TX6661 Ex D/Ex I ISOLATING RELAY UNIT

Four isolating relays, housed in an Ex eq enclosure for interfacing between Ex i and Ex d control circuits.

The operating coils of the relays are Intrinsically Safe and the contacts are clearance compatible for switching non-intrinsically safe apparatus or other devices in separate Ex d enclosures. The relay coils can be rated for wither 7.5 V dc or 12 V dc operation and each relay carries one changeover contact.

Robust stainless steel housing couples directly to standard Trolex housings.
