For system integrators and engineers, new I/O modules from Opto 22 provide more options for bringing field bus networks into groov Epic, as well as meeting requirements for temperature control applications with high I/O count. GRV-CCANI-2 (serial communication, two channels, CAN 2.0B, channel-to-channel isolation) is the first module in the groov EPIC platform to provide hardware support for an industrial field bus. GRV-ITM-12 (analog input, twelve channels, thermocouple or millivolt) provides a high-density, low-cost temperature sensing option with two isolated zones and six channels per zone.
