Installation
3.6.3 Output card connections
If the instrument is equipped with the output card option, the mA output card supplies up
to 4 analog (0–20 mA/4–20 mA) signals into an impedance of max. 500 Ohm.
Note: The sc1000 mA output card cannot be used to provide power to a 2-wire (loop-powered)
transmitter.
To make an output card connection:
1. Remove power from the instrument. Remove the probe module cover.
2. Connect the output card to the appropriate slot (
). Use a magnetic
screwdriver to secure the four screws to the card.
3. Install the card connector to the appropriate connection on the main circuit board
(
Figure 17
).
4. Feed the cable through the base of the module and properly prepare and insert each
wire into the terminal according to
and
Table 6
. Tug gently after each
insertion to make sure that the connection is secure.
