3-2 230V Connection

Input Terminals

A voltage or current signal from a microprocessor, tachometer, transducer, etc. is to be connected to terminals “5” through

“8”. The selection of the proper terminal is based on the maximum level of the input signal. See Figure 3-3, Table 3-1 and

Figure 3-4.

Current Signal Input

WARNING: READ SAFETY WARNINGS BEFORE ATTEMPTING TO USE THIS CONTROL.

The Signal Isolator accepts 4-20mA DC input to provide 0-9VDC output. Connect the current signal input common (-) to

Terminal “5” and the positive (+) to Terminal “6”, as shown in Figure 3-3. Other current signal input ranges can also be used

by installing appropriate resistors across terminals 5 and 6. Calibrate the Signal Isolator in accordance with the procedure

described below.

Note: Two resistors for 10-50mA and 1-5mA inputs are supplied in the hardware bag included with this kit.
