I/O Wiring – Model 2400S Analog Transmitters

3.4.2 Frequency output wiring

Frequency output wiring depends on whether you will use internal or external power. The following

diagrams are examples of proper wiring for these configurations:

• Internal power – Figure 3-7

• External power – Figure 3-8

Figure 3-7 Frequency output wiring – Internal power

Figure 3-8 Frequency output wiring – External power

Excessive current will damage the transmitter. Do not exceed 30 VDC input. Terminal current must be

less than 500 mA.
