Connection Of Input Circuit - Mitsubishi Electric LE-50PAU Instruction Manual

4.3 Connection of input circuit

1. Analog input
(1) External variable resistor
• To input the signal, using the external variable resistor, connect it as shown below in the following
drawing, turn on the DIP switch SW2 and turn off the SW3 ( input : 0 to 8V ).
• Use a variable resistor of 2kΩ ( linear characteristic ).
(2) LE-30CTN, LE-40MTA, LE-40MTB, LD-FX
• Connect the LE-50PAU power amplifire to the LE-30CTN, LE-40MTA, LE-40MTB or LD-FX ten-
sion controller as shown below in the following drawing, turn on the DIP switch SW2 and SW3,
and set the input to 0 to 5V.
2. Digital input
• Use a switch for small signal suitable to small current (12VDC 5mA ).
• When the power amplifire output is not turned ON / OFF remotely, keep across [RC] - [SN] short-cir-
cuited.
• When the stop gain, bias or aux.power amplifire is not used, keep the [ST] terminal short-circuited and
the [SC] terminal opened.
------ For 1 to 5V input and 4 to 20mA input, refer to page 48.
