5. Check the actual output value at the modules terminals. If this
does not equal 4 mA, use the "Trim" option in the "Calibrate"sub-
menu to change the actual output. Trim the module until the mA
meter indicates exactly 4 mA, or in case of a voltage meter with
shunt resistor, the meter indicates exactly 1 V. (When calibrating
for 20 mA using a voltage meter and shunt resistor, the correct
voltage should be 5 V.)
6. Issue the 4 mA Calibration command to indicate that the output is
calibrated and to store the calibration parameters in the module's
EEPROM.
7. Execute an Analog Data Out command with an output value of
20 mA. The module's output will be approximately 20 mA.
8. Execute the Trim Calibration command as often as necessary until
the output current is equal to exactly 20 mA.
9. Execute the 20 mA Calibration command to indicate that the present
output is exactly 20 mA. The analog output module will store its
calibration parameters in the unit's EEPROM.
4.5 Digital Input/Output Modules
ADAM-5050 16-channel universal digital I/O module
The ADAM-5050 features sixteen digital input/output channels. Each
channel can be independently configured to be an input or an output
channel by the setting of its DIP switch. The digital outputs are open-
collector transistor switches that can be controlled from the ADAM-
5510. The switches can also be used to control solid-state relays,
which in turn can control heaters, pumps and power equipment. The
ADAM-5510 can use the module’s digital inputs to determine the state
of limit or safety switches, or to receive remote digital signals.
Warning!
A channel may be destroyed if it is subjected to an
input signal while it is configured to be an output
channel.
