(1) Channel isolation (Q64RD-G)
The Q64RD-G is a channel-isolated module.
(2) Four-channel temperature measurement by one module
The Q64RD and Q64RD-G are capable of measuring temperatures of 4
channels per module. Detected temperature values can be converted into
scaling values (ratios (%)).
(3) Conversion enable/disable setting
You can make a conversion enable/disable setting for each channel. Disabling
unused channels for conversion reduces sampling time.
It also prevents unnecessary disconnection detection on unused channels.
(4) Standard-compliant RTD is usable
(a) Platinum RTD compliant with JIS (Japanese Industrial Standards) is usable
(Q64RD)
Two types of JIS-compliant platinum RTDs (Pt100 and JPt100) can be used.
The types can be selected for each channel on GX Developer.
(b) Platinum RTD compliant with JIS or Nickel RTD compliant with DIN is usable
(Q64RD-G)
In addition to the above 2 types of JIS-compliant platinum RTDs, DIN-
compliant nickel RTDs (Ni100) can be used.
The types of RTD can be selected for each channel on GX Developer.
(5) Connection of 3-wire or 4-wire RTD is available for each channel
For each channel, 3-wire or 4-wire RTD can be connected. By making the
terminals short-circuited, 2-wire RTD can be used.
(6) Disconnection detection
The disconnection of a platinum RTD or cable can be detected on each channel.
(7) Optimal processing selection is available
Selectable options of Sampling processing, Time averaging processing and
Count averaging processing, Moving average and Primary delay filter
A desired conversion method can be selected for each channel.
(8) Optimal range selection is available
(a) Ranges of -20 to 120 , -180 to 600
(Q64RD)
When Pt100 or JPt100 is used, a desired range can be selected for each
channel.
(b) Ranges of 0 to 200 , -20 to 120 , -180 to 600 , -200 to 850 , -60 to 180
can be selected (Q64RD-G)
When a platinum RTD, Pt100 or JPt100 is used, a range of 0 to 200 , -20
to 120 , -180 to 600
When a nickel RTD, Ni100 is used, a range of -60 to 180
for each channel.
and -200 to 850
or -200 to 850 can be selected for each channel.
