J3 Interlock
This is intended to connect to a test area enclosure switch that opens when
the door is opened. If not used, a jumper plug (p/n 049-635-901) must be
installed. If you are building a cable, maximum length is 30.48 m (100 ft)
with 24 gauge wire. Switch should be wired normally closed, such that when
the switch opens, an interlock is generated.
J4 Encoder
This connector is intended for an encoder based extensometer. Specifics for
this connector: are
• Power: +5 V +/- 0.25 V at 100 mA max
• Signals: Quadrature A and B with index I
• Logic: Differential receivers (can connect single ended)
• Maximum Rate: 100,000 lines/sec = 400,000 counts/sec
Pin assignment is as follows:
