Power/Data status light

The Power/Data status light is green when power is supplied,it is blinking when data is received and sent, or it is red when an error occurs or when another device is accessed on the bus.

Wellpro WP3066ADAM

The Wellpro WP3066ADAM is a data acquisition module for DS18B20 temperature sensors. Up to 8 sensors can be connected to the module.

Wellpro WP3066ADAM

Technical specifications

• Operating temperature— -20-70°C
• Power — external DC power supply 9V — 30V
• Power consumption — 2 W

Pin assignment

• AVcc — "+" power supply module
• AGnd — "-" module power
• 485A — line A RS485 (+)
• 485B — line A RS485 (+)
• Vdd — +5V for power supply to DS18B20 sensor
• Gnd — DS18B20 sensor ground
• Data1-8 — sensor data output 1 — 8 DS18B20

Modbus Registers

Storage registers (Holding registers) 0x00-0x07 contain temperature information received from the sensor. A 0xFFFF value read from the register means that the sensor is not connected.

The temperature is determined as follows:

• DATA > 10000 — temperature below 0°C, TEMP =-(DATA-10000)/10
• DATA < 10000, the measured temperature exceeds 0°C, TEMP = DATA/10

Negative temperature values are not supported by the current version of the Wirenboard template!

Wellpro WP9038ADAM

The WP9038ADAM I / o module has 4 digital inputs, 4 digital outputs and 6 analog inputs.

Wellpro WP9038ADAM

Technical parameters

• Analog inputs — 0-20 ± 2 mA DC
• Digital inputs — active level low
• Digital outputs — NPN-open collector transistor output, 500mA
• Operating temperature— -20-70°C
• Power supply — 9-30 V DC
• Power consumption — 2 W

Pin assignment

• AVcc — "+" power supply module
• AGnd — "-" module power
• 485A — line A RS485 (+)
• 485B — line A RS485 (+)
• DI_1-4 — digital inputs
• DO_1-4 — digital outputs
• AI_1-6+ — positive analog inputs
• Gnd is the signal ground for analog inputs.

The analog outputs allow three — wire sensors to be connected- in this case the sensor is connected to the Gnd and the sensor power supply - " + " sensor to the sensor power supply "+" and the signal wire to the AI_x+terminal. When two-wire connection Gnd is connected to the "-" of the power source sensor, and the sensor is connected to the "+" power source of the sensor and the output AI_x+

The digital outputs are protected by a diode and allow switching of relays or indicators connected to the DO_x and "+" pin of the main power supply.

The digital inputs are galvanically isolated via the optocoupler; a button or switch is connected to the DIx pin and the "-" main power supply of the module.

Modbus registers

• Holding registers 0x00-0x05 contain the values of the analog signal being read. The current in milliamperes is calculated by the formula I = (DATA*20)/4095.
• Discrete input registers (Discrete Input registers) 0x00-0x03 allow you to read the status of digital di inputs.
• Registers flags (Coil registers) 0x00-0x03 enable write/read status of digital outputs DO.

Power/Data status light

The Power/Data status light is green when power is supplied,it is blinking when data is received and sent, or it is red when an error occurs or when another device is accessed on the bus.

The red lights DI 1-4 (four to the left) indicate the presence of a logical 1 at the corresponding digital input and DO 1-4 (four

to the right) lights - at the corresponding digital output.

Wellpro WP8028ADAM

The WP8028ADAM I/O module has 8 digital inputs and 8 digital outputs.

Technical parameters

• Digital inputs — active level low
• Digital outputs — NPN-open collector transistor output, 500mA
• Operating temperature— -20-70°C
• Power supply — 9-30 V DC
• Power consumption — 2 W

Назначение выводов

• AVcc — "+" питания модуля
• AGnd — "-" питания модуля
• 485А — линия А RS485 (+)
• 485B — линия А RS485 (+)
• DI_01-8 — цифровые входы
• DO_01-8 — цифровые выходы

Цифровые выходы защищены диодом и позволяют коммутировать реле или индикаторы, подключенные к выводу DO и "+" основного источника питания.

Цифровые входы гальванически развязаны через оптрон; кнопка или выключатель подключаются к выводу DIx и "-" основного источника питания модуля.

Регистры Modbus

• Регистры дискретных входов (Discrete Input registers) 0x00-0x07 позволяют считывать состояние цифровых входов DI.
• Регистры флагов (Coil registers) 0x00-0x07 позволяют записывать/считывать состояние цифровых выходов DO.

Индикаторы

Индикатор Power/Data светится зеленым при подаче питания, мигает при получении и отправке данных, светится красным при ошибке или обращении к другому устройству на шине.

Индикаторы красного цвета DO 1-8 показывают наличие логической единицы на соответствующем цифровом выходе, а DI 1-8 — на соответствующем цифровом входе.
