IC6 Operating Manual
2.3.2.4 I/O Expansion Options
One I/O Relay module is included as standard equipment with the IC6 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 another Relay I/O
module 781-502-G1 and a TTL Relay module 781-503-G1 having 8 relays and 14
TTL open collector outputs.
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 781-502-G1 and 781-503-G1. Refer to
Figure 3-2 on page 3-3 for connector
locations and Table 2-3 on page 2-10 for connector pin assignments. 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.
