potentiometers
The MTL1173 is a single channel
potentiometer converter with 4-20mA and
1-5V outputs
Power for this module is supplied via the power
bus embedded in the DIN rail.
The PBUS6.2 kit must be ordered separately.
10 x 2 way power clips are provided to power
20 modules.
The MTL1991 or PBUS02 is used to feed
power onto the bus.
