In many process control applications it is necessary to be able to control a device manually. Often a
potentiometer or rotary switch is used, but this method cannot be easily repeatable and it may be too
coarse. Micro Systems & Controls have designed a versatile and easy-to-use selection of manual
stations, using their auto manual station AM201. AM201 provides an automatic and manual analog
control output to process controllers, speed controllers and actuated devices. Input to the station can
be a manually set process value (4 to 20 mA) or auto command from higher end system. The input
signal automatically controls the analog output from the auto manual station to the controlled device in
the auto mode. If in any circumstances the input signal gets disrupted AM201 could be transferred to
the manual mode. AM201 returns back to auto mode by ramp up or ramp down at the programmed
rate-of-change when the input signal comes to its proper normal condition to provide bumpless transfer
between modes. Front panel control enables easy modification of system parameters. The digital
display for process value and output command value along with the LEDs for status indication of auto /
manual mode provides convenient monitoring of the signals.
