WESTINGHOUSE 1C31194G02

Description

WESTINGHOUSE 1C31194G02
When using the I/O Builder to configure the Valve
Positioner (VP) module, note that whatever voltage/
current description is displayed in the Slot position at
the top of the window does NOT impact the
configuration of the VP module.
Electronic Modules
There are two 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.
25-2.2. Personality Modules
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 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.

When using the Point Builder to define points for a Valve Positioner module, only the following point types
are valid for each channel:
I/O Name Type Input Source or Terminal Block
Channel Output Destination Connection 2
1 Shutdown Status Input Valve Positioner DI1
2 Auxiliary (wetting) Voltage Sense Input Valve Positioner DI2
3 SLIM ON Signal Input Valve Positioner DI3
4 Position Feedback Input Valve Positioner
5 Coil 1 Voltage (Read-back) Input Valve Positioner Coil 1
6 Coil 2 Voltage (Read-back) Input Valve Positioner Coil 2
7 Coil 3 Voltage (Read-back) Input Valve Positioner Coil 3
8 Raw Demodulator Voltage Input Valve Positioner
