D20AC Option
Description
WESDAC D20AC (40-150V, 511-0104)
Standard version of the AC analog input peripheral logic panel,
supporting up to six 50/60 Hz AC voltage inputs, and up to nine
50/60 Hz AC current inputs. The 511-0104 requires a power source
between 40 and 150 VDC.
WESDAC D20AC (20-60V, 511-0106)
Standard version of the AC analog input peripheral logic panel,
supporting up to six 50/60 Hz AC voltage inputs, and up to nine
50/60 Hz AC current inputs. The 511-0106 requires a power source
between 20 and 60 VDC.
WESTERM D20ACL 3VT/3CT (517-0380)
Termination panel for the D20AC, supporting three AC voltage
inputs and three AC current inputs, which connect through a barrier
terminal strip.
WESTERM D20ACL 3VT/6CT (517-0381)
Termination panel for the D20AC, supporting three AC voltage
inputs and six AC current inputs, which connect through a barrier
terminal strip.
WESTERM D20ACL 3VT/9CT (517-0382)
Termination panel for the D20AC, supporting three AC voltage
inputs and nine AC current inputs, which connect through a barrier
terminal strip.
