CONTACT RATINGS:
If more than one safety shut-off valve is to be actuated by
the R4348 it is recommended to use separate relay contacts
rather than paralleling from one contact.
MAXIMUM RELATIVE HUMIDITY:
90 % RH at 40oC (not to exceed saturation point)
WEIGHT : 1,5 Kg
FLAME SENSORS AND AMPLIFIERS :
will accept any of the plug-in amplifiers and appropriate
sensor listed .
FLAME INDICATION :
Green LED on face of unit when illuminated indicates
presence of flame. Relay contact enables remote indica-
tion of flame presence to be made.
MOUNTING :
Can be wall, DIN rail of panel mounted.
Subbase: 46176612-501
