M-2000 series remote I/O module

The M-2000 series is a family of network data acquisition and control modules with digital or analog I/O functions. The modules can be remotely controlled through an RS-485 serial bus by using DCON and Modbus RTU/ASCII protocols. The selectable transmission speed of the RS-485 port is up to 115,200 bps. Modbus has facto standard communications protocol in industry, and is now the most commonly available means of connecting industrial electronic devices. The M-2000 series is slim-type Form Factor I/O that provides the saving space for the installation, easy wiring and distributed I/O points applications. The bias resistor and terminal resistor by switch selectable that is used to improve the communication and solve the communication fail of RS-485 network.

M-6000 series remote I/O module

The M-6000 series of distributed I/O provides a wide variety of input, output, and smart control solutions, all of which are based on a single universal hardware platform. The M-6000 series combines inputs and outputs, saving your time and space when both are at a premium. Since M-6000 series feature both inputs and outputs on the same board, retailers can reduce the space requirement for I/O boards by as much as 50%! Traditional I/O board schemes required retail operators to mount separate input and output boards within an enclosure, increasing the time and cost to mount the boards. The M-6000 I/O boards are communications devices needed to connect to the facility management system to control refrigeration, HVAC and lighting systems.

tM series

The tM series is a family of network data acquisition and control modules, providing digital I/O functions. The modules can be remotely controlled through an RS-485 serial bus by using DCON and Modbus RTU protocols. The selectable transmission speed of the RS-485 port is up to 115,200 bps. Modbus has become a de facto standard communications protocol in industry, and is now the most commonly available means of connecting industrial electronic devices. This makes the tM series perfect integration with the HMI, SCADA, PLC and other software systems.

The functionality of the tM series is the same as the M-7000 series. The tM series tiny RS-485 I/O modules support various I/O types, like photo-isolated digital input, relay contact, photoMOS relay, and open-collector output.

The tM series provides dual watchdog: module watchdog and host watchdog. The module watchdog is designed to automatically reset the microprocessor when the module hangs. The host watchdog monitors the host controller (PC or PLC), and the output of the module can go to predefined safe value state when the host fails.

For maximum space savings, the tM series is offered in an amazing tiny form-factor that makes it can be easily installed in anywhere, even directly embedded into a machine. It is equipped with two removable terminal block connectors for easy wiring.

Features

• Cost-effective remote I/O modules
• Supports Modbus RTU and DCON protocols
• Isolated Digital Input and Output
• RS-485 bus supports baud rate up to 115200 bps
• Dual-watchdog with power-on and safe value
• Terminal block connector for easy wiring
• Tiny form-factor and low power consumption
• RoHs compliant with no Halogen
• Made from fire retardant materials (UL94-V0 Level)
• Easy DIN-Rail mounting

IO Expansion Unit

DCON Based I/O Expansion Unit

DCON protocol is a request/reply communication protocol for the I-7000/8000/87K series I/O modules. It defines a simple ASCII format protocol, like $AAN, $AASi6, #AAN, .., etc.

Modbus Based I/O Expansion Unit

Modbus is very wide known protocol in the industrial manufacturing and environment monitoring fields. It is suit master-slave or query-response distributed I/O applications. The unit is pre-installed a Modbus firmware.

Therefore PC, HMI or PLC can use Modbus/TCP and Modbus/RTU protocol to communicate with I/O modules in the unit via the RS-232/485 or Ethernet interface.Besides the slave I/O functionality, it is also a c language based programmable controller that equipped a DOS-like OS (MiniOS7). Users can use C compilers that can create 16 bit executable file (*.exe) to develop a program then download it to the controller. That let the controller work stand alone.

There are two free charge version compilers (Turbo C 2.0 and Turbo C++ 1.01), we suggest users to use the Turbo C++ 1.01.

Using the software development toolkits that we provide can customize the firmware. The SDK provides rich functions for Modbus communication, such as Modbus/TCP master/slave, Modbus/RTU master/salve, Modbus/ASCII master, etc.
