Alarm module HBA-22

Heater break alarm for single phase relay contact or SSR drive Supported CT: CTL-6-P-N, CTL-18S Main features For relay contact and SSR drive outputs Heater break alarm supporting control system where proportioning cycle time of the temperature controller is short (approximately 2 seconds or more). Supported CT: CTL-6-P-□ , CTL-18S-□ Use of two pairs of CTs enables this device to be used for three phase heater. Main specification Input type: Current transformer (CTL-6-P-□, CTL-18S-□) Detectable load current: 5A, 10A, 20A, 30A, 100A (depending on CT rating) Alarm sensitivity: Alarm is activated ｗhen the current changes by 15% or more of the rated value (full scale) of the CTL. ※Changes below 15% may not activate the alarm. Alarm output: 2 points, Relay contact, 1a contact Supply voltage: 100/110V or 200/220V, (whichever is specified), 50/60Hz Power consumption: 1.8VA or less Ambient temperature: -10 to 50°C
