2.6.2 Current Output

Introduction
4 to 20 mA current outputs are optionally available for each pen channel in the recorder models having
display and keypad.
Insulation of output wires
The insulation of wires connected to the relay output terminals shall be rated for the highest voltage
involved. Extra Low Voltage (ELV) wiring (input, current output, and low voltage control/alarm circuits)
shall be separated from HAZARDOUS LIVE (>30 Vac, 42.4 Vpeak or 60 Vdc) wiring per Table 2-6.
Procedure
Refer to Figure 2-16 and follow the procedure in Table 2-14 to wire the current outputs.
Refer to Table 2-12 to see the output function of TB5 with the available output algorithms and options.
Step
ATTENTION To avoid damaging the recorder, be sure that you install the power wires into the
correct screw terminals as shown in Figure 2-9 and Figure 2-10.
1 Turn off the power to the recorder.
Open the recorder door. Loosen the captive screw in the chart plate and swing the plate out.
2
Locate terminal block TB5 on the printed circuit assembly (PCA) for pen 1 or pen 2. (See
3
Figure 2-16.)
Run the output wires through the appropriate conduit hole (see Figure 2-7 and Figure 2-8).
4
Refer to Table 2-6 for acceptable wire bundling.
5 Strip 1/4-inch maximum of insulation from the end of each wire and form end to fit under a
screw connection.
6 Insert the wires under the appropriate screws for the applicable relay output as shown in the
figure. Tighten the screws to secure the wires.
