Norstat now offers a category 4 Safety Relay designed specifically for Safety Mats and Safety Edges.
The SAFE CM Safety Relay is designed specifically for use with safety mats, safety edges or similar devices. The relays come standard with 4 wear-free semiconductor outputs (OSSD) and logical “AND” link. As a result, the device is suitable for applications where high amounts of frequent actuations take place. Short-Circuit mats with a terminating resistor of 8.2 kΩ (2-wire technology) and 4-wire technology are also supported. Control relay functions can be achieved with the additional “AND” linkage as well as having the option for manual or automatic start.
SAFE CM Safety Relays are 24VDC with a short circuit proof contact fuse, wear-free safety semiconductor outputs and LED indicators for power, channels 1 & 2 plus flashing codes for diagnostics. All SAFE CM Relays are TUV, UL and CUL approved and can operate in temperatures from -25 °C to +55°C.
