Digital input assignment for input control mode

You need to assign one or more digital inputs with non-exclusive associations to define the active tariff.

If a digital input is used for multi-tariff, it cannot be used for an exclusive association (such as Demand Sync or Input Metering), but digital inputs can be shared with a non-exclusive association (such as Alarms). To make a digital input available for setting tariffs, any conflicting associations must be manually removed at the source of the original association.

You cannot configure any digital input tariff if digital input 1 is not available for association. Likewise, digital input 2 must be available to select more than two tariffs.

The status of the digital inputs is used to calculate the binary value of the active tariff, where off = 0 and on = 1. The calculation of the number of tariffs value can differ, depending on the number of digital inputs that can be selected (i.e., inputs that can be associated with multi-tariff).

Number of tariffs required	Digital inputs required
Number of tariffs required	Configuration 1	Configuration 2
1	—	1 (digital input 1)
2	1 (digital input 1)	2 (digital input 1 and 2)
3	—	2 (digital input 1 and 2)

Configuration 1: 8 tariff assignment using 3 digital inputs

Applicable for PM5650 meter model and PM5500 series except PM5570 and PM5570L

NOTE: There is no inactive tariff with this configuration.

Tariff	Digital input 4	Digital input 3	Digital input 2	Digital input 1
T1	N/A	0	0	0
T2	N/A	0	0	1
T3	N/A	0	1	0
T4	N/A	0	1	1
T5	N/A	1	0	0
T6	N/A	1	0	1
T7	N/A	1	1	0
T8	N/A	1	1	1

Configuration 1: 4 tariff assignment using 2 digital inputs

Applicable for PM5570 / PM5660 / PM5661 / PM5760 / PM5761 / PM5570L / PM5660L / PM5760L meter models

NOTE: There is no inactive tariff with this configuration.

Tariff	Digital input 2	Digital input 1
T1	0	0
T2	0	1
T3	1	0
T4	1	1

Configuration 2: 8 tariff assignment using 4 digital inputs

Applicable for PM5650 meter model and PM5500 series except PM5570 and PM5570L

NOTE: Digital input configuration 0000 means there are no active tariffs (all tariffs are disabled).

NOTE: Any configuration above T8 (i.e., 1001 and higher) is invalid and therefore ignored by the meter (the active tariff does not change).

Tariff	Digital input 4	Digital input 3	Digital input 2	Digital input 1
None	0	0	0	0
T1	0	0	0	1
T2	0	0	1	0
T3	0	0	1	1
T4	0	1	0	0
T5	0	1	0	1
T6	0	1	1	0
T7	0	1	1	1
T8	1	0	0	0

Configuration 2: 3 tariff assignment using 2 digital inputs

Applicable for PM5570 / PM5660 / PM5661 / PM5760 / PM5761 / PM5570L / PM5660L / PM5760L meter models

NOTE: Digital input configuration 0000 means there are no active tariffs (all tariffs are disabled).
