Series-PTA

PWM to Analog Current / Voltage Output Interface Device

Converts PWM pulses to analog control: PTA modules convert a single pulse-width modulated input into a linear voltage or current output for control and automation applications.
Ideal for drive and actuator interfaces: Designed for variable speed pump drives, variable frequency fan drives, electric actuators, duty-cycle control, and digital-to-analog conversion.
Flexible input compatibility: Accepts relay contact closure, transistor, or triac pulse inputs with optically isolated signal handling and positive or negative polarity support.
Selectable voltage outputs: DIP-switch selectable ranges include 0-1 VDC, 0-4 VDC, 0-10 VDC, 0-13 VDC, 1-2 VDC, 1-5 VDC, 1-11 VDC, and 1-14 VDC.
Current output support: Provides selectable 0-16 mA or 4-20 mA output, plus adjustable 0-20 mA for custom applications.
Adjustable span and offset: Built-in potentiometers allow users to fine-tune minimum and maximum output levels beyond preset ranges.
Stable no-wrap output: Holds the last output value until the next pulse ends and prevents wraparound when an excessively long pulse is received.
High-resolution signal conversion: 256-step output resolution supports smooth analog control from pulsed digital commands.
Panel-friendly installation: Compact UL94 V-0 snaptrack package with 90° pluggable screw terminals supports clean interface-panel wiring.
Backed by ACI quality: RoHS2 and WEEE compliant, with ACI’s two-year limited warranty.
