Opto-Isolated Outputs for ICM-2900/ICM-1900/AMP-19520/40
The ICM/AMP 1900 and ICM-2900 modules from Galil have an option for opto-isolated outputs.
Standard Opto-Isolation and High Current Opto-isolation:
The Opto-isolation option on the ICM-1900 has 2 forms: -opto (standard) and -optohc (high current). The standard
version provides outputs with 4ma drive current / output with approximately 2 usec response time. The high
current version provides 25ma drive current / output with approximately 400 usec response time.
The ISO OUT POWER (OUT POWER ON ICM-2900) and ISO POWER GND (OUT GND ON ICM-2900) signals should be
connected to an isolated power supply. This power supply should be used only to power the outputs in order to
obtain isolation from the controller. The signal "OUT[x]" is one of the isolated digital outputs where X stands for the
digital output terminals.
The default configuration is for active high outputs. If active low outputs are desired, reverse RP3 in it's socket. This
will tie RP3 to GND instead of VCC, inverting the sense of the outputs.
NOTE: If power is applied to the outputs with an isolated power supply but power is not applied to the controller,
the outputs will float high (unable to sink current). This may present a problem when using active high logic and
care should be taken. Using active low logic should avoid any problems associated with the outputs floating high.
