Dual Ionization Gauge Connector Box
Option O100IG

The standard IGC100 controller can connect to, and display pressures from, only one ionization gauge.
The Dual Ionization Gauge Connector Box (SRS Model # O100IG) is an optional component that, when
attached to an IGC100, makes it possible to simultaneously connect two ionization gauges to the IGC100.
An IGC100 properly fitted with the O100IG optional box can switch operation between two independent
ionization gauges (i.e. sequential operation) from the front panel, and measure pressure at a first or second
location (IG1 or IG2) at a small fraction of the cost of a second instrument.

The O100IG option is easily installed in the field making it easy to extend the capabilities of the IGC100
controller as needed.

What does the Kit include?
The O100IG Option Kit includes all the components required to add a second ionization
gauge connection port to your IGC100 controller. The basic package includes...

1. Dual Gauge Connector Box.
2. Connection Cable ( connects O100IG box to IGC100 controller)
3. Mounting pins ( for side mounting)
4. Fastening screw (for side mounting).
5. Instructions sheet.


Installation
IMPORTANT
For the most compact design and safest operation, SRS recommends you mount the
O100IG box on the left side of the IGC100 controller as shown below in Fig. L-1.
However, side mounting is not a requisite for the proper operation of the O100IG option
(i.e. steps 1
