Galil DMC-3425 user manual Opto-Isolation Option for ICM-1460, Opto-isolated inputs

Page 185

4The screw terminals for ACMDX and ACMDY can provide access to 2 sets of signals, depending on the placement of the 2 jumpers on JP3.

5If the Opto-isolated input option is used, the output compare is NOT brought out to the ICM-1460. If the output compare is to be used in conjunction with the opto-isolation, pin 23 of the Cable 37-Pin D must be brought out externally. There are also options for using either terminal 1 or 2 as the Common connection. Contact Galil for more information.

Opto-Isolation Option for ICM-1460

The ICM-1460 module from Galil has an option for opto-isolated inputs and outputs. This option is specified as ICM-1460-OPTO*. With this option, the user is able to use voltages up to 24V on the inputs and outputs of the controller.

The common point for the opto-isolation may be chosen from any of the following pins: pin 1 (labeled as +12V), pin 2 (labeled as –12V) or pin 13 (labeled as CMP/ICOM). When pin 1 is used as input/output common, the +12V output be comes inaccessible, when pin 2 is used, the –12V becomes inaccessible, and when pin 13 is used, the output compare function is not available. This common point must be specified at the time of ordering.

The ICM-1460 may also be configured such that the input/output common is jumpered to the internal Vcc (+5V). By doing this, no screw connection is needed so no signals are lost.

A final option for the opto-isolation is for separate input/output commons. This allows the user to have different voltage levels for the inputs and outputs. However, this requires the use of both pin 1 and pin 2 on the screw connection, making both +12V and –12V inaccessible on the screw terminals.

Opto-isolated inputs:

The signal "IN[x]" below is one of the isolated digital inputs where x stands for the digital input terminals.

By connecting the OPTO-COMMON to the + side of an isolated power supply, the inputs will be activated by sinking current. By connecting the OPTO-COMMON to the GND side of the power supply, the inputs will be activated by sourcing current.

The opto-isolation circuit requires 1ma drive current with approximately 400 usec response time. The voltage should not exceed 24V without placing additional resistance to limit the current to 11 mA.
