No. The Batch Controller is a relay control panel designed to work with the ZM303 Series Indicator’s batching applications. The indicator is required separately.
ZM303 Batch Controller
Turn your ZM303 indicator into a complete filling and batching control system. Automate ingredient dosing, fill/discharge sequences, and multi-step batches with reliable relay-based control.

Reliable Control for Repeatable Batching
Manual filling and batching processes introduce variability. These include inconsistent fill weights, operator error, and slow changeovers that cost time and product. The ZM303 Batch Controller pairs with the ZM303 indicator’s native batching applications to automate the process, giving you consistent, repeatable results without a custom PLC build-out.
Whether you’re dosing a single ingredient or sequencing up to three, the ZM303 Batch Controller provides the relay outputs and safety controls needed to run your filling and discharge equipment directly from the indicator.
Feature |
Customer Benefit |
| Four DIN-mounted, 24VDC-operated relays, 240VAC/8AMPS, DPDT (NO/NC) | Control up to four devices directly. Valves, augers, motors, or indicator lights without adding external relay hardware to your panel. |
| Configurable for two-speed single ingredient filling, up to 3-ingredient filling, independent set-points, fill/discharge, manual/auto preacts, negative filling | One controller, multiple batching methods. Configure the same unit for simple single-ingredient fills or more complex multi-ingredient recipes as your process needs change. |
| Auto-tare on startup | Net weight filling from the first batch. No manual taring step before each run, reducing operator setup time and error. |
| Momentary jog control | Correct under-fills on the spot. Operators can manually top off a batch in real time instead of scrapping or reworking an out-of-spec fill. |
| Large mushroom e-stop switch | Fast, accessible emergency shutdown for operator safety on the plant floor. |
| RS232 (x2), USB Host, Ethernet | Connects into your existing systems. Printers, PCs, or plant networks for data capture and reporting alongside the batching process. |
| IP66 / NEMA 4 enclosure rating | Built for the plant floor, not just a lab. The sealed steel enclosure holds up in washdown-adjacent and dusty industrial environments. |
| 7-digit, 9-segment, black-on-green display, 0.8″ digits | Easy-to-read status at a glance, indoors or in variable plant lighting. |
Built to Work With Your ZM303 Indicator
The ZM303 Batch Controller isn’t a standalone scale. It’s the control panel that lets your ZM303 indicator’s batching application actually run your equipment. The indicator handles the weighing logic and setpoints; the Batch Controller’s relays switch your fill valves, augers, or discharge gates on and off in sequence.
Note: The ZM303 Batch Controller is designed for use with the ZM303 Series Indicator’s native batching applications. View ZM303 / ZM300 Series Indicators →

ZM303 Batch Controller Frequently Asked Questions
The ZM303 Batch Controller supports single-ingredient two-speed filling or sequenced batching of up to three ingredients, depending on configuration.
The system automatically zeroes/tares the scale at startup, allowing net weight filling without a manual taring step.
Yes — the momentary jog control lets operators manually top off a batch in real time if a fill falls short.
The Batch Controller enclosure is rated IP66 / NEMA 4.
