The JENEsys® Security modules expand a SEC-JENE-PC series controller I/O count and capabilities. The I/O modules use DIN rail-mounting, and has two end mounted 6-pin connectors that support direct-chaining (in-line attachment) to other expansion modules. Alternatively, you can mount the expansion modules onto a different DIN rail, and wire the assemblies together via 6-position connector plugs. This allows multiple assemblies of expansion modules, either in the same or remote JENEsys Security Enclosures.
