digital output module output types have a general exchange output module and DC output. Generally used in examples input DC output module, the output loop drive through the control of the DC load small relays to control solenoid valves converted signals compressed air valves for control of the scene

Digital output module output type AC and DC output module output in two ways. Generally use the input DC output module in the instance, output circuit controlled by driven DC load device of relays to control solenoid valves and other converted to a compressed air valve control signal on the field, t
