ELECTRICAL CONNECTIONS
Screened cable is recommended for signal connections and the screen
should be connected to the
instrument earth. It is good practice to separate signal cables from
power cables and to avoid potential
sources of interference such as electric motors, variable speed drives,
microwave ovens and induction
CHANNEL 1 INPUT (Z110S and Z110D)
10 11 12
PASSIVE INPUT: Connect the module in the current
loop as shown.
The module is powered by the 4 to 20mA current
loop.
+
mA
Voltage Drop at 20mA: 3.8V plus Load Volt drop
(0.02*load resistance), minimum 7V
(e.g. with load of 250ohm Volt Drop is :
3.8V + (0.02*250) = 8.80V)
CHANNEL 1 OUTPUT (Z110S and Z110D)
+
mA
ACTIVE OUTPUT: The module generates a current
in the output loop identical to the
current in the input loop. It is capable of driving into a
maximum load of 500ohm.
