The new Adam-4150 and 4168 sensor-to-computer interface modules are designed to be compact in size, yet reliable in harsh environments. With a price starting at $190, the Adam-4150 digital I/O module includes seven input channels and eight output channels with over current/short circuit protection. The Adam-4168 relay output, which has a starting price of $210, offers eight form A output channels. Both modules are said to feature high noise immunity (1 kV surge protection on power inputs, 3 kV EFT, and 8 kV ESD protection), a wide operating temperature range, and a power input range of 10 to 48 VDC. A digital filter function, a digital output support pulse function, and Modbus RTU protocol are also included. An LED display allows users to monitor the status of the address settings.
