RTU mode = NONE, EVEN, UNEVEN
ASCII mode = EVEN, UNEVEN
• Response time:
Direct data access = typically 25 to 50 ms
Auto-scan buffer (data area) = typically 3 to 5 ms
Signal on alarm Current output:
Failsafe mode selectable (e.g. in accordance with NAMUR recommendation NE 43)
Pulse / frequency output:
Failsafe mode selectable
Relay output:
De-energized by fault or power supply failure
MODBUS RS485:
If an error occurs, the value NaN (not a number) is output for the measured values.
Load see "Output signal"
Switching output Relay output:
Normally closed (NC or break) or normally open (NO or make) contacts available (default: relay 1
= NO, relay 2 = NC),
max. 30 V / 0.5 A AC; 60 V / 0.1 A DC, galvanically isolated.
Low flow cut off Switch points for low flow cut off are selectable.
Galvanic isolation All circuits for inputs, outputs, and power supply are galvanically isolated from each other.
