Safety relays and control modules differ from conventional relays in that they have force-guided or positive-driven contacts

Programmable automation controller (PAC) modules are add-on devices that perform a specific control function in PAC systems

Programmable automation controller (PAC) systems consist of PAC modules, each of which performs a specific function.

Programmable automation controllers (PAC) are compact industrial controllers used in applications such as data acquisition and control, machine vision control, and process control.

Fire alarm control panels (FACP) are systems which receive information from input devices (smoke detectors, heat detectors, etc.

Machine safeguarding, presence sensing devices control machine operations and protect personnel by detecting the presence of objects that could interfere with or be harmed by machinery

Electrical current sensors measure AC and/or DC current levels.
