Tracker 340 Expansion Module
1. Introduction
The Tracker 340 expansion module is connected to a Tracker 300 series
instrument via the expansion port. The Tracker 340 is powered by and
configured via the Tracker 300.
2. Connections
The diagram below shows the terminal connection arrangement.
Relay Connections
Logic Connections
3. Connecting the Status Inputs
There are two status (logic) inputs provided on the Tracker 340 expansion
module. The inputs can be used with either voltage free contacts, such as
relay contacts, switches, open collector transitor outputs, or voltage driven.
The inputs are active low, i.e. apply a short circuit between the status input
and status common. The following diagrams illustrate typical applications.

TTL Outputs
Voltage Driven
Note: 0V is active
4. Indicators
There are six LEDs on the front panel of the instrument, two green (input)
and four red (output).
Green LED Status Inputs 1 & 2– lit when the respective status input is
active.
Red LED 1, 2, 3 and 4
– programmable LEDs.
