2.3 Connecting the Model 1460 I/O Expansion Module
Like the 1350 Breakout Module and the Model 1450 I/O Expansion Module, the optional Model
1460 I/O Expansion Module (P/N 800-5815), shown in Figure 2-6, provides convenient access to
an In-Sight 3400 sensor's power, serial communications and discrete I/O lines. In addition to the
two discrete outputs, acquisition trigger and serial transmit/receive that are standard on In-Sight
3400 sensors, the Model 1460 I/O Expansion module provides the following:
8 discrete outputs
8 discrete inputs
RS-232 hardware handshaking
Light Control
Plug-in connections for I/O opto-isolator modules
To Connect the Model 1460 I/O Expansion Module to the In-Sight
Sensor:
1. Verify the 24VDC power supply being used is switched off.
2. Connect the power and ground wires from remote I/O devices to terminals on the
1460 I/O Expansion Module (Figure 2-6).
Figure 2-6: Connecting I/O Wires
a.
Use a Flat-head screwdriver to loosen the screw terminals.
b.
Insert the wire leads from remote I/O devices into the appropriate positions on the
terminal block.
NOTE The 1460 I/O Expansion Module outputs labeled HSOUT 0 and HSOUT 1 correspond to
the In-Sight 3400 sensor's built-in outputs. These signals pass through the micro-
controller on the 1460 I/O Expansion Module without processing. In contrast, the
general-purpose outputs labeled OUT 0 through OUT 7 are lower speed because the
micro-controller processes these signals before they are transmitted to remote devices.
