Specifications

Bandpass
With 50 ohm terminations, the bandpass is from DC to 30 MHz.
Isolation
With 50 ohm terminations, the isolation between channels is:
10 kHz - 90 dB 100 kHz - 70 dB 1 MHz - 50 dB
Relays can be supplied with Type S, Type M or Type LT
contacts. Type M versions must be operated in a vertical
position.
PC-B/2(8x1) SWITCH MODULE
The PC-B/2 (8x1) Switch Module is a general purpose mod-
ule which can be used in either Matrix or Multiplexer appli-
cations. It has 16 two pole relays configured as two sepa-
rate 8x1 two wire Multiplexers as shown in Fig. 3 which
can be jumpered as one 16x1 two wire Multiplexer.
By using one Form C relay to submultiplex the 16x1 mux, the
module can be used as a 30x1 single pole Mux as shown in
Fig. 4.
Type S - Standard relays for Instrumentation Level Signals.
Type M - Mercury relays for high current switching.
Type MG - Mercury Amalgam Non-Position Sensitive Relays.
Type LT - Low Thermal relays with less than 1 microvolt offset.
Switches are guaranteed for 100,000 operations if used within
the following specifications:
There are two basic types of Modules: the PC-B/24 Relay Driver Module, and the IF-PC TTL Compatible Input/Output
Module. Both Modules are half slot size and have 37 pin female D type connectors. Mates are available for ribbon cable
or crimp pin type wiring.

PC-B DRIVER MODULES
PC-B/24 DRIVER MODULE
This Module has 24 separate relay drivers which can be
used to select and control CYTEC Switch Modules or any
other types of relays.
The 24 Relay drivers are in three groups of eight high voltage,
high current Darlingtons with open collector outputs and inte-
gral suppression diodes. Any number of these drivers can
be selected at any time and the Status of the drivers se-
lected can be verified by the computer.
Each driver can operate on different voltages up to a maximum
of 50 volts and current up to 500 mas, with a maximum of 1500
mas within any group of 8 drivers.
This is a half slot size module and has TTL compatible out-
puts and inputs suitable for selecting up to 8,192 relays
and checking Status of the relays in any of the CYTEC Se-
ries of Switch Matrices.
The relays can be Latched or Unlatched in the Matrix or Multi-
plex Mode, or an entire matrix can be cleared. Status of all
relays can be verified and displayed on the Computer Monitor.
Power requirements are dependent on the system size and can
be supplied with the Matrix chassis.
