INPUT SIGNALS
Analog Input Signal
Apply analog input to Pin 4 as shown on page 8.
For 6 Pin Locking Industrial Connector, DB9 and DB15 pin-outs see pages 91 - 94.
For PROFIBUS pin-outs see page 89.
Standard 0-5 Vdc is the standard analog input signal. Apply the 0-5 Vdc input
signal to pin 4, with common ground on pin 8. The 5.12 Vdc output on pin 2 can
be wired through a 50K ohm potentiometer and back to the analog input on pin
4 to create an adjustable 0-5 Vdc input signal source as shown below.

Simple method for providing setpoint to controllers
Optional 0-10 Vdc: If specified at time of order, a 0-10 Vdc input signal can be
applied to pin 4, with common ground on pin 8.
Optional 4-20 mA: If specified at time of order, a 4-20 mA input signal can be
applied to pin 4, with common ground on pin 8.
NOTE: This is a current sinking device. The receiving circuit is essentially a 250
ohm resistor to ground.
NOTE: 4-20mA output requires at least 15 Vdc power input.
CAUTION! Do not connect this device to “loop powered’”
systems, as this will destroy portions of the circuitry and void
the warranty. If you must interface with existing loop powered
systems, always use a signal isolator and a separate power supply.
