II. Metal Box-Type DMC-21x3-BOX and Associated Accessories

1. Metal Box-Type DMC-21x3-BOX

The DMC-21X3-BOX is a new product designed by Baolun Company to facilitate connection for the wide range of users who employ the DMC-21x3 series digital motion controllers from the U.S.-based company GALIL. Users connect this device to servo or stepper drivers via four 15-pin D-type connectors to control up to four axes. One 37-pin connector is used to interface with external input and output signals, including eight input points, eight output points, positive and negative limit switches for all four axes, home-position input signals, as well as controller reset and emergency-stop input signals. Additionally, a 25-pin D-type connector provides auxiliary encoder functionality for handwheel operation and a second encoder function. A DC 24V power input terminal is also included. Furthermore, all TTL-level input and output signals undergo optoelectronic isolation circuitry, significantly enhancing the system’s resistance to interference. This allows users to easily interface external signals with the DMC digital motion controller.

 

The image of the DMC-2143-BOX four-axis standalone box-type controller is shown below:

 

 

The external dimensions (unit: mm) of DMC-2143-BOX are as follows:

 

 

2. PICM-20105 Interconnection Module

The PICM-20105 interconnection module is a new product designed to facilitate connectivity for the broad user base that employs digital motion controllers from the U.S.-based GALIL company, specifically the DMC-21x3 series. It connects to the DMC-21x3 controller via a 96-pin DIN connector. Users connect to servo or stepper drives through four 15-pin D-type connectors to control up to four axes. One 37-pin D-type connector is used to interface with external input and output signals, including eight input points, eight output points, positive and negative limit switches for all four axes, zero-return input signals, as well as controller reset and emergency stop input signals. Additionally, one 25-pin D-type connector provides auxiliary encoder functionality for handwheels and a second encoder function. A DC 24V power input terminal is also included. All TTL-level input and output signals undergo optoelectronic isolation circuitry, significantly enhancing the system’s resistance to interference. Users can easily establish interfaces between external signals and the DMC digital motion controller. Each PICM-20105 unit provides four coordinate-axis signal interfaces. When users employ a DMC digital motion controller with more than eight axes, they will need to use two PICM-20105 units.

3. DB-28040 I/O Expansion Board

The DB-28040 connects directly to the DMC-21x3 via a 50-pin IDC connector, providing 40 extended I/O channels and 8 analog input channels. The standard voltage for the extended I/O channels is 3.3V; if you require 5V I/O channels, please order the DB-28040-5V model. On the DB-28040, the 40 I/O channels are configured on a 50-pin IDC socket, while the 8 analog input channels are connected via a 16-pin IDC socket. With adjustments made through patch software, the DB-28040 can also receive feedback values from SSI encoders.

4. AMP-204x0 2-axis and 4-axis 200W servo drives

The AMP-20440 can drive up to four brushed servo motors, each with a maximum output power of 200W. Each amplifier offers a driving capability of up to 20–60V and 3.3A, and does not require an external heat sink. The AMP-20440 connects to each motor via a 2-pin Molex connector, while a single 15-pin high-density D-sub connector is used to link the encoder signals as well as limit and home-position signals for each axis. Extended I/O signals are defined on a separate 44-pin high-density D-sub connector. A DC power supply with a voltage range of 20–60V can be connected via a single 4-pin Molex connector. If you only need to control two-axis motors, you can opt for the AMP-20420.

 

5. AMP-205x0 500W servo drives for 2-axis and 4-axis applications

The AMP-20540 can drive up to four brushed or brushless servo motors. Each amplifier offers a driving capability of up to 18–60V and 7A (continuous, with a maximum of 10A). Users can programmably set the amplifier’s gain to 0.4Amp/Volt, 0.7Amp/Volt, or 1Amp/Volt. Meanwhile, the amplifier provides protection against conditions such as overvoltage, undervoltage, overcurrent, short circuits, and overheating. The amplifier’s status can be read back via the DMC-21x3, and the BS command allows for easy testing of Hall sensors. If you only need to control two-axis motors, you can opt for the AMP-20520.
