DS7433 8 Input Module
1.0 General Information
The DS7433 is an 8 input Module for use with the DS7400(Xi) Series
Control/Communicator. It connects directly to the DS7400(Xi) and is
designed to expand it to 16 hard wired points. One DS7433 may be
used per DS7400(Xi) system.
• Current Draw: 65 mA S tandby. 80 mA with one point in alarm.
Add 15 mA per additional point in alarm.
• Maximum Loop Impedance: 60 ohms.
• End Of Line Resistor: 2.21 K ohm.
• 12 VDC Nominal Operating Voltage.
2.0 Installation
Warning: Failure to follow the mounting instructions in this
manual may result in damage to the DS7400(Xi)
Control Panel.
Caution: The DS7433 and DS7400(Xi) contain static sensitive
components and must be handled with care. Follow
anti-static procedures when handling the boards.
• Install the DS7433 board prior to installing the DS7400(Xi) board
into the control enclosure. If the DS7400(Xi) board is already
installed in the control panel enclosure, remove the 7400(Xi) board
this time.
• Place the DS7400(Xi) board on a flat surface with the component
side of the module facing up.
• Install the four plastic standoffs in the holes provided in the
DS7400(Xi) module. Avoid bending or flexing the DS7400(Xi) board
when inserting the standoffs. Be sure the standoff tabs are aligned
so that they do not touch any components on the module. Be sure
that the standoffs are firmly pressed into the board so that the
“ears” can expand out. See drawings.
• Install the DS7433 board onto the standoffs, noting that the
connector pins from the DS7400(Xi) are properly aligned to install
into the connector on the DS7433. Avoid bending or flexing the
boards while pressing them onto the standoffs.
