MEASUREMENT RANGE—
0-5 LFL-meters.
INTERFERENCE RESISTANCE—
Immune to sun and flare radiation, up to 750 W/m2
≥
3°
to optical axis and common contaminants.
SELF-DIAGNOSTIC TEST—
Fail-Safe operation ensured by performing all critical
tests once per second.
MODULE HOUSING MATERIAL—
CF8M stainless steel (castable 316 equivalent).
CONDUIT ENTRY OPTIONS—
Two entries, 3/4 inch NPT or 25 mm.
HART COMMUNICATION PORT—
Intrinsically safe port on receiver to connect HART
devices.
OPTICS PROTECTION—
Stainless steel brow provides a degree of protection
against windblown dirt and rain. Heated optics mitigate
against ice and dew formation.
WIRING—
Field wiring screw terminals are UL/CSA rated for up to
14 AWG shielded wire, and are DIN/VDE rated for 2.5
mm2 wire. Screw terminal required torque range is
3.5–4.4 lb.-in. (0.4-0.5 N·m). Receiver can be wired
using 3 or 4 wires. Transmitter requires two wires
(power only).
CERTIFICATION—
CSA:
Standard range and long range models:
Class I, Div. 1, Groups B, C & D (T4) with
intrinsically safe output for HART
communication in accordance with control
drawing 007722-001 (see Appendix B).
Class I, Div. 2, Groups A, B, C & D (T4).
Type 4X.

Special Conditions for Safe Use (‘X’):
The performance of the Infrared Hydrocarbon Gas
Detector Model OPECL as a safety device in
accordance with harmonized gas performance
standards, is not covered by the DEMKO ATEX
certificate.
On-board HART port:
• Rosemount Model 275 HART Communicator:
EEx ia IIC T6.
• Rosemount Model 375 HART Communicator:
EEx ia IIC T4.
• Maximum separation distance between receiver and
communicator is 610 meters.
• The temperature code is linked to the ambient
temperature as the following:
Code T5 for use in Tamb from –40°C to +60°C
• The terminal compartment for OPECL without relays
is designed for either an increased safety “e”
termination or a flameproof “d” termination of the
supply cable. If a flameproof connection is chosen,
then a CENELEC certified cable entry device
certified to EN50018 must be used. The OPECL
with relays requires Ex d cable entry devices only.
