Signal Conditioner Modules

The M200 is a family of specialized signal conditioner modules which is used with the HSM/HSL packages but can also be used with any application that requires conditioning or conversion of signals prior to processing by the M4500 or any PLC or controller.

All M200 modules are packaged in a standard 3" X 3" X 1" DIN rail mountable package complete with removable field wiring connectors. Seven different modules are available:

M230: Frequency-to-Voltage Converter
M231: Frequency-to-Voltage Converter with Offset
M240: Resolver Isolation Module
M245: Quadrature Encoder Signal Converter
M263: Opto-Isolator Module (three-section)
M273: High Speed Solenoid Driver

M240: Resolver Isolation Module
 
  • Used to increase noise immunity of resolvers by providing electrical isolation between the resolver and the programmable limit switch (PLS) it interfaces with
  • Transformers isolate the reference signal (R1,R2) and both stator signals (S1,S3 and S2,S4) of resolver format signals
  • Provides 1500 VRMS isolation between PLS and resolver
  • Dip switch selectable transformation ratio of 1:1 or 1:2 on reference signal and ratio of 1:1 and 2:1 on stator signals allows increased flexibility in matching different resolvers to different PLSs and increases noise immunity
