6.5 Technical Specifications
Sensor Inputs
The HMG features:
• 4 sensor input jacks (channel A – H) for up to 8 analog sensors,
or up to 4 SMART sensors
• 1 input jack with 2 digital inputs (channel I - J) and
a voltage input of -10 V to + 10 V (shown at channel H)
Connecting the sensors is done using an standard M12x1 plug connector (5 pin).
Channel A to H:
• Automatic detection for HSI sensors (pressure, temperature, volumetric flow
rate transmitters and SMART sensors)
• Connection of standard sensors with current or voltage signals
• Differential channels for channel A - B; channel C - D; Differential channel for
flow rate measurement orifice (shown at channel B)
Channel I and J:
• Frequency channels (speed (rpm) measurement, counting function)
Frequency range: 1 – 30,000 Hz ( ≤ ± 0.1% FS max.)
Switching threshold / switch-back threshold: 2V/1V
Max. input voltage: 50 V; display delay max 2 sec.
