EA KIT320-8
INPUTS AND OUTPUTS
All EA KIT320 operating units are supplied with 8 digital
inputs and 8 outputs (5V CMOS level, non-isolated).
8 outputs
Each line can be controlled by means of the „ESC Y W“
command. The maximum current per line is 6mA. It is
therefore possible to connect an LED (low current)
directly to an output. Higher currents can be amplified
by means of external transistors.
8 inputs
The inputs can be queried and evaluated („ESC Y R“)
directly via the serial interface. It is also possible to call
a bit/port macro automatically in the event of changes
at the inputs. Automatic port querying can be
deactivated by means of the „ESC Y A 0“ command.
Port macros: Up to 256 port macros can be addressed by means of the binary
combination of 8 inputs.
Bit macros each only affect one input. Bit macro 1..8 is called at one of inputs
1...8 in the event of a change to HIGH level. Bit macros 9..16 are called in the
event of a change to LOW level.
At each change of the input port, the bit macros are executed first, followed by
the port macro. If there is no macro defined, the new port status is sent via
RS232/RS422. Each of the macros can change the contents of the screen or
switch outputs. This allows a wide range of control tasks to be carried out. To
create the macros, you need a PC and the floppy disk EA DISK320.
Note: The logic circuitry is designed for slow operations; in other words, more
than 3 changes per second cannot be easily executed. If an input is open, this
is evaluated as high (internal 100 kOhm pullup).
INPUTS AND OUTPUTS VIA OPTOCOUPLERS (EA OPT-OPTO16)
The inputs and outputs can be equipped optionally with optocouplers
(EA OPT-OPTO16). The inputs and outputs are then isolated from the rest of
the electronic components as well as each other. The connection is made via
16 different screw-type terminals.
Voltages of 5..35V can be applied directly at all
8 inputs. Voltages of over 4V are identified as high (H)
level; voltages of under 2V are identified as low (L)
level. Voltages between 2 and 4V are undefined.
The collector and emitter of a transistor are each
implemented as outputs on the screw-on terminals.
Each output can switch a maximum of 10mA.
Note: The negative pole of each screw-on terminal
can be interconnected by closing solder straps
LBI1..8 or LBO1..8. In addition, these solder straps
can be connected to system GND (solder 0Ω bridge RGND).
Note: The optocouplers invert the input logic (all inputs open: port macro n°255). It is advisable here
(in the power-on macro, for example) to use the „ESC Y I 1“ command to evaluate the inputs inversely
(i.e. all inputs open: port macro n°0).
