OUTPUT WIRING
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).
(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).

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.
