The UMI-7774/72 includes the following features:
• D-SUB connectivity, which provides easy and durable connectivity to third-party devices.
• 5 to 30 V limits and home switch/sensor compatibility.
• Global Stop inputs for global shutdown of all axes.
• Optical isolation on inhibit signals, Global Stop inputs, triggers, limits, home, and digital I/O. This
feature enables 24 VDC signaling capability. Also, the isolation can help break ground loops in the
system and reduce the effects of noise and voltage transients.
• Global and per-axis status LEDs.
• Access to eight digital inputs and eight digital outputs.
• Panel, DIN rail, or rack mountable.
