Pulse Width Modulating Slice Modules

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.
