The track mounted SC11 converts a controller’s
DC output signal of 4-20 mA or 0-10 V to a 0-20 V
DC signal used to control Selectra valves. Toggling
between 4-20 mA or 0-10 V is achieved with an on-
board 3-position DIP switch: 4-20 mA - all positions on;
0-10 V - all positions off.

To Avoid Internal Damage to the SC11 Signal
Conditioner Follow These Guidelines.
1. Transformer secondary must not be grounded
in any portion of the circuit external to the SC11
signal conditioner. A separate, independent
transformer is recommended.
2. Multiple SC11 signal conditioners controlled by
a signal source with common outputs (termi-
nals 5 & 6) require separate transformers for
each SC11 signal conditioner.
3. Multiple SC11 signal conditioners powered
by a single transformer require independent
signal inputs (terminals 5 & 6) to each SC11
signal conditioner.
