INTRINSICALLY

SAFE

The TX6630 Series Power Supply chassis will convert an ac supply voltage into
a stabilised and regulated Intrinsically Safe source for supplying power to
approved sensors and electronic control devices.

Input voltage options:  110V ac, 230V ac

The input supply is protected by two primary fuses.

 There is a choice of Intrinsically Safe output voltage:

12V dc or 7.5V dc.

  The output circuit is resistively limited in accordance with

certification standards for Intrinsically Safe, ia, equipment.

 The TX6630 Series Power Supply Chassis may be fitted

and wired into an existing Exd housing (specific system
certification may also be required) or into a standard
protective housing that is in a SAFE AREA.

 The TX6620 Series version is the

TX6630 Series Power supply chassis
mounted in a Trolex Exd housing
for use in a Group I hazardous area.

  Intrinsically Safe isolation relays

may be supplied with all versions
for switching control currents
emanating from other Exd enclosures
or high voltage systems.
