Материал из Wiren Board
Parameter Value
"Power Supply"
Supply voltage 9 — 24 V DC
Power consumption
  • Idle mode (all relays switched off) — 0.10 W
  • All relays-0.5 W
  • Peak value (all relays are switched on simultaneously) — up to 2 W for 20 MS.
Terminals and wire section
Recommended wire cross-section with NSUI, mm2 0,75 — 1 (for plates screwless terminals), 1.5 a for relay outputs
Length of the standard sleeve NSVE, mm 8 (10 for adjusting screwless terminal blocks)
Torque of screws, N∙m 0,2 (for screw terminals), 0,4 — for relay outputs
Outputs
Number of outputs 2
Output type Mechanical relay contacts
Contact configuration Two-position

normally open (no version) or normally closed (NC version).

Output configuration Two groups (2 outputs per group)
Maximum switching voltage, AC 250 V
Maximum switching voltage, DC 30 Volts
Maximum switching current per channel
  • for resistive load — 7 A (for version NO), 3A (for NC)
