ATX RSI Intrinsic Safety Relays 

• Single channel relay: for installation in a safe (NIS) area or Exd box
• Two channel relay: for installation in a safe (NIS) area
• Intrinsic safety terminal: for installation in a hazardous (IS) area

• Single and two channel relays:
• Provides galvanic isolation of the circuits between the IS area and the NIS area
• 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)
• Direct or reverse repeater selected by jumper
• Connection: two-conductor cable; dielectric strength: 500 V; cross section: 2.5 mm2; distance between cables: 8 mm
• Connection: 2.5 mm2 maximum
• Single channel relay:
• Transmits to the safe (NIS) area one signal received from the hazardous (IS) area
• Relay can be supplied with 24-28 Vdc, 110-140 V, 200 - 240 V
• Output signal (safe area) – electromagnetic relay, 1 changeover switch:
• 6 A maximum (at 24 V)
• Maximum: 5 A, 250 V, 10 Hz (switching frequency)
• Two channel relay:
• Transmits to the safe (NIS) area two signals received from the hazardous (IS) area
• Relay can be supplied with 24-28 Vdc, 110-140 V, 200 - 240 V
• Output signal (safe area) – electromagnetic relay, 2 changeover switches:
• 6 A maximum (at 24 V)
• Maximum: 5 A, 250 V, 10 Hz (switching frequency)
• Intrinsic safety terminal:
• Can be clipped on symmetrical and asymmetrical DIN rail
• Maximum clamping capacity 4 mm2
• 6 mm pitch
