Features:
- Eight independently configured optically isolated pulse channels
- Three documented electrical ranges for contact and pre-amplified signals
- Period, frequency, totalize, and duration operating modes
SPDSM04 combines pulse acquisition and per-channel isolation for Symphony Plus controllers.
Its range selection distinguishes conventional contact levels from lower-amplitude pre-amplified sources.
A useful acceptance test couples a known waveform with the exact processing mode used by the control strategy.
Availability of SPDSM04 is subject to Apter Power's current inventory and sourcing confirmation.

Electrical input selection
- 5 VDC contact: apply the documented low-voltage thresholds.
- 24 VDC contact: match the termination-unit field supply.
- Pre-amplifier: reserve the low-level range for the stated waveform.
- Isolation: retain each channel boundary in cabinet wiring.
Measurement behavior
- Period: configure interval measurement for the intended calculation.
- Frequency: preserve scaling and engineering units.
- Totalize: define reset and rollover treatment.
- Duration: validate pulse-width interpretation with a known source.
High-rate acceptance
- Source: use a traceable pulse generator.
- Duty cycle: apply the documented 50 percent condition at the upper limit.
- Threshold: verify the selected electrical range before the rate test.
- Result: compare controller values with the injected waveform.
