2-channelrelay

2-channel relay

• For installation in a safe area (or NIS area)• Transmits to the safe (NIS) area 2 signals received from thehazardous (IS) area•Provides galvanic isolation of the circuits between the IS area and theNIS area• Relay can be supplied with 24-48 V DC, 110 -140 V~, 200-240V~ • Mounting on EN 50 022 rail• Input signal (from hazardous area) selected by jumpers – 2-wire NAMUR proximity switch– volt-free contact (switched current 8.2 V, 8 mA)•Output signal (safe area): electromagnetic relay, 2 changeover switches–6 A max. (at 24 V)– max: 5 A, 250 V, 10 Hz (switching frequency)• Direct or reverse repeater selected by jumper•Connection: 2-conductor cable, dielectric strength 500 V, cross-section 2.5mm
