External totalizing pulse counter
Frequency : max. 10 Hz
Pulse length : selectable 50...1000 ms
Output : 24 V, max. 100 mA
optionally active low or active
high,
galvanically isolated,
short-circuit-proof, limited to
apr. 350 mA,
negative amounts are stored
internally and must be
compensated by positive
amounts before new pulse is
output.
This ensures integral
accuracy also with minimal
belt load.

Data format : 8 data bits, 1 stop bit, no
parity
Isolation : galvanically non-isolated
Connectors : Phoenix MSTB, contat
spacing 3.5 mm, max.
1.5 mm
Character map : ISO-Latin-1 (ISO-8859-1)
Load cell connection
Voltage supply : +/- 6 V AC (+/-3 %)
(apr. 66 Hz
short-circuit-proof
Measuring cycle : 100ms
Resolution : 24 Bit
Load : R (load cell) = min. 80 ohms
Cable length : max. 30 % voltage drop,
max. 500 m
Measuring range : -20mV....+50mV
with VLW:
-1.6mV...min. 32mV
