Modbus RTU Products

Modbus RTU Products

Modbus RTU data acquisition products are offered by DGH Corporation. These products contain a serial port, either RS232 or RS485 and are compatible with all popular commercial software programs that support the Modbus RTU protocol. See individual product details below.

The D1000M provide direct connection to a wide variety of sensors to any host with an RS232 or RS485 port. The modules perform all signal conditioning, scaling, linearization, and A/D conversion. They measure analog signals such as: voltages, currents such as 4-20mA, thermocouples, RTDs, thermistors, load cells, frequency signals and are easily mounted on DIN-Rails using the MK-1 mounting kit.

The D1000M also contain discrete I/O bits to control solid-state relays and sense the position of relay contacts. The discrete outputs are open-collector transistors that can use with a wide variety of relays and control annunciators.

The D5000M provide direct connection to four analog signals of the same type and range to any host with an RS-232 or RS-485 port. The modules perform all signal conditioning, scaling, linearization and conversion to engineering units. They measure analog signals such as: voltages, currents such as 4-20mA, thermocouples, thermistor signals and are easily mounted on DIN-Rails using the MK-1 mounting kit..

The DIN rail mounted DIN-100 modules convert analog input signals to digital data and transmit via RS-485 to a controller which may be a computer or other processor-based equipment. They measure analog signals such as: voltages, currents such as 4-20mA, thermocouples, RTDs, thermistors, load cells and frequency signals.

The DIN-100 series also contain modules for discrete I/O bits to control solid-state relays and sense the position of relay contacts. The discrete outputs are open-collector transistors that can use with a wide variety of relays and control annunciators.

The DGH 1700M series provide computer monitoring and control of devices through solid-state relays or TTL signals. The status of digital inputs and outputs is communicated to the host in either Modbus RTU or DGH ASCII format using RS232 or RS485 serial communications. The 1700M series includes:

You can string up to 247 boards/modules on one twisted pair of wires using RS485 and repeaters in Modbus RTU format. When using RS232 in Modbus format you can use one board/module per serial port. The 1700M series allows a single computer to monitor and control thousands of I/O points. The 1700M series is compatible with all industry standard I/O relay modules and mounting boards.
