Analog Cards

The analog cards provide flexibility to users for closed-loop control when using standard PLC to control proportional and servo valves.

The IN122-829A is a general-purpose, user-configurable, P-I servo amplifier. It is used in closed-loop applications where a proportional and/or integral amplifier is needed. The numbers of configuration options provided are the result of many years of experience in designing and commissioning closed-loop systems.

The IN123-825 Buffer Amplifier is intended to interface between the output of standard signal sources, such as a PLC or servo amplifier, and a Moog servo and proportional valve.

It can simplify the use of a PLC in closed loops. It enables old mechanical feedback (MFB) valves to be replaced by electrical feedback (EFB) valves, without changing the servo amplifier.
