The PC-B Series Modules plug into PC/AT/XT Compatible ISA Bus slots. The PCI Modules plug into PCI
slots. Both are available as either Switch Modules or Driver Modules. The modules can be controlled
either by direct hardware port access or by installable Device Drivers. PCI Moduldes come with Plug and
Play device drivers. Software support is available for the most common program languages.
The modules also have a special Status feedback feature which enables the computer to confirm that the
correct selections have been made by checking the relay drive. This can be used to self test the modules
or as a diagnostic tool.
PC-B/PCI SERIES MODULES
Each Module has 16 high reliability reed relays with operate times less than 2 msec and guaranteed for
100 million operations. Relay options offered are Standard Dry Reed, Mercury Reeds for high current and
Low Offset Reeds for microvolt signal levels.
The Signal Input connector in each module is a 37 pin male D type connector and mates are available for Ribbon
Cable wiring or for individual Crimp Pin wiring. External screw terminal blocks are optionally available.
All modules have Status feedback and LEDs associated with each relay for visual indication of the relays
energized.
Power Requirement +5 volt < 0.2 Amp +12 volt < 20 mas per relay energized.
PC-B SERIES SWITCH MODULES
This module has 16 two pole relays as shown in Fig. 1 with
selection of any one of 16 inputs to one output and Break
before Make Switching. Only one relay may be selected at
any time.
This module has 16 single pole discrete Form A relays as
shown in Fig. 2. Any number of the relays may be latched
simultaneously. Relays may be wired externally in any re-
quired configuration.

PC-B/K16 SWITCH MODULE
Bandpass -- With 50 ohm terminations, the bandpass is flat to
within 1 dB from DC to 10 MHz and is within 3 dB up to 70 MHz.
Isolation between Inputs to Outputs across unused channels
with 50 ohm terminations is as follows:
10 kHz - 90 dB 100 kHz - 70 dB 1 MHz - 50 dB
Relays can be supplied with Type S, Type M, Type MG, or
Type LT contacts. Type M versions must be operated in a
vertical position.
