Emerson KJ3222X1-BA1 CE4003S2B3 EMERSON module

Description

There are two CE4003S2B3 Electronics module groups for the Valve Positioner module:

• 1C31194G01 provides 17 Volts AC peak-to-peak 1 KHz LVDT drive.
• 1C31194G02 provides 23.75 Volts AC peak-to-peak 3 KHz LVDT drive.

There are four Personality module groups for the Valve Positioner module:

• 1C31197G01 has 330 Ohm resistors that provide up to ±24.9 mA into 82 ohm

servo coils. Use with any Valve Positioner Electronics module.

• 1C31197G02 has 360 Ohm resistors that provide up to 16.8 mA into 250 ohm

servo coils. Use with any Valve Positioner Electronics CE4003S2B3 module.

• 1C31197G03 has 240 Ohm resistors that provide up to 8.3 mA into 1000 ohm

servo coils. Use with any Valve Positioner Electronics module.

• 1C31197G04 has 160 Ohm resistors that provide up to 36 mA into 125 ohm

servo coils. Only two coils may be driven by 1C31197G04. Use with any

Valve Positioner Electronics module. The C3+ and C3- coil outputs are

not available.
