Placing a jumper across
terminals 17 and 18 (or 19
and 20) will configure that
analog input for current.

1. Important: 4-20mA operation requires a jumper at terminals 17 and 18 (or 19 and 20). Drive damage may
occur if jumper is not installed.
2. These inputs/outputs are dependant on a number of parameters (see “Rel. Param.).
3. Differential Isolation - External source must be maintained at less than 160V with respect to PE. Input
provides high common mode immunity.
4. Contacts in unpowered state. Any relay programmed as Fault or Alarm will energize (pick up) when power
is applied to drive and deengergize (drop out) when a fault or alarm exists. Relays selected for other
functions will energize only when that condition exists and will deenergize when condition is removed.
5. 150mA maximum load. Not present on 115V versions.
