DGH D1100 Sensor to Computer Interface Voltage Input Module Series

The D1100 voltage input module is part of the DGH's D1000 sensor to computer interface data acquisition module family. This input module converts voltage input signal from the choice of six different voltage ranges (±10mV, ±100mV, ±1V, ±5V, ±10V and ±100V) and continuously converts the data using the ASCII protocol to give digital output at the rate of 8 conversions per second, storing the latest data in the buffer. The data can be retrieved by sending an ASCII command from the host computer. The D1100 voltage input module also contains one digital input/60Hz events counter (not applicable to D1100M) and two open-collector digital outputs (or HI/LO alarms) which may be controlled by the host computer and used to control, for example, solid-state relays. For extra security, it utilises a non-volatile EEPROM (Electrically Erasable Programmable Read Only Memory) to store all user-selectable settings, meaning the values are maintained in the event of power loss. The D1100 comes pre-set with default values of 300 baud, one start bit, eight data bits, one stop bit, no parity and any address recognized, but these values can be easily changed by the user. The modules are designed to be compatible with all popular computers utilising RS-232C or RS-485 ports and no software is necessary to start using them, although the utility software is provided. The D1100 can be mounted on a DIN-rail if required (MK-1 mounting kit required) and can be combined with other D1000/D2000 modules to provide complete customised data acquisition system for given application.

DGH D1500M Modbus Bridge Input Module Series

The D1500M bridge input module is part of the DGH's D1000M Modbus sensor to computer interface data acquisition module family. This input module converts the outputs from load cells, strain gauges or other bridge type sensor input signal to digital data, linearises and scales it in mV, and communicates the values using the Modbus RTU protocol to give digital output. The D1500M bridge input module also contains a digital output which may be controlled by the host computer and used to control, for example, solid-state relays. For extra security, it utilises a non-volatile EEPROM (Electrically Erasable Programmable Read Only Memory) to store all user-selectable settings, meaning the values are maintained in the event of power loss. These modules are designed to be compatible with all popular computers utilising RS-232C or RS-485 ports and no software is necessary to start using them, although the utility software is provided. Upon startup, a simple command can be used to setup desired baud rate, parity and other parameters. The D1500M can be mounted on a DIN-rail if required (MK-1 mounting kit required) and can be combined with other D1000M/D2000M modules to provide complete customised data acquisition system for given application.

DGH D1600 Sensor to Computer Interface Frequency Input Module Series

The D1600 frequency input module is part of the DGH's D1000 sensor to computer interface data acquisition module family. This input module converts the frequency or pulse sensor input signal to digital data, linearises, scales and communicates the values using the ASCII protocol to give digital output. The D1600 series includes frequency, timer, 60H events counter (20Hz available upon request) and accumulator (combination of frequency/timer with events counter) models. The D1600 frequency input module also contains a digital input (acting as the events counter on 160x and 161x modules). For extra security, it utilises a non-volatile EEPROM (Electrically Erasable Programmable Read Only Memory) to store all user-selectable settings, meaning the values are maintained in the event of power loss (this feature excludes the events counter - upon power-up the counter is set to 0). The D1600 comes pre-set with default values of 300 baud, one start bit, eight data bits, one stop bit, no parity and any address recognized, but these values can be easily changed by the user. The modules are designed to be compatible with all popular computers utilising RS-232C or RS-485 ports and no software is necessary to start using them, although the utility software is provided. The D1600 can be mounted on a DIN-rail if required (MK-1 mounting kit required) and can be combined with other D1000/D2000 modules to provide complete customised data acquisition system for given application.

DGH D1700 Digital Input/Output Module

The D1700 15-channel digital I/O-to-computer module is part of the DGH's series of modules for monitoring and control of industrial devices through solid state switches. These modules feature 7 input and 8 output bits (models D1701 and D1702) or flexibility by allowing user to define each channel as input or output (models D1711 and D1712). The digital inputs accept a wide signal level input up to +30Vdc and have TTL logic input switches. The open-collector transistor digital outputs will sink 100mA, which is ideal for controlling the solid state relays.
