GMBHR168 Datasheet, PDF (12/70 Pages) List of Unclassifed Manufacturers – Mini BLOCK Housing 16 opto inputs, 8 Relay outputs

grifo^®
ITALIAN TECHNOLOGY
ANALOG INPUT
One analog input is available on signal MM PIN 33, it has been connected through a specific
circuitery that allows to acquire the analog signal directly or divided by 4.
OPTOCOUPLED DIGITAL INPUT LINES
The card features 16 NPN/PNP inputs connected to two quick release screw terminal connectors that
are directly acquired by 16 I/O lines of 40 pins socket through a galvanically isolated interface.
These lines are visualized by specific LEDs and have been selected to be able to take advantage
completely of eventual grifo^® Mini Module internal peripherals, in such case the inputs can generate
interrupts, be counted by hardware counters, etc.
Optocoupled inputs are supplied by a specific voltage called +Vopto generated on board by a specific
circuitery separated from +5 Vdc generation circuitery.
SERIAL COMMUNICATION
GMB HR168 features one AMP 4+4 connector (CN6) dedicated to serial communication.
By hardware it is possible to select the electric protocol, through a comfortable set of jumpers and
drivers to install.
In detail line can be not buffered (this means to connect signals MM PIN 9 and MM PIN 10 directly
to CN6) or buffered in current loop, RS 232, RS 422 or RS 485; in these last two cases also
abilitation and direction of line can be defined using signals MM PIN 17 or MM PIN 30.
In case a grifo^® Mini Module is installed, protocols TTL and RS 232 are immedatly available.
Please remark that by default the board is provided without drivers, so any configuration must be
specified in the order.
For further information about serial communication please refer to paragraph: “CONNECTIONS”
and “SERIAL COMMUNICATION SELECTION”.
I²C BUS LINES
GMB HR168 is provided with one connector (CN8) dedicated to I²C BUS, connected to two signals
of the 40 pins socket, MM PIN 12 and MM PIN 13, each provided with a 4.7 kΩ pull-up.
This kind of interface allows to connect devices featuring the same communication standard, to
easily improve the system performances.
Connector has been designed to allow both external and internal connections and satisfy any need
of the user.
A wide set of software examples explains the management of most common I²C BUS peripherals like
A/D and D/A converters, display drivers, memories, temperature sensors, etc.
GMB HR168 can be ordered with a Real Time Clock provided with 256 bytes of SRAM already
installed (option .RTC), in such case the slave address A0H is already taken by this peripheral,
eventual third part hardware cannot use it, in addition a grifo^® Mini Module provided with its own
Real Time Clock cannot be installed for the same reason.
