Cygnus Operating Manual
6.3.4.2 Input/Relay Module Connections
The Input/Relay module, IPN 760-162-G1, is included as standard equipment with
the controller and is used to interface with other machinery of the vacuum system.
It can control components such as heaters, rotators or shutters through its 8 relays.
It can respond to external instructions through its 14 isolated input lines. Standard
equipment provides 8 relays and 14 input lines. Optionally, this can be expanded
to 24 relays, 28 TTL inputs, and 14 open collector type outputs with the addition of
2 optional I/O cards.
The module provides separate connectors for relay outputs and input lines. A
25-pin D-sub, male connector is used for the eight relays. A 15-pin D-sub, male
connector is used for the input lines. Mating connectors are provided in ship kits
IPN 779-610 and 760-024. Refer to
Figure 2-2 on page 2-3 for connector locations.
Relay connections are rated at 30 V(dc) or 30 V(ac) RMS or 42 V(peak) maximum;
2.5 A maximum.
Inputs are activated by pulling the specific Input terminal to ground (<0.8 V) through
a contact closure to common (GND) or with TTL/CMOS Logic having current sink
capability of 2 mA (1 low power TTL load).
WARNING - Risk Of Electric Shock
The relay, relay circuit, and associated pins in the I/O
connector(s) have a maximum voltage rating of 30 V(dc)
or 30 V(ac) RMS or 42 V(peak). The maximum current
rating per connector pin or relay contact is 2.5 Amps.
