Extended I/O of the DMC-17x8/1700/1800 Controller

Opto-Isolated Outputs ICM-1900 / ICM-2900 (-Opto option)

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: ICM-1900-OPTO (standard) and ICM-1900-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.

64 Extended I/O of the DMC-17x8/1700/1800 Controller

The DMC-17x8/1700/1800 controller offers 64 extended I/O points, which can be interfaced to Grayhill and OPTO- 22 I/O mounting racks. These I/O points can be configured as inputs or outputs in 8 bit increments through software. The I/O points are accessed through two 50-pin IDC connectors, each with 32 I/O points.

The 64 extended I/O points of the DMC-17x8 (and 1750-1780 & 1810-1880 w/DB-14064) series controller can be configured in blocks of 8. The extended I/O is denoted as blocks 2-9 or bits 17-80.

The command, CO, is used to configure the extended I/O as inputs or outputs. The CO command has one field:
