Description

Circuit boards contain devices that are susceptible to damage when exposed to

electrostatic charges. Damage caused by obvious mishandling of the board will

void the warranty. To avoid damage, observe the following precautions in the

order given.

Do not discharge static electricity onto the circuit board. Avoid tools or

procedures that would subject the circuit board to static damage. Some

possible causes include ungrounded soldering irons, nonconductive plastics,

and similar materials.

Personnel must be grounded with a suitable grounding strap (such as 3M

Velostat No. 2060) before handling or maintaining a printed circuit board.

Transport and store circuit boards in electrically conductive bags or foil.
Use extra caution during dry weather. Relative humidity less than 30% tends

to multiply the accumulation of static charges on any surface.

When performed properly, this module may be installed into or removed from

the rack while power is applied to the rack. Refer to the Rack Installation and

Maintenance Manual (part number 129766-01) for the proper procedure.

The 3500 system is available with two types of relay modules. The first type is

the 4 Channel Relay Module. The 4 Channel Relay Module is used for most

monitoring applications. It uses a single relay to drive the output for each

channel. See section 2.1 for additional information on the 4 Channel Relay

Module.

For applications that require high availability, the 3500 also supports a Triple

Modular Redundant (TMR) Relay Module. The TMR Relay Module uses three

independent relays to drive a single relay output. The TMR Relay Module works

in conjunction with a TMR Rack Interface Module and three monitor modules

configured as a TMR set to provide 2 out of 3 voting for inputs. See section 2.2

for additional information on the TMR Relay Module.

1) LEDs indicate the status of the relay channels.

2) Terminals for connecting relay contacts to external devices.

3) Switches that control how the relay contacts work.

4) 4 Channel Relay and I/O Modules

5) TMR Relay and I/O Modules

The 4 Channel Relay Module

The 4 Channel Relay Module is a full-height module that provides four relay

outputs. Any number of 4 Channel Relay Modules can be placed in any of the

slots to the right of the Rack Interface Module.

Each relay output is fully programmable using AND and OR voting. The Alarm

Drive Logic for each relay channel can use alarming inputs (alerts and dangers)

from any monitor channel in the rack. This Alarm Drive Logic is programmed

using the Rack Configuration Software.

The three common types of Alarm Drive Logic are bussed relays, individual

relays, and independent relays. Bussed relays use an Alarm Drive Logic that

ORs the Alerts or Dangers for all channels in the rack to drive a single relay.

Individual relays use Alarm Drive Logic that ORs the Alerts or Dangers for

channel pairs (channel 1 and channel 2 or channel 3 and channel 4) in a monitor

to drive a single relay. Independent relays use Alarm Drive Logic that cause

each alarm level (Alert and Danger) from a channel to drive a separate relay

channel. The following examples show the drive logic for these three types of

logic.

S = Monitor Slot A1 = Alert/Alarm 1

C = Channel A2 = Danger/Alarm 2
