Vega DSGH - Current Loop Output; Auxiliary Input Frequency Signal; Relay

Wiring
• The AC power source voltage input is 100 - 230 VAC ±10% (90 - 250 VAC) at 50/60
Hz, at 15 VA (or 25 VA with optional heater) maximum power consumption.
• Do not share the AC power with transient-producing loads. Use an individual AC
lighting circuit. Supply a separate earth ground.
• The DC power source voltage input is 20–60 VDC (<100 mV, 1/1,000 Hz ripple) at
15 VA maximum power consumption. DC power cable can be part of a single cable
4-wire hookup, or can be separate from output signal cable.
• Wire must meet power per local code.
• Use wire suitable for +40 °C (104 °F) above surrounding ambient temperature.
• All field wiring must have insulation suitable for 250 volts or higher.
Not all connections are required for operation. The power input terminals are
not polarity-sensitive. The HART signal may not operate with some isolating
barriers or other non-resistive loads.
Current Loop Output
The current loop output signal is 4 … 20 mA into 250 - 800 Ω load. Pin 13 is positive (+)
and Pin 14 is negative (-). HART communication protocol (BEL202 FSK standard) is
available on these connections. The output is isolated to standard ISA 50.1 Type 4
Class U.
When using signal (4 … 20 mA output) cables (customer supplied), they must meet
these specifications:
• Maximum cable length is 3,280 ft. (1,000 m)
• All wires should be per local code
When using DC power, the signal and power can run on a single cable 4-wire hookup (2
wires for power, 2 wires for 4... 20 mA).
Auxiliary Input Frequency Signal
Frequency input signal is 0/100 kHz ≤, true digital.
Relay
Relay contacts are rated at 6 A at 240 VAC, 6 A at 24 VDC, or 1/4 HP at 120 VAC.
Frequency input signal is 0/100 kHz ≤, true digital.
