SMARTTEH LPC-2.A05 Longo Programmable Controller Analog Input Output Module User Manual

To measure the thermistor’s temperature, set the appropriate
reference voltage for the analog output (VAO) and measure the
voltage at the input (VAI). Refer to the module output schematic
for details.

The series resistance value (RS) is 3950 ohms, and the maximum
voltage analog input is 1.00V.

The output reference voltage is set based on the selected
thermistor type and desired temperature.

Longo programmable controller LPC-2.A05
2 DESCRIPTION
The LPC-2.A05 is a universal analog module offering a variety of analog input and output options. Each input channel can be individually configured for the following: analog voltage input, analog current input, or thermistor input dedicated for temperature measurement using thermistors (NTC, Pt100, Pt1000, etc.). Input/Output channels offer even greater flexibility, allowing configuration as: analog voltage output, analog current output, thermistor input, or PWM output, which generates a digital pulse signal with a variable duty cycle (e.g. motor control or dimming LEDs). Functionality for each channel is selected by according physical jumper on the PCB and by the configuration register. LPC-2.A05 is controlled and powered from the main module (e.g. LPC-2.MU1, LPC-2.MC9) via the Right internal bus.

4 OPERATION
LPC-2.A05 module can be controlled from the main PLC module (e.g. LPC-2.MC9). Module parameters can be read or written via Smarteh IDE software. LPC-2.A05 module can also be controlled by the Modbus RTU Slave main module (e.g. LPC-2.MU1).

4.1 Operation description

Types of inputs I1..I8 according to the jumper position

Thermistor input jumper position 1-2

To measure the thermistor’s temperature, set the appropriate reference voltage for the analog

output (VAO) and measure the voltage at the input (VAI), refer to Figure 2 for the module output schematic. The series resistance value (RS) is 3950 ohms and maximum voltage analog input is 1,00 V. Based on these data, the connected thermistor’s resistance (RTH) can be calculated. The

output reference voltage is set based on the selected thermistor type and desired temperature

range. This ensures the input voltage stays below 1.0 V while maintaining sufficient resolution. The

recommended reference voltage values for accurate measurement of the given thermistors across

their entire temperature range are listed below.

All connections, module attachments and assembling must be done while module is not connected to the main power supply.

Mounting instructions: 1. Switch OFF main power supply. 2. Mount LPC-2.A05 module to the provided place inside an electrical panel (DIN EN50022-35 rail mounting). 3. Mount other LPC-2 modules (if required). Mount each module to the DIN rail first, then attach modules together through K1 and K2 connectors. 4. Connect input and output wires according to the connection scheme in Figure 2. 5. Switch ON main power supply.
Dismount in reverse order. For mounting/dismounting modules to/from DIN rail a free space of at least one module must be left on the DIN rail. NOTE: LPC-2 main module should be powered separately from other electrical appliances connected to LPC-2 system. Signal wires must be installed separately from power and high voltage wires in accordance with general industry electrical installation standard.
