Honeywell DR4300 manual Current Output Wiring

Installation

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 2-16and follow the procedure in Table 2-14to wire the current outputs.

Refer to Table 2-12to see the output function of TB5 with the available output algorithms and options.

Step

Action

ATTENTION To avoid damaging the recorder, be sure that you install the power wires into the correct screw terminals as shown in Figure 2-9and Figure 2-10.

1Turn off the power to the recorder.

2Open the recorder door. Loosen the captive screw in the chart plate and swing the plate out.

3Locate terminal block TB5 on the printed circuit assembly (PCA) for pen 1 or pen 2. (See Figure 2-16.)

4Run the output wires through the appropriate conduit hole (see Figure 2-7and Figure 2-8). Refer to Table 2-6for acceptable wire bundling.

5Strip 1/4-inch maximum of insulation from the end of each wire and form end to fit under a screw connection.

6Insert the wires under the appropriate screws for the applicable relay output as shown in the figure. Tighten the screws to secure the wires.
