Output Wiring - Omega DPF78 SERIES User Manual

The following diagrams detail the connection of the relay and analog output options. Each relay consist of a form A contact
(Normally Open). NPN transistor or Normally Closed contacts are available with solder jumpers (see Jumper Options).
SOLENOID (Single Stage)
Use Relay A (pins 1 & 2) for single stage preset. When the count or rate (selectable) reaches Preset A, Relay A will
energize. When Relay A closes, current passes through the solenoid for activation. When operating AC solenoids,
we recommend the use of an MOV to reduce inductive kickback (use a diode for DC solenoids).
SOLENOID
ANALOG OUTPUT
The analog output can be selected to output 4-20 mA or 0-20 mA and can be selected to track the rate or count.
Pin 13 supplies 12 to 18V to power the current loop. Pin 14 supplies the current sinking driver. When connecting
a strip chart recorder, make connections as follows:
ALARMS
The relays can be used to trigger alarms which warn the operator that a batch is complete or the rate has
exceeded a set speed. The outputs are programmable to be assigned for rate or count. When assigned to the
count, the relays can have a user selectable on time (duration) or can be latched until reset.
