In this way it is possible, e.g. to monitor a master/slave combination of up to 10 cooling units. Control is achieved via standardised interfaces: RS232 (DB9) or RS485, one PLC interface (DB9). The extension board is built into a 1 U plastic housing. A voltage supply of 24 V (DC) is required. This can be provided externally using a Kycon connector. Packs of Model No. 1 pc(s). 3124.200 Supply includes: – Interface board integrated into a plastic box W x H x D (mm): 136 x 44 (1 U) x 129 – Serial SUB-D cable, 1.5 m Technical details: Available on the Internet Rittal Catalogue 34/Climate control 381
