22 DI1 SEL-enable
Digital input:
Switch-over to external interface
(else: local operation)

jumpers. Standard activation:
SEL-enable on = Low
SEL-enable off = High

„Default Level“ set to „H(igh)“ by
jumpers. Standard activation:
REM-SB on = Low

1) The input range is adjustable. When using a range other than 0...10V, the accuracy will decrease proportionally. For example, for a range of 0...5V for 0...100%, the accuracy will be only <0.2% etc.
2) AGND and DGND are connected internally. AGND SEL at Pin 14 is inpedendent. It serves as reference for the difference ampliers of all analogue inputs.
DIx, DOx, +Vcc are referenced to DGND. VREF, VMON, CMON, PMON are referenced to AGND. VSEL, CSEL und PSEL are referenced to AGND SEL.
3) Digital input, depending on the preset with the jumpers:
a) Setting High Range (high threshold): U
in
= 0V; I = -1.5mA, U
in
= 12V; I = +0.7mA; U
in
= 24V; I = +4.5mA, Thresholds: U
Low
= < 5V; U
High
= > 9V
b) Setting Low Range (low threshold): U
in
= 0V; I = -1.5mA, U
in
= 12V; I = 2.2mA, U
in
= 24V; I = +6mA, Thresholds: U
Low
= < 1V; U
High
= > 4V
4) Positive currents are owing out of the device, negative currents are owing into it.
5) With certain device series, the standard level may/can be changed by the user in the device setup menu
6) RSEL (internal resistance set value) is only remotely controllable with power supplies of PSI 9000 series (it is generally required to unlock the option „Internal resistance“ in the device)
