SPECIFICATIONS
6.1 Electrical Parameters
The mains power connections are made to the transmitter only. There
is a DC-powered transmitter (TB8-xx-06-xx-xx) that requires 18-
36VDC at 25W max. There is an AC-powered transmitter (TB8-xx-05-
xx-xx) that requires 100-240VAC, 50-60Hz at 25W max.
These signals can also be found in Table 2, below. Electrical
parameters of other signals can be found in tables 3, 4, and 5.
6.2 Maximum Surface Temperatures
All three components of the sonar process monitoring system covered
by this manual have temperature classification “T4”. This means that
when properly installed and operating normally they will not produce
hot spot temperatures in excess of 135 ºC.
The following signals are not energy-limited for any of the transmitter models.
Some models may have one-piece screw terminal blocks and others may have
two-piece pluggable terminal blocks with either screw or spring clip terminals.
These terminals will accept 0.20 to 3.31 mm
2
(24-12 AWG) conductor size.
Conductor size 0.82 mm 2 (18 AWG) or larger cross section is recommended.
