Controller Connections
Installation
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:
