Woodward 41
Analog Outputs
The control has four 4-20mA current output drivers, with two outputs per ATM.
Applications using analog outputs must, within the control’s program, have the
desired analog value assigned or configured to a specific output. Refer to
Volume #3 of this manual for a complete list of programmable analog output
options.
Wiring Notes:
•
Refer to Figures 4-21 and 4-22 for Analog Output wiring connections on the
ATMs.
•
Only 4–20 mA signals are output.
•
All analog outputs can drive into a maximum of 600 Ω .
•
It is recommended that 0.75 mm² (20 AWG) or larger twisted/ shielded wire
be used between each meter (or DCS input) and ATM.
•
Shields should be connected to earth ground at all intermediate terminal
blocks, as well as terminated at the control terminal block. The exposed wire
length, beyond the shield, should be limited to 25 mm (1”).
•
Cable shields must be electrically continuous from the signal source to the
point the signal wire enters the 5009 Field Terminal Module.
•
ATM terminals accept wires from 0.08–2.5 mm² (27–12 AWG) wire.
•
Analog outputs are not isolated; care should be taken when interfacing to
other non-isolated devices to prevent wiring faults. The use of an isolator is
recommended.

Actuator Outputs
The control has two proportional actuator output drivers (one output per ATM).
The actuator output drive currents can be programmed to interface with
Woodward Governor Company actuators (typically 20–160 mA drive currents) or
non-Woodward actuators (4–20 mA drive currents). Each actuator output can be
individually configured to interface with Woodward or non-Woodward type
actuators.
