Switch-to-Loop
Converter Model 460 from Time Mark
Description
Liquid level controllers generally
require a 4-20mA loop current that represents zero to 34.6
feet. The loop current indicates the level of liquid in a
tank or reservoir, and is usually generated by an expensive
pressure transducer or ultrasonic sensor. If you already have
a tank with float switches installed, the Model 460 Switch-to-Loop
Converter allows you to take advantage of the latest liquid
level control, without the added cost of a transducer.
The Model 460 Converter outputs a specific current value as
each of the six inputs are closed. Current values are individually
adjustable between 4 and 20mA for each switch input. Up to
six switches can be used as inputs to all liquid level devices
accepting a 4-20mA input, such as Time
Marks Model 4052.
When an input switch is
closed, the output changes to the corresponding current
level. The highest of the 6 input switches (that is closed)
determines the level of current at the output. If none of
the switches are closed, the output is 4mA. Front panel
LEDs indicate when input switches are closed. A high current
power supply provides a minimum of 50mA to each external
switch.
