).
