Bistabile relay PB-1
Application : local or remote control, memorising the control signals
Advantages: contact status display , "CANCEL" button sets the contact in a fixed position
DC power supply backup relay PZ-1
The PZ-1 relay is used for the automatic supply voltage switching. In case of the basic voltage Up loss the relay switches the system to reserve voltage Urez. supply. When the basic supply voltage is back, the relay re-switches the system. The relay is used for switching the DC supply voltage.
Time relay PT-1
Application: The PT-1 time relay is a programmable delaying element, enabling the 4 mode operation : pick-up delay, drop-off delay, pick-up and recovery delay, cyclic operation
Advantages: all operation modes possible; LCD display; activation and operation signalling
Fast auxiliary relay PS-6
Very fast auxiliary relay used in the control and automated safety systems, with 6 independent NO contacts, working in 220 V DC circuits
Fast & Strong Auxiliary relays PHU-2/PHU-3/PHU-4
[technical data]
Auxiliary relays PD-2 / PP-4 / PP-6
Application: The PP-4, PP-6 i PD-2 relays are used in the control and signalisation circuits in the automated safety systems.
Advantages : two independent relays in one case, non-standard number ( 6) of the NO contacts operated by one coil
Switch-off circuits continuity control relay CW-3 A/B
Application: continuity control in one, two or three independent switch - off circuits; disruption signalling in automated systems; display and reproduction of three input signals; protection activation optical signalling; signalling failures and disruptions in electrical devices operation
Advantages: incident recording; memorising the initiation status after the power loss; configuration possible without power supply ( power from the USB)
Signalling relay - two signals - CS-2
Application: protection activation optical signalling; signalling the failures and disruptions in electrical devices operation
Advantages: display and reproduction of two input signals; continuity control in one or two independent switch-off circuits; incident recording possibility; memorising the activation status after the power loss; configuration possible without power supply (power supply from the USB )
Power supply circuits continuity check relay KO-3
Application: monitoring the supply circuits of the cable boxes and instrumentation boxes heaters; monitoring the current flow in three supply circuits; current control in the local switch redundancy automatics
Advantages: digital algorithms for the current measurement ( LEM converter), DC or AC measurement
