- ZIEHL current-relays STW1000V2 monitor standardsignals from measuring transducers if a limit is exceeded. For monitoring of more than 1 signal, multiple relays can be connected in series (current) or in parallel (voltage).
- Monitoring of different values in combination with measuring transducers, e.g. in machines and controls.
+ Measuring inputs 0-20 mA / 0-10 V, switchable to 4-20 mA / 2-10 V
+ Limit adjustable 0-100 %
+ Hysteresis adjustable 5-30 %
+ Start-up delay adjustable 0,1 ... 10 s
+ Switching delay adjustable 0,1 ... 10 s
+ Output-relay 1 changeovercontact (co)
+ Operating- or closed-circuitmode for relay selectable with bridge
+ LEDs for display state of operation
+ Universal supply-voltage AC/DC 24-240 V
+ Housing for mounting in switchgear cabinets or fuseboxes, 35 mm wide
