In Booth C-3813 Tapeswitch Corporation (Farmingdale, NY) will feature its new PSSR-2, a compact safety interface controller for the end of the two wire resistor switch products (switches, edges, mats, bumpers). It offers integrity monitoring of any presence sensing safety switch, mat, edge, and bumper product with a 6.8K 0 or 8.2 K Q end of the line resistor. It uses a manual and auto reset and has three output contacts, force guided relays and two normally open (safety) 1 × normally closed (monitor) contacts. It is 22.5 mm DIN rail mountable.
