range)
Frequency: 50 to 400 Hz
Alarm Mode: Dual acting: heater element fail detect and control device fail
detect

Isolation w.r.t Main Input Common: 500 Vrms for 1 min. (50 V working)
Not isolated w.r.t. Remote Setpoint or Heater Current inputs, or Analog
Output common
Note: RS485 and the Analog Output commons are not internally isolated
within the controller. The terminating equipment of these outputs must
not share the same common (i.e.. earth ground).
19. ISOLATION BREAKDOWN RATINGS:
AC line with respect to all Inputs and outputs: 250 V working (2300 V for 1
minute).
Main input with respect to Analog Outputs, Remote Setpoint Input, Heater
Current Input: 50 V working (2300 V for 1 minute).
All other inputs and outputs with respect to relay contacts: 2000 VAC
Not isolated between Analog Outputs, Remote Setpoint and Heater
Current commons.
