Pulse Width Modulating Slice Modules

Overview

This product is no longer available. Contact MKS Applications Support for more information.

Our pulse width modulating slice for interfacing with solid state relays (SSR's) module is a compact and high density solution for integrating Pulse Width Modulating outputs with the MKS Automation Platform PAC or CM modules, or with the MultiTherm™ 2000. Each PWM module supports 12 digital inputs and 12 PWM outputs. PWM outputs are typically used in temperature control applications, where the Pulse Width Modulating output interfaces to a Solid State Relay (SSR), which is driving a heater.
