Electrical Specifications

 

 

Drive Capacity - 87130A

248 relays, when mated with seven external 84940A daisy chained driver cards.

 

Each 84940A can drive up to 31 relays. The equivalent of one 84940A

 

driver card is installed within the 87130A.

 

 

Voltage

+ 24 + 3.0 / − 1.5 Vdc

 

 

Current Pulses

1600 mA maximum per four relay group

 

400 mA per relay (typically 500 mA maximum)

 

Pulse width is adjustable for 5 ms to 1275 ms ± 5 ms, in 5 ms steps.

 

 

Load Inductance1

Typically < 500 mH

 

 

Load Capacitance

Typically < 0.01 F

 

 

Switching Speed

Sensing delay is adjustable, per relay, from 5 to 1275 ms ± 5 ms. Pulse width is also

 

adjustable, per relay, from 5 to 1275 ± 5 ms. Power Supply RecoveryTime is adjustable

 

from 0 to 200 msec

 

Refer to Chapter 6, “Troubleshooting.” The final switching speed is a function of

 

pulse widths, sensing delays, the sequence of relays driven, the state of the chosen

 

channels, and the Power Supply Recovery Time.

 

 

Remote Programming

All functions are GPIB programmable except the line switch and bus address.

 

All functions are programmable to conform with IEEE 488.2-1987 Standard Commands

 

for Programmable Instruments (SCPI).

 

The 87130A can output over the interface almost all settings, error/malfunction codes

 

and operational status codes.

Interface to Controller

GPIB

 

 

Interface to External Driver Cards

36-pin SCSI II type

 

 

Interface to Relays

68-pin SCSI II type

 

 

Hardware Limits

Each open collector driver IC can drive only one channel (a maximum of four switches) at

 

a time to avoid exceeding package dissipation limits.
