(4)AO is current type:
Set AO parameter as Power, Upper Limit is ±100%, Lower Limit is 0%, Full Range Value is
12kW. When the Measured Value is -6kW, AO is:
Note:
1. For -100% - +100% setup, the Upper Limit value must be larger than the Lower Limit
value. For all other setup, the absolute value of Upper Limit must be larger than the ab-
solute value of Lower Limit. All Upper Limits cannot be set as 0%.
2. When the Measured Value is out of the Lower Limit, AO will be 0V/1V or 0mA/4mA.
When the Measured Value is out of the Upper Limit, AO will be larger than 5V/20mA, but
the maximum will be 6V/5.8V or 23.2mA/24mA.
Relay Output
AcuDC 240 series IO option has two relay outputs, which are terminal R11(21), R12(22) and
R21 (23), R22 (24). They can be used to remotely control circuit breakers.
The relay outputs are Form A (normally open) electromagnetic relay. The nodal capacity is
3A/250Vac or 3A/30Vdc. If the coil current is high, a medium replay is recommended.
