DEIF PCM42 | PCM43 | PCM44 | IOM 4∙2 | SCM 4∙1

PCM 4∙4 module specifications（The PCM 4∙4 module is typically used as a controller for an extension rack, should one rack be insufficient. The main and extension PCM modules communicate via ARC-Net.）

IOM 4∙2 module specifications（40 channel multi-function I/O module with analogue inputs, temperature inputs, digital inputs, frequency counter inputs, analogue outputs and digital outputs）

SCM 4∙1 module specifications（The SCM 4∙1 module is a class 0.5 AC measurement and protection module which can be fully configured from the main application. All measurements are available for the main application each period. Two relay outputs are controlled, one is a sync check relay, the other a trip relay controlled by the protection functions to secure a fast and reliable disconnection of a generator in case of electrical failures.）
