Revision B 20
Note
: Gain settings for each jumper position are as follows: no jumper = 1, LOW = 7, MED = 21, HI = 41.
Multiple jumpers have an additive affect upon gain, so the LOW and MED jumpers together provide a
gain of 28.
Initial setup is now complete, and normally only requires repeating if a sensor is replaced.
Final calibration of this channel may now be performed using the ViewSmart 1600+’s electronic Cal Mode
feature described in Chapter 5.
3.4.3 Isolated RS-485 Modbus® Option
The Isolated RS-485 Modbus® Option plugs in to the I/O Expansion Connector (J5) on the Main I/O board.
Adding this option provides two additional communication ports, which are wired in a similar fashion to
the Standard Communication Ports as described in Chapter 3.3.3. Setup for these Comm Ports (Comm
Port 3 and 4) is identical to the Standard Communication Ports, which can be found in Chapter 4.2.1.
3.4.4 Relay Options
The Programmable and Discrete relay options add 8 relays per board. The Auxiliary Relay Option adds 5
relays to the Main I/O, which mimic the common relays. All relays are 5 Amp Single Pole Double Throw
(SPDT) relays, and are rated at 5 Amps for 28VDC and 250~VAC Resistive Loads.
3.4.4.1 Auxiliary Relay Option
The Auxiliary Relay Option plugs in to the Relay Expansion Connector (J3) on the Main I/O board. Adding
this option provides five additional standard relays, which are wired in the same fashion as the Common
Relays (described in Chapter 3.3.1). Setup for these relays is completed when setting up the Common
Relays as described in Chapter 4.2.4.
3.4.4.2 Programmable Relay Option
The ViewSmart 1600+ supports up to two Programmable Relay Option Boards for a total of 16 fully
programmable relays.
IMPORTANT
: Appropriate diode (DC loads) or MOV (AC loads) snubber devices must be
installed with inductive loads to prevent RFI noise spikes. Relay wiring should be kept separate
from low level signal wiring.
Terminals for the Programmable Relays are found on TB1 and TB2.
Relay terminals are labeled NO for the Normally Open terminal, C for the Closed Terminal and NC for the
Normally Closed Terminal. The NO and NC nomenclature comes from the normal state of the relay (de-
energized state). The Fault Relay (or relays when placed in Failsafe Mode) is normally in the energized
state, and becomes de-energized when the Fault (alarm) condition is reached.
