Control and monitor with Sealevel eI/O-160E and 160PoE TTL I/O modules
Control and monitor up to 32 channels of buffered drive TTL digital I/O via any 10/100BaseT Ethernet connection with the eI/O-160E digital I/O module. The eI/O module addresses the 32 channels of I/O as four eight-bit ports, each programmable as input or output. A 50-pin header connects the module to industry-standard solid-state relay racks to […]
New analog input solid state proportional controllers
CARLO GAVAZZI is proud to announce the launch of their new Single Phase RGx1P Proportional Output Controllers. With a typical solid state relay, the output from measuring or monitoring devices is an analog signal that needs to be converted to a discrete signal to control a ‘common’ solid state relay. This can be costly, complicated […]
