The Tektronix 015-0274-00 is an AC switching unit plug-in for the TM500 system.

A two-wide TM500 module, it is the output signal controller for the TEKTRONIX Model WP1100AC Ultrasonic Velocity Test System used for foundry quality control.

The Physical Measurements Handbook says,

It has many uses as an output device for TEK 31 Calculator-Based Systems used to control ac line powered equipment in cyclic testing, life testing, quality control testing, and any activity where some action must be taken as the result of the data obtained. The AC Switching Unit is a device that can be used to randomly switch on (close) and switch off (open) up to 10 discrete, 115 V AC circuits under the remote control of a TEK 31 Calculator. Components included in the unit are 10 solid state relay switches, TTL logic drivers, and the input logic decoding circuitry to operate those components from the calculator data and control bus. Each of these normally open switches the TM 500 family a natural for the fabrication of test makes contact at zero V AC and break contact at zero to minimize the switching transients associated with most relays.

Board construction includes two adjacent calculator I/O connectors that are accessed through the unit front panel by the TEK 31 I/O cable (PN 012-0498-01).

The ac switches are connected through a front panel 28 pin connector and mating 15 foot cable (PN 012- 0706-00). The TTL signals are available at a DB25S front panel connector.

Key Specifications

Output Characteristics (each solid state relay switch)

  • Current (rms): 0.05 A min to 2.0 A max
  • Voltage (rms): 12 V min to 180 V max
  • Frequency range: 50 Hz min to 70 Hz max
  • Contact voltage drop: 1.5 V max
  • Turn on time (60 Hz): 16 ms
  • Turn off time (60 Hz): 16 ms
  • Voltage across load at turn on (115 V ac): 0 ± 6V
  • Off state leakage (— 30°C to 100°C): 10 mA (rms)
  • Voltage switch contact separation (turn off): 0.0 ± 12.0 V AC
  • Turn on voltage: 3.0 V min to 3.8 V max
  • Turn off voltage: 0.8 V min to 1.0 V max

TTL Contacts

  • Loading: 1.6 mA min/max

Load voltages less than 90 VRMS will slightly degrade the zero voltage switching performance.
