摘要：A one time programmable (OTP) electronic switched-output controllerapparatus comprises a plurality of switched-output relays which may be power relays,signal voltage relays, dry switching relays or any combination thereof. A power sectionreceives AC line power and provides at least one internal operating DC voltage andprovides line AC power to any power relays and to the related power outputs when therelay are actuated. An A-D converter provides DC voltage for internal operation and toany DC voltage relays. A one time programmable microcontroller, which has outputsconnected to the relay coils, is programmed before installation in the switched-outputcontroller apparatus to cause actuation of the relay coils in accordance with apreestablished operating protocol. The apparatus is shown connected for receivingRS232 signals and has an internal modem for receiving external signals over a telephoneline. A relay enables switching between the RS232 and modem inputs. Provision is alsomade to receive other external signals, for example, from temperature or pressuresensing devices. A corresponding method of manufacturing the OTP switched-outputcontroller apparatus is disclosed.
