Relay outputs
(Backboard 4)
Version • 2x changeover contact with integrated fuse, replaceable
• Type TR5 3,15 A T
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
UL/CSA rating • 3A, 125/250V AC (general use)
• 3A 30V DC (resistive)
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 3.15 A fuse as overcurrent pro-
tection.
Typical use of the relay: Enabling contact for external alarm or activation of the dosing devices or dosing pumps. If the
relay is used to switch inductive loads with direct voltage, the load must be equipped with a suppressor circuit against
overvoltage (free-wheeling diode etc.).
