ASD SERIES INSTALLATION AND OPERATION MANUAL 19
FEATURES
▪ Isolated Switching:
Provides isolation for PLC open collector or contact switching.
▪ Isolated 5 Volt DC Power Supply:
Used for Main Speed Potentiometer operation (25 mA DC max.).
▪ Isolated 24 Volt DC Power Supply:
Used to power a transducer or auxiliary equipment (50 mA DC max.).
▪ Trimpot Adjustments (Multi-Turn):
Signal Scaling (SCALE) and Signal Offset (OFFSET).
▪ Power On LED:
Provides indication that power is applied.
▪ IND LED:
Blinks green to provide indication that the microprocessor is functioning properly.
▪ Jumper J1 (Signal Input Selection):
"VOLT" position for voltage signal input. "CUR" position for current signal input.
▪ Jumper J2 (Signal Type Selection):
"AN" position for analog signal input. "PWM" position is for PWM signal input.
▪ Jumpers J3 (Signal Source Selection):
"NDBM" position for Main Speed Potentiometer Operation (0
– 5 Volts DC). "DBM" position for
Voltage Following Operation (0
– 10 Volts DC).
▪ Jumpers J4:
Installed in the "LED" position for the IND LED.

– DIRECTION SELECTION
Bidirectional Speed Operation: Wire a Forward-Stop-Reverse Switch to Terminals FWD, COM, and REV. See Figure 34 on page 20.
Unidirectional Speed Operation:
For Forward Speed Operation, wire a jumper between Terminals COM and FWD. For Reverse Speed
Operation wire a jumper between Terminals COM and REV. See Figure 35 on page 20.
