Input Connections
Each channel has two input paths, A and B, that support different nominal input
signal ranges. Sensor wires connect directly to transmitter input terminals at TB1
(channel 1) and TB3 (channel 2) at the bottom of the module (the spring-loaded DIN
clip side, as shown in the connection drawing below). Observe proper polarity
when making input connections and make sure that you connect your signal to the
correct input terminal (input return is the middle terminal).
•
Unit has three operating modes
: You may operate this unit as a dual
transmitter, a single transmitter, or a CH1 signal splitter.
•
Dual Transmitter inputs at TB1 (channel 1) and TB3 (channel 2) are isolated
from each other and from their respective outputs at TB4 (channel 1) and TB6
(channel 2), and from power at TB5
. Each output has separate terminals for
driving current or voltage which share an output return.
•
Inputs are polarized ±, observe proper polarity.
The outside terminals of TB1
and TB3 are positive inputs A & B
and labeled “+”
. The common return for
input paths A & B is the middle terminal of the terminal block. See connection
figure below per input model.
•
DT336 ±20mA DC Current is wired to the leftmost terminal of TB1/TB3 and
±0.5VDC is wired to the rightmost terminal of TB1/TB3. The return for these
signal paths is the middle terminal of TB1/TB3.
•
DT337 ±1V DC maximum is wired to the leftmost terminal of TB1/TB3 and
±10V DC maximum is wired to the rightmost terminal of TB1/TB3
.
The return
for these signal paths is the middle terminal of TB1/TB3.
•
DT338 ±15V DC maximum is wired to leftmost terminal of TB1/TB3 and ±150V
Battery Sources DC maximum is wired to the rightmost terminal of TB1/TB3
.
The return for these signal paths is the middle terminal of TB1/TB3.
