Product Name: PMAC2A PC/104 4 Axis Stand-alone or PC104 Bus Controller

Product Description

Designed for OEMs or end users, the PMAC2A PC/104 delivers a powerful 4- or 8-axis embedded control system for a cost-effective and compact, yet flexible and reliable solution. 

The PMAC2A PC/104 can be applied directly to both analog servos or pulse-and-direction stepper drives. With optional piggyback accessory boards, it can support high speed communications with USB2.0 or Ethernet, Digital I/O with Opto-22 interface, additional axis expansion for 5-8 Axis of control and high-performance direct-PWM, pure digital control.
