For ML6984 and ML7984
INSTALLATION INSTRUCTIONS
APPLICATION
The 272630D auxiliary board is an optional
circuit board that is used in conjunction with
Series 4000 ML6984 and ML7984 globe valve
actuators. This auxiliary board combines the
function of an adjustable low voltage SPDT
auxiliary switch with a 2-10 Vdc or 4-20 mA
position feedback signal. It has a 4-pin keyed
connector for communications from the mother
circuit board.
SPECIFICATIONS
Feedback: 2-10 Vdc (10-2 V reverse acting)
into minimum impedance 500 Ω.
Maximum output current is
20 mA dc.
Auxiliary Switch: SPDT, 24 V, 50/60Hz, 1 A
inductive. Fixed differential
(3% of stroke), adjustable
operating point from 0 to
100% of stroke.
