Technical data RMS621
62 Endress+Hauser
Max. number:
• 8 x 0/4 to 20 mA/pulse (depends on the number of extension cards)
• 6 x digital passive (depends on the number of extension cards)
Signal sources
All available multifunctional inputs (current, PFM or pulse inputs) and results can be freely allocated
to the outputs.
Switching output Function
Limit relay switches in the operating modes: minimum/maximum safety, gradient, alarm, saturated
steam alarm, frequency/pulse, device error
Switch behaviour
Binary, switches when the limit value is reached (potential-free NO contact)
Relay switching capacity
