POWER SUPPLY SECTION
GMB HR168 is provided with an efficent switching power supply section, that provides supply +5
Vdc voltage needed by logic and output circuits, in any condition of input load and voltage.
A second section is present and generates the rectified voltage +Vopto, allowing to use the
optocoupled inputs simply closing its contact with the respective common terminal.
This latter section requires a separated power source.
The board features components and circuits designed to reduce consumptions and to reduce noise
sensibility.
Remarkable is protection circuit based on TransZorb™ that avoids damages due to incorrect
voltages.
To supply optocouplers of galvanically isolated sections a voltage between 12÷24 Vdc is needed.
For further information please refer to chapter “ELECTRIC FEATURES” and paragraph “SUPPLY
VOLTAGES”.
TELECONTROL FIRMWARE
The Mini Module installed on GMB HR168 can be provided with a telecontrol firmware; such
firmwares allow to manage all the board resources through a set of commands to send to the serial
line.
Taking advantage of these firmwares make possible to use well developed commands that solve
fundamental problems of automation like impulse count, wave from generation, debounced input
acquisition, Real Time Clock managentent, etc.
For grifo^® Mini Module, Master Slave communication mode is supported; this allows to remote
single modules also at great distance, to build a telecontrol network driven by a unique master unit
(PC, PLC, GPC^®, etc.).
By now, some standard protocols like ALB x84 (ABACO^® Link BUS) and MODBUS are available,
anyway new protocols can be developed on specific request of the customer.
Please contact grifo^® for further information.
