To connect the GMT220:

1. Connect the nominal 24 V supply terminals (+) and (-) on the

motherboard (right-hand side, see Figure 6 below).

2. Connect the analog output (see Figure 6 below) as follows:

Terminal 0: the common wire (-)

Terminal V: voltage output signal (+)

Terminal mA: current output signal (+)

If the current output is chosen, select the output range by using the

current output jumper 4mA (see Figure 6 below). If the range of

4...20mA is chosen, connect the jumper (default). If the range of 0...20

mA is chosen, disconnect the jumper.

damage the product.
