SG2 series
Relatively complete models: 10/12/20 points AC and DC hosts, with options for analog input/output, temperature input, relay or transistor output. The I/O points can be expanded to 44 points, including 3 sets of 8-point (4-point input/4-point output) expansion modules, 1 set of analog input modules, 1 set of temperature input modules, 2 sets of analog output modules (2-channel voltage or current output), and 1 set of communication modules.
