Details
One 0/4–20 mA input (current input mode: 0/4–20 mA; 18 VDC maximum;
108 Ω and 0.4 V maximum loop burden).
Two (basic model) or three (advanced model) 0/4–20 mA outputs (0/4–20 mA
current loop; external loop power 18 VDC maximum or internal loop power
14 VDC minimum, 18 VDC maximum; loop burden 3.6 V maximum at 25 mA).
Two high voltage relays; Form C, SPDT, 20–230 VAC, 2.0 A
Two digital inputs; each digital input has a positive terminal and a shared
common with an input resistance of 120 kΩ and maximum input voltage of 30 V.
The default threshold is 1.5 V. When the optional user-supplied threshold is
used, the threshold is set at 50% of the voltage applied to the threshold pin (0 to
25 VDC)
Two digital outputs; low voltage contact closures mapped to alarm events
(±30 VDC or 20 VAC-rms at 0.15 A maximum); optional pull-up resistor to
externally-supplied logic level (0 to 30 VDC)
