The Model 3030 is a microprocessor based batch controller and flow rate indicator/totalizer that is capable of single or dual stage batch control. Two process parameters such as batch count and final batch quantity can be displayed simultaneously on the 16-character display. The Model 3030 has five control inputs, which when switched to ground, perform specific functions such as remote batch stop. Four open collector control outputs may be used to interface with remote devices such as relays, counters, and lights.
