Product Description

Johnson Systems PRLC-4 Room Linker/Combiner - 4 x DMX Input - DMX512 Output

Presidor Room Linker/Combiner (PRLC-4) is an intelligent multi-port DMX512 merger designed as the “hub” for the Presidor Wall Stations (PWS). PRLC-4 will allow input streams of DMX512 data to be merged when contact inputs are “patched” to create a larger room/zone. Each PRLC-4 will support up to 4 rooms/zones of PWS wall stations (DMX512) with isolated DMX inputs and an integrated 48VDC power supply to each room/zone. Multiple PRLC-4’s can be cascaded together with RJ45 connection to permit up to 25 rooms/zones of PWS controls merged into a single DMX512 output. Field connections are either via RJ45 with Cat5/5e/6 wiring or terminal block over existing Belden 9773 wiring. Four (4) programmable maintained dry-contact inputs permit PWS (Presidor Wall Station) linking in any possible room/zone combination. At only 1RU in height the PRLC-4 will fit in any standard 19" rack or can be supplied with a small purpose built 19" wall mount rack (PRLCR-4U).
