MTL signal conditioners
MTL1249 signal
converter
voltage / current
The MTL1249 is a single channel signal
conditioner which can accept voltage or current
inputs and provide a voltage or current output.
The signal levels are selected by the user using
switches on the module.
Power for this module is supplied via the power
bus embedded in the DIN rail in conjunction with
the power bus accessories.
