Carrollton, Tex. —Betalarm 4, a field configurable annunciator, offers a serial communications option that expands its applications range. It is said to provide a cost- effective solution anywhere alarms must be transmitted to or from a programmable logic controller, digital or distributed control system, industrial computer, SCADA system, or other intelligent device that uses the Modbus protocol. Betalarm 4's serial interface alarms can be repeated from one or more local panel annunciators to one or more control room annunciators using a single 4-wire communications loop. www.hathawayprocess.com
