DESCRIPTION SNVT NAME SNVT TYPE

Command to open/close relay nvi Value SNVT_switch

Command status of relay nvo Value Fb SNVT_switch

Default state of relay on/o nci Default SNVT_switch

Communication timer nci Max Receive T SNVT_elapsed_tm

Status of Binary Input nvo Value SNVT_switch

Invert status of Binary Input nci Invert SNVT_lev_disc

Max time between updates nci Max Send T SNVT_elapsed_tm

Min time between updates nci Min Send T SNVT_elapsed_tm

The relay will go to the default state when the communication timer times out. Setting the timer value
to zero will cause the communication to never time out.

It is recommended to put a value in nci Max Send T to ensure the RIB re-synchronizes itself on the net­work after power loss. It is the responsibility of the user to ensure this value does not cause conicts in
network trac. (No value = No “heartbeat” updates / no re-sychronization; Low Value = Many updates
but may cause many trac collisions; High value = Few updates but many less collisions.)

Notes:

• Normally Open or Normally Closed selected by yellow

jumper wire.

• Order NEMA 4 housing by adding “-N4” to end of model

number. (RIBTWX2402SB-LN-N4)

• Order with grey lid by adding “-GY” to end of model

number. (RIBTWX2402SB-LN-GY)

• Order NEMA 4 housing with grey lid by adding “-N4-GY”

to end of model number. (RIBTWX2402SB-LN-N4-GY)

• When connecting 24 Vac to both the RIB(s) and a

half-wave device, damage to device can occur.
Option 1: Use separate transformers for each device.
Option 2: Add diode between devices, see Option 2
note below. ^^
