The PAM-193-L is a dual-channel valve amplifier for the 0.6–1.2 A range; it is parameterized via analog potentiometers and does not require a computer.
The PAM-193-L is a current-controlled valve amplifier designed to drive proportional directional valves.
The module is designed for installation in a shielded EMC enclosure (control cabinet) and mounts onto a DIN rail. It has an IP20 protection rating.
It uses a 4–20 mA or 0–10 V input signal for control. The maximum output current of the PWM power stage driving the solenoids is 1.2 A. Current regulation is independent of the supply voltage and solenoid resistance.
Key parameters of the PAM-193-L include the input signal type (AIN) and current range (CURRENT) - selectable via DIP switches - the ramp function (RAMP) for setpoint changes, valve optimization parameters (MIN and MAX), and potentiometer-based settings for dither frequency (DITHER) and dither amplitude (DAMPL).
The configuration is hardware-supported via the potentiometers on the front of the module and via the DIL switches on the circuit board.
The PAM-193-L is a straightforward valve amplifier for the analog control of proportional directional valves.
