4.2 Rivo™ Flex Mod Output Modules (optional)
Rivo™ Flex Mod 2 Rel-2DO
Article number W3T557914
Description Relay module for activation of dosing outputs and alarms
Relay outputs
(only if
Rivo™ Flex Mod 2 Rel-2DO
is used)
Version • 2x changeover contact with integrated fuse (5 A,
not replaceable)
Nominal breaking capacity • 3A 250V AC, 1250VA max. (resistive load)
• 1A 250V AC, 250VA max. (cos ɸ = 0.4)
• 3A 30V DC, 150W max. (resistive load)
Max. switching voltage • 250V AC / 30V DC
Max. switching current •
UL/CSA rating • 3A, 125/250V AC (general use)
• 3A 30V DC (resistive)
Digital outputs
(only if Rivo™ Flex Mod
2Rel-2DO is used)
• Optocoupler output for connection of enabling inputs to dosing systems, dosing pumps,
electrolysis systems
• Max. ext. power supply 24 V DC
• max. current 20 mA
NOTE
When connecting inductive or capacitive loads (e.g. pump with integrated switching power supply), an additional power
relay with suitable specification must be provided. Each relay output has an integrated 5 A fuse as overcurrent protec-
tion.
Typical use of the relay: Enabling contact for external alarm or activation of the dosing devices or dosing pumps.
