The 4800 Controller from Industrial Scientific is an 8-48 analog input controller. With its optional onboard relays, the 4800 can control alarms, fans, horns, etc., when alarm conditions are reached. Being fully programmable, relays can be set to activate from multiple channels, or multiple relays can be programmed to a single channel. Time delays can also be programmed for each relay. This allows the relays to activate after alarm conditions are met for specified periods, or deactivate after a specified time prior to an alarm.

Along with monitoring analog signals, the 4800 Controller can also monitor up to 72 digital ModBus RTU inputs. The 4800 can be set up as a ModBus RTU master unit to monitor these channels, or it can be set up as a ModBus RTU slave device. As a ModBus RTU slave device, the 4800 Controller can communicate to SCADA, HMI, and PLC controlled systems.
