Description
Product Introduction
The Esters Elektronik ATM1613 is a high-precision frequency-to-current (F/I) transducer engineered to condition and convert raw pulse signals into reliable analog values for industrial automation loops. Utilizing a period measurement method, this compact signal converter calculates frequency via the inverse time interval of pulse inputs, updating outputs in approximately 3 milliseconds.
Designed for demanding process environments, the ATM1613 handles inputs from magnetic pickups, tachometers, and proximity sensors, translating them smoothly into proportional current or voltage loops. It is an essential hardware layer for continuous monitoring systems where high linearity and rapid response times are mandatory to prevent control loop lag.

Application Scenarios & The “Trench” Experience
Picture this: It is 2:00 AM at a high-speed steel rolling mill. Suddenly, the main drive control loop erraticizes, sending an improper speed feedback reference to the PLC and causing an emergency line trip. Troubleshooting isolates the failure to an analog signal converter tracking the main turbine’s pulse pickup—internal component drift has corrupted the frequency-to-current scaling. Production is dead in the stock-delivery chain, and waiting weeks for a modern analog redesign is not an option. You pull a certified surplus ATM1613 off the shelf, verify the coding switch ranges match the old unit, set the jumpers, and restore precise speed loop feedback before morning shift rotation.

Transparency SOP: Quality Assurance & Testing
We don’t just ship boxes; we test them on actual signal simulation test benches. Every surplus ATM1613 unit goes through a strict verification protocol before leaving our warehouse:
- Inbound Inspection: Physical check for terminal block integrity, housing clips, and OEM label legibility.
- Bench Power-Up Test: Energizing the internal transformer or DC-supply stage (Option N3) to check for thermal stability and ripple rejection.
- Frequency Injection Calibration: Feeding calibrated sine and square wave signals across various ranges (0.02 Hz to upper kHz limits) to verify linearity and D/A conversion accuracy.
- Output Verification: Measuring current and voltage load responses across 0-20 mA and 0-10 V outputs to ensure zero drift.
- Final QC & Anti-Static Packaging: Wrapped in high-density ESD protection and sealed inside a humidity-controlled moisture barrier bag.
The Veteran’s Tech Trap Guide (Crucial Value-Add)
- ⚠️ Check Your Coding Switches: Before mounting and powering up a replacement ATM1613, carefully verify the internal range coding switch settings against your old unit. An incorrect switch profile will instantly scale your analog output out of range and fault your control loop.
- ❗ Watch for Untrue Motion: If you are monitoring low-speed drives with mechanical gear backlash or rough motion, single-period calculation can cause output jitter. Utilize the software pre-divider setting across multiple periods to smooth out the analog signal.
- ⚠️ Verify Power Supply Jumpers: Pay close attention to whether your unit uses standard internal 115/230 VAC wiring or the isolated 18–30 VDC (N3 option). Forcing line voltage into a DC-optioned unit will instantly fry the internal power regulation circuit.
Frequently Asked Questions (FAQ for Conversion)
Q: Is the ATM1613 still in active production by Esters Elektronik?
A: No. Esters Elektronik officially discontinued the ATM1613 / ATM1615 product line. Finding direct factory-new units requires sourcing certified new surplus inventory.
Q: Can I use the ATM1613 to monitor a complete standstill?
A: The ATM1613 is primarily an F/I transducer meant for analog measurement and control loops. If you specifically require built-in standstill monitoring and integrated frequency relay switching thresholds, you should look for the companion ATM1615 model.
Q: Are these units brand new or used?
A: Our inventory consists primarily of New Surplus and Factory Sealed stock secured from industrial plant spares. Each unit undergoes full frequency injection bench testing prior to shipment.
Q: What warranty comes with the transducer?
A: Every ATM1613 ships with our comprehensive 12-month replacement warranty.
