DIGITALINPUT DI1
Operation as
Contact input
Connection of a potential-free contact that is suitable for
switching ‘dry’ circuits.
Switched voltage: 5 V
Current: 0.5 mA
Function
Configurable as direct or inverse switch or push button!
Functions: Operation disabling, reset of stored alarms and the
min/max indicator (slave pointer), the integrator,
enabling the tare function,Sample&Hold amplifier
function, Cal-Test , and zero setting.
OUTPUTS
RELAY OUTPUTS OUT1, OUT2
Contact type: 2 normally open with common
contact connection
Max. contact rating: 500 VA, max. 250 V, max. 2A
at 48...62 Hz, ohmic load
Min. contact rating: 6V, 1 mA DC
Swithing cycles (electrical): for I=1A/2A: ?
800,000/500,000 (at~250V
(ohmic load))
Note:
If the relays OUT1, 2 and 3 are used to operate external contac-
tors, these must be fitted with RC snubber circuits to manufactu-
rer specifications to prevent excessive voltage peaks at
switch-off.
OUT3 AS UNIVERSAL OUTPUT
Parallel current/voltage output with common ‘minus’ terminal
(combined use only in galvanically isolated circuits).
Freely scalable
