SC10C-B6S1 Signal Conditioner

for direct or indirect fired

SC10C_MS_EN_06.2006

Replaced MS2036-07/05

gas applications

The track mounted SC10 can convert a controller's DC output signal of either 4 to 20 milliamps or 0 to 10 volts, to a 0 to 20 volt DC signal. Toggling between 4-20 mA or 0-10 V is achieved with an on-board three position DIP (dual in-line package) switch: 4-20 mA all positions on, 0-10 V - all positions off.

Selectra® electronic gas flame modulation is a superior alternative to methods such as motor driven butterfly valves. When computer or other process controls are specified instead of standard Maxitrol companion electronic controls, the signal conditioner provides compatibility with Maxitrol modulator / modulator-regulator valves.

Signal conditioners and M/MR valves can be configured for direct or indirect fired applications. They may be field installed on existing equipment or specified for new equipment installation. The SC10C-B6S1 can replace the SC10-A6S2 or SC10-V6S2.

DIMENSIONS: 4.75" W x 3.38" H x 2.09" D

Modulator and modulator-regulator valves are available up to 5 psi (350 mbar) inlet pressure, 30,000 CFH (850 m 4". (For additional valve information see Bulletin MT2035, or consult your Maxitrol sales representative)

SC10 output to valve: a milliamp/voltage input corresponds to a voltage output.

READ PRIOR TO INSTALLATION

SIGNAL CONDITIONER FOLLOW THESE

GUIDELINES:

Three Position DIP Switch

4-20 mA

all positions on

0-10 V

all positions off

1. Transformer secondary must not be grounded in any portion of the circuit external to the SC10 signal conditioner. If existing transformer is grounded, a separate isolated transformer must be used.

2. Multiple SC10 signal conditioners controlled by a signal source with common outputs (terminals 5 & 6) require separate transformers for each SC10 signal conditioner (0-10 V input only).

3. Multiple SC10 signal conditioners powered by a single transformer require isolated signal inputs (terminals 5 & 6) to each SC10 signal conditioner.
