Frequency 47 to 63 Hz
Fuse
Time- or Operator-
Controllable Switch
Closures
Four controllable switch closures to ground as follows:
• TTL-compatible terminals pulled up with 10-K ohm resistors to 5 V.
May be pulled up to 12 V.
• Maximum allowable current = 1.0 A
• Maximum allowable voltage = 12 V. Outputs may be controlled
directly from keyboard or from events program.
• Two modes available from keyboard and Program Events screen:
ON = switch closed to ground
OFF = switch open, +5 V to ground
• Additional mode available from Program Events screen:
Pulse = single contact closure to ground for 600 msec
