Introduction:

The Phoenix Contact Optima MD/100 module provides a convenient field termination for motion control signals that are interfaced to a Galil motion control card, such as the DMC 1700 and DMC 1800 series. Galil controller signals are broken out to individual screw terminals, with connections for stepper motors or servo motors and encoders. Terminals are also provided for limit switches, discrete (digital) I/O and analog inputs to the Galil card.

Each module accommodates up to 4 motion axes. A second module and a cable adapter kit are required for systems with 5 to 8 axes of motion.

When to use the Optima MD/100

Use the...	When...
Optima MD/100	an enclosure is available. (e.g. controls cabinet or other housing). compact footprint is required. Optima requires 8.5 in X 4 in (22 cm X 11 cm) DIN Rail mounting is required. (MD/100 also includes hardware for mounting to a panel) you require field configurable amp-enable logic
ICM 1900	a stand-alone, enclosed module is required. a large mounting area is available. ICM 1900 requires 13.5 in X 7 in (35 cm X 18 cm)
ICM 2900	you need a compact through-hole panel mounted module, you require piggy-back mounting to a stand-alone drive you need to plug and unplug motors from the interconnect module. A small footprint is required. ICM 2900 requires 12.25 in. X 2.5 in (32 cm X 7 cm)

Installation:

The Optima MD/100 has tabs for snap-on mounting to standard 35 mm DIN-Rail. It can also be screwed down to a panel by removing the DIN rail clips and installing mounting ears. (The alternative mounting hardware is included.)

The module may be mounted either vertically or horizontally.

Appropriate mechanical support and strain relief must be provided both for the Galil interconnect cable, and for the field wiring.

The terminal names on the Optima differ slightly from those on the Galil ICM1900 and ICM2900. See the table below for a functional description of each of the Optima MD/100 terminal names.

Amp Enable Configuration:

The Optima MD/100 module has field configurable options for the amplifier enable control logic. All of the necessary hardware ships with the unit.

Amp Enable requires...	Use...
Active High	IC 7407 in socket U2 (standard configuration)
Active Low	IC 7406 in socket U2 (use alternate chip - provided)
5 Volt pull-up	resistor pack RP1 with pin 1 at the 5V mark
12 Volt pull-up	resistor pack RP1 with pin 1 at the 12V mark
No Pull-up	remove resistor pack from the RP1 socket (Amp Enable output signal is an open collector)
other voltages	remove resistor pack from the RP1 socket The open collector Amp Enable output signal may be pulled up externally to a maximum rail voltage of +24 V.

Note:

IC Chips are static sensitive devices! Be certain to use appropriate grounding and ESD prevention procedures when handling these chips.
Standard configuration for ICM 1900/2900 is Active High. Galil does not provide the optional 7406 (Active Low) chip with the unit.

Additional Information:

See the Galil website for additional information and related support documentation.
