RSI Series Intrinsic Safety Relays for Safe Areas
For Flameproof Enclosures
ATEX:
Zone 1 and 2 – 21 and 22
II 2 GD
IP66 – IK10
Applications
1-Channel Relay
2-Channel Relay
• Single Channel Relay:
— For installation in a safe area (NIS area) or Exd box.
• 2-Channel Relay:
— For installation in a safe area (NIS area).
Features
Controls
• Single and 2-Channel Relay:
— 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: 2-conductr cable, dielectric stregth 500 V, crosssection 2.5 mm2 (0.004 in2), distance between cables: 8 mm
(0.315").
— Connection: 2.5 mm2 (0.004 in2) 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: 5a, 250 V, 10 Hz (switching frequency)
• 2-Channel Relay:
— Transmits to the safe (NIS) area two signals received from the
hazardous (IS) area.
— Relay can be supplied with 24-48 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)
