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)
  • Settable range:

5A : 20 to 100% of rated value of CTL-6-P

10A, 20A, 30A : 50 to 100% of rated value of CTL-6-P

30A, 100A : 50 to 100% of rated value of CTL-18S

  • 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
