Analog Output Wiring (4-20 Ma, 1-5 Vdc) - Siemens Moore 353 User Manual

UM353-1
3. Crimp-On Connector - Insert the resistor lead and any signal wiring into the
connector until the wire ends are visible at the pin end of the connector.
Use a standard electrical connector crimp tool to crimp the connection. Be
certain that all resistor leads and signal input wires are inserted in the
connector before crimping.
4. Loosen the two terminal screws using a straight blade screwdriver with a 1/8" (3 mm) blade width. Insert
wires, resistor leads, or a crimp-on connector pin into the two openings in the side of the connector adjacent to
the selected terminal numbers.
5. Check that all involved components and station wiring are fully inserted and carefully tighten the screws to 5
in. lbs. Do not over tighten.
6. Repeat steps 1-5 for each 4-20 mA, 1-5 Vdc and millivolt input.
7. Carefully dress resistors and wiring so that excessive stress is not placed on a component, wire, or connection.

8.4.3 Analog Output Wiring (4-20 mA, 1-5 Vdc)

Analog output functions blocks are AOUT1, AOUT2, and AOUT3. Figure 8-12 shows connections for an external
device that accepts 4-20 mA. For an external device that needs 1-5 Vdc, see Figure 8-13. Refer to Section 8.4.2 for
wiring guidelines.
