Description
The PAM-193-H is an analogue-controlled power amplifier for single-channel proportional valves with a GND potential connection.
Here is a summary of the key properties and features:
Order number:
- PAM-193-H – Analogue-adjustable power amplifier for single-channel proportional valves with a GND potential connection (current ranges: 1.2 A and 2.6 A).
Control: The amplifier can be controlled via various voltage or current signals. Control is via an analogue signal (from a PLC, a joystick or a potentiometer). An ENABLE signal (typically 24 V) activates the functions, and when the unit is operating correctly, this is indicated via a READY output (PIN 5) and the Ready LED.
Output current: The output current is regulated and is therefore independent of the supply voltage and the magnetic resistance. Thanks to a control sensor system on the magnetic circuit feed, the magnetic current return path no longer needs to be routed through the assembly, but can instead be connected to a GND busbar. The output current is monitored for cable breaks and short circuits.
Parameterisation:
- Adjustable via a potentiometer
- Free configuration of ramps, MIN and MAX, dither and PWM frequency
Adjustment: This unit can be adapted to proportional valves from various manufacturers using potentiometers and DIL switches. All standard proportional valves (up to 2.6 A) can be controlled using this power amplifier.
Signal input range: For a wide variety of voltage (0–10 V or 0–8 V) and current signal ranges (4–20 mA).
Compact design: Snap-on module for mounting on a DIN rail in accordance with EN 50022.
LED indicators: LEDs (Ready, A, B) indicate the operating status and any faults.
Typical system structure: The system consists of a proportional valve (*1), a power amplifier (*2) and an interface to the PLC with analogue and digital signals (*3).
Typical applications: Current-controlled operation of throttle or pressure valves.
